Fix Restart and Shutdown Problems in Windows 8 and Later by Disabling “Hybrid Shutdown” Feature

UPDATE: This tutorial will also work in Windows 8.1 and later.

There are many Windows 8 users who are complaining about various restart and shutdown issues. Many times their Windows 8 computers restart themselves as soon as the login screen appears. Sometimes their computer systems hang while rebooting or shutting down the system and sometimes their computers restart or hibernate when they try to shut down.

Most of the times these kind of issues are related with the new "Hybrid Shutdown" (also known as "Fast Startup") feature introduced in Windows 8. Hybrid shutdown feature of Windows 8 decreases the total startup time by hibernating the kernel session instead of closing it which reduces the overall Windows loading time because resuming from hibernated system session is very less work compared to a full system initialization.

But this new feature is causing problems to some computer systems and if you are also facing reboot or shutdown problems in Windows 8, you can fix it by disabling this new hybrid shutdown feature and doing a complete shutdown.

Just follow these simple steps:


First of all you'll need to open Power Options window which can be opened using any of following methods:

a. Press WIN+R keys together to launch RUN dialog box and then type powercfg.cpl and press Enter.

b. Press WIN+X keys together to launch "WIN+X Menu" and then select "Power Options" from the list.

c. If you are on new Start Screen, type power and Windows will automatically search for the term and will show you the results. If you are on Desktop, move your cursor to top-right corner of screen to access new Charms Bar. Now click on Search option and type power in search box. Now click on Settings link given in right-sidebar of search results page and then click on "Change what the power buttons do" link given in the search results as shown in following screenshot:



In Power Options window, click on the "Choose what the power buttons do" link given in left sidebar.


Now scroll down to bottom and you'll see "Turn on fast startup (recommended)" option given in Shutdown settings section as shown in following screenshot:



Disable the option by unchecking the checkbox and then click on "Save Changes" button.

PS: If the option is not shown or grayed out, scroll up and click on "Change settings that are currently unavailable" link. It'll allow you to change the option settings.


That's it. Restart your system and your reboot or shutdown problems should get fixed in Windows 8 and later.

NOTE 1: If the above solution doesn't fix your problem, you can try to execute following command in Command Prompt. Open Command Prompt as Administrator by right-click on the bottom-left corner and select the same option from the Win+X menu:

bcdedit /set disabledynamictick yes

The above mentioned command used to fix a very annoying freezing issue found in Windows 8 Release Preview build. According to Microsoft the issue was fixed in Windows 8 RTM but if you are still facing the issue, you can try the command.

NOTE 2: In some computers, you may also check BIOS settings. If it contains "Fast Boot" or similar option, disable it.

    Thanks for the Solution VG~
    Great Job.

  • Thank you so much for these instructions! I've been battling this problem for 3 days including spending 3 hours on the phone with Dell's technical support team who were not able to solve the problem! I was getting a little impatient since it's a brand new PC so quite cheesed off that it wasn't functioning properly.

  • Dear Concern,
    when I shut down my system, screen gets black but laptop lights remains on means system is still running, I have to shut down by pressing button of laptop.
    kindly suggest me a way?

  • VG

    ^^ Did you try to disable Hybrid shutdown "Turn on fast startup " option as mentioned above? Also have you installed latest drivers for your graphics card?

  • Unfortunately this has not worked for me and my pc which has windows 8.1 keeps on getting rebooted.

  • thanks very much, your method is by far better than Microsoft Care-Center. Saved me time and money. Kudos

  • Thanks a lot friend! You've saved my laptop :P

  • Still not shutting down...did both options...screen turns off but that is all

  • Thank you very much for the solution.
    It's work for me on Windows 8.1 by disabling Turn on fast startup

  • i am still facing problem i am using win 8.1

  • The above instructions are missing a crucial step. In the System Settings window you first have to click on the blue "Change settings that are currently available" link near the top of the window in order to be able to uncheck the "Turn on fast startup (recommended)" option. Hope this helps.

  • VG

    ^^ Its mentioned in PS given between point 4 and 5. :)

  • I disabled the fast boot and then it froze and I started it up and it randomly restarted again after 5 minutes of use, but I booted it again and used the command in CMD and it's been running for 20 or 30 minutes without crashing so far but I'll come back either tomorrow or whenever it might randomly restart or freeze. Thanks so far

  • This is great for those that are able to access the settings; but I am having an issue with the message 'pc ran into a problem, restarting'. It does Preparing auto repair and diagnostics. Than nothing.

  • Thank you for this.
    Its been driving me crazy for the last couple of weeks.

  • Thank you! You solved my problem! Drove me mad!!!

  • I have lenovo G50 laptop.with windows 8.1 suturing restart prob. Notification shows problem in OS to fix this some info is necessary to send it to Microsoft. And it is automatically get restart
    . Please help

  • I tried it; did not work! That procedure actually caused my Acer V3 laptop computer to get back to a state that caused it to completely boot on the second start up! Then I went back to the original configuration; "Turn of fast start-up (recommended)". However, as that original configuration went back and worked, it did not solve the problem of Restart; which still does not work! Just less than a half hour ago there was a Windows Update, and my Acer V3 laptop could not restart! What the hell is wrong with most of those people at Microsoft? Although I am not absolutely sure, this Restart problem began with a Windows Update! How ridiculous and frustrating! I've studied Windows and used this operating system on my own, and for over 11 years I've mostly trouble! I think that eventually I shall go back to a Macintosh computer, latest Mac operating system. I've gone wacky with Windows, so I'm going back to Mac! I made that phrase up.

  • I meant to say "Turn on fast start-up (recommended)". Not "of".

  • Sorry, there I go with another solecism; I meant that for over 11 years I had mostly trouble. I occasionally make grammatical mistakes because I want to get my point across as soon as possible. Anyway, it is ridiculous, and frustration. However, it is also aggravating and ironic, because this Restart problem happened close to a month ago by actually downloading a Windows Update! How ridiculous and ironic is that situation. My Acer V3 laptop was bought in 2013, and now I have Windows 8.1, the latest and greatest version that cannot take on a task to Restart a laptop computer! One day Microsoft Windows 8.1 which eventually change and progress to an operating system of 128 bits! What the hell is with the functioning Microsoft Windows? I've had less trouble, far less Restarting on my Sony VAIO desktop computer (2003), operating on Windows XP; and that smoother operation was before I installed Service Pack 3! How ridiculous. If anybody from Microsoft is listening, get back to where you once belonged, because Macintosh is going strong.

  • Press Win (Key) and type

    shutdown -s -t 0 -f

    Press Enter to shutdown.

  • didn't help on my old pc with P35 chipset, turns off video, hangs forever

  • I tried this procedure, and it did not work. In fact, it went back to having to press the Power Button longer, then starting it again. Therefore, I set it as it was, in its default setting. However, I still have this Restart command problem whereby my Acer V3 laptop computer, bought with Microsoft Windows 8 in late 2013, now upgraded to Windows 8.1, hangs at the Acer logo screen! I then need to hold down the Power Button down for 6 seconds for a forced Shut Down, wait for at least half a minute for the internal hard disk to stop and cool down, then press the Power Button, and my Acer V3 laptop starts up normally, but I think it is ridiculous! I also have a Sony VAIO desktop computer (2003) with Window XP, Service Pack 3, that I am going to upgrade tomorrow with Windows 7. With my Sony desktop I cannot remember experiencing these Restart problems with the older Windows XP OS; except for a faulty memory module, but that case is a different story. Certainly Microsoft can do better with this newer, premium operating system.

  • Hold on, I didn't include a full explanation in my first sentence. I meant to say that with this configuration, it goes back to having to start my Acer V3 laptop computer operating with Windows 8.1 if it is Shut Down, twice before it fully starts up again. Therefore, I set it back to the original configuration, "Turn on fast start-up (recommended)". However, as I mentioned above, the Restart command is a mystery! It cannot fully start, except if a forced Shut Down, by holding down the Power Button, is initiated. As I said before Microsoft can do better with Windows 8.1!

  • Sorry, I forgot, to use my actual name, I am omegaman, that's me, George. I have written and posted problems with the Windows 8.1 operating system above. Please read my posts above. I'm sorry for the confusion. You see, I posted these Restart problems elsewhere, and I got mixed up. Anyway, I still have this Restart problem.

  • Okay, deo, I'll try this procedure, thank you.

  • Hi, tried many workarounds with no luck; updated every driver and latest windows upgrades still windows 8.1 cannot restart.
    too bad windows 7 was able to restart properly :(

  • Listen guys!!!!! If this doesnt help then
    1)Type power in new windows screen and go to settings
    2)If you are using windows 8.1 then go to PC and devices and there you can change the sleep time and black screen time to "Never".
    3)You are done now your computer will not restart or shutdown untill and unless you want to.
    Maybe this can help or the above solution .Try both

  • i have problem to restart my lapi . when i click on restart . system will hangs /black screen appears .the procedure will stops there....reply

  • Thanks a lot got fixed with this

  • I have a Toshiba Satellite laptop, I only bought it in September and it was shutting down fine originally. I didn't change any settings, and the only software I have installed have been mcafee internet security and Microsoft office 365 yet now when I press "shut down" my laptop completely shuts down (the off switch button light goes off and everything", then within about 3 seconds, the light comes back on and the laptop restarts itself. The only way I can turn it off is by pressing and holding the off switch on the laptop but isn't it bad to repeatedly turn your laptop off that way? I have looked at all the forums and checked all the power settings etc but nothing seems to be working! I have also tried turning off with the power unplugged and with all USB devices removed which some forums suggested but no luck. Any ideas?

    In my boot settings, what should my laptop be set to boot up through? It's currently set to HDD but other options include USB, LAN etc, I'm not very experienced with computers so wasn't sure if this had anything to do with it or not. Also built-in LAN is enabled, is that related in any way? All other settings like boot up when lid is open etc are disabled, and I have checked the power options and everything seems to be set how it should be

  • I have a Windows 8 lenovo. Two days ago I was having internet connection problems so I decided to restart my laptop. However my laptop has now been "restarting" for about 30 hours.I've tried to turn it off but when I press the power button to turn it on it is still restarting.

  • VG

    ^^ Press and hold the power button for a few seconds and it'll turn off the computer. Then again press the power button to start it normally.

  • Thank you!! This worked for me.

  • Hey, I have the same issue with my pc from the start, I did everything said here and it worked which really pleased me cause the firm i bought my pc from Always repleid sozz we can't help you...

    To my surprize, the next day the reboot function was gone again, i reinstalled W8 , disabled the hibernation and it was ok again. At the end of the day tough reboot failed again.

    Any thoughts what could bug it else?

  • Thank you so much, it really worked. Keep helping

  • I have a Win 8.1 pro laptop which starts and shuts down well in time but takes a lot time when i log in into my account after restarting.
    Windows restarts well in time but it takes 2-3 mins to sign in into it .
    Please fix this ...

  • VG

    ^^ It might be happening due to several startup programs. Open Task Manager, go to Startup tab and disable unnecessary items from startup.

  • I have an Acer Aspire AX-603G Desktop with Windows 8.1 with 8.1 Update 1 installed. I don't know if it is fixed or not, but it seemed to be last night. This morning it seemed as if it booted in restart mode. I tried the command in the command prompt (admin) this morning, so lets see how that goes. If the command in the command prompt (admin) doesn't work, shall I come back here?

  • Works great in window 8.1 after so many advices from others..

  • OMGGGGGGGGGGGGGG THANKS You so much you saved my life. thanks you. you are the best! i love you more than i love my girl friend.

  • OMG thank you so much. I've tried searching all over, but couldn't find the right answer. You're a lifesaver!!!

  • Thanks a lot guys it really works for me. After I tried the steps it worked. The problem is that my laptop takes longer to restart

  • my experiences:
    windows 8 (upgraded from windows 7, old ocz vertex2) does not restart, hangs the pc (video off, after some time not even numlock works)

    upgrading windows 8 to windows 10 preview has no effect, same issue (also with build 9879)

    another pc with windows 7 on crucial ssd has similar issue with UEFI bios: restart doesn't work even if configuring every setting as legacy and disabling hybrid/fast/quick boot

    this is definitely a bug in windows upgrade and a bug in UEFI bios
    the only solution, so far, is reinstalling from scratch.

  • Good Day!
    Thanks for the help! It sure did solved the problem :)

  • Thanks it worked! My comp could successfully shut down. Seriously though, what were those people in Microsoft thinking when they made the update..

  • I own a lenovo z510 laptop. i installed windows 8.1.

  • Hi, i faced the same restart and shut down issues mentioneed on this post. I had to factory reset my laptop twice! The main issue I noticed was with installing windows updates. I havent installed any updates and the laptop is super responsive and fast. No glitches at all. I have the latest avast intrnet security and advanced system care 8.1 pro installed and everything is fine and dandy for the past 2 days. I have restarted the laptop numeorus time over this span and it works just fine. Windows 8 is absolute shyte! I sincerely hope 10 irons out all these issues. Until then im living without updates. This is just my experience. If it works for some of you facing similar issues try this method out.

    ^^ It seems some services are running in background and causing delay in shutdown. Make sure no unnecessary items are enabled in startup:

  • Thanks a lot for this fix :) It works fine on me for my HP Pavillion!

  • My Dell Inspiron laptop (win 8) froze while updating Avast software. Had to shut down. Now it won't turn on. These instructions don't help me if the computer won't turn on. The power lights are on however. I'm now forced to seek answers from my Win XP laptop. The odd thing is that I went to a site I visit daily and video would load but not the chat. Strange, never had XP problems. I'm quickly becoming very irritated.

  • help didn't work to fix it my problem

  • When i shut down normally the screen goes black but the lights are still on
    i tried disabling the turn on fast satartup but it still doesnt shut down
    please help

  • Hello,

    Does not work for me. Got new spec computer and reboots started recently, 3 days ago where my PC going on reboot itself, i did checked when windows has updates and checked for the latest updated on graphic card - no issue in there. mostly it happened when playing CS:GO.

  • Hi,
    My Lenovo Win 8.1 would sometime decide to restart itself when I left it hibernating, and would sometimes then fail to restart properly, just froze. Power button would usually fix it after two or three attempts. This happened about once a day, So irritating!
    Then noticed it wasn't shutting down properly either. Lights would stay on until I hit power button.
    Tried your fix, all seems OK now, Yeeeh hah!
    Let's hope Win 10 is better!!!

  • I appreciate the effort of writung this article.
    I have build the new x99 based PC that was stuck on win boot every time after the shutdown throuth the windows.

  • Fix Windows 8 and Later Restart and Shutdown Problems by Disabling “Hybrid Shutdown” Feature.
    i used it for intel core i5 pro book 6570B, running window 8 i used the command
    bcdedit /set disabledynamictick yes it work for

  • Thank you so much. Laptop would freeze after shutting down and then booting up again. It would also freeze on restart and then booting up again. I ran (cmd.exe) as an administrator, then it would allow me to access the boot log, then I typed in your command bcdedit.exe /set disabledynamictick yes and it works now. It doesnt freeze on restart or shutdown. Thank you!!!!!!!!!!!!!!!!!!!!!!!

  • Thank you so much..... that was the solution....

  • Thank you! Solved shutdown problem for my Dell Inspiron 2350 that I upgraded with a WD Black2 Dual Drive.

  • Been happening for a while, but the last time I lost info on a document I was working on. It's got to the point I'm reticent to make updates for fear I might be a subject to experimentation and the problems they can create. Anyway, thank you for the info and hopefully problem solved.

  • Thank you very much! Every other fix suggestion just outright failed or wasn't correct in the least. MS support were clueless. But this fixed things, and I can *finally* use my new Lenovo laptop reliably.

  • GREAT!!!
    Awesome and love it!
    Thank you!

  • Fixing on Hybrid shutdown didn't work for me. Whenever my asus laptop sleep or hybernate if I press the power button to wake the pc instead of waking it turn off. Then I need to press the power button only to find that it is now restarting.

  • I can't get to the Search button or Start screen. Whatever the task host is doing is preventing me from getting to the Search or Shut Down options. So I have to leave my PC on and nothing happens when I click on the Windows pane.

  • Have the same problem, pc hangs on shutdown. I tried your suggestions but didn't change anything. What to do now?

  • Works like a charm. I am looking for solution about a month until this article.
    Thanks very much avg.


  • Unfortunately in my case this did not work. I still have the same problem, pc hangs on shutdown, fans continue to run, power button lit. Any other suggestion?

  • Hey, Thanks a lot. The first method worked for me. I am using Win10 on a HP Pavilion Core i7 laptop.

  • I have shut down and restart problem after I upgraded from win 8.1 to win 10.Please help

  • it works, thanks you so so so much. This has troubled me for a long time and it's now fixed.

  • Thanks a lot!!! I fight nearly half year with this problem on my HP laptop. Now works like should.

  • I'm running a Dell Inspiron 64-bit laptop. The system crashed during a Restart for an update from Windows 8.1 and from Windows 10 (twice). All three times my computer was trashed and I had to pop in a Recovery Disk to restore my system (Windows 8), then upgrade to 8.1 or 10. Not fun at all. Dell Technical Support is clueless and wants only to waste my time running hardware diagnostics (they always check good). The problem is obviously with the Windows Restart routine for an upgrade from 8.1 or 10.
    I see the recommendation here, but would like to know if anyone else has had my problem before I gamble on a 4th Restart, I'd rather go to my grave with 8.1 than waste another weekend restoring my system, drivers and applications.

  • VG

    ^^ If you can afford a clean install, I'll advise you to clean install Windows 10. Or you can dual boot:

  • VG,
    How does this get me around the system crash when Windows 10 decides to do an upgrade and Restart? I've already gotten trashed twice by a Windows 10 update/Restart.
    I had made a Windows 10 recovery media, and tried using it after my last crash but it stopped cold halfway through the recovery process. That's when I reverted to Windows 8.1 via an 8.0 recovery disk.
    This is all a bit frustrating given the time required to recover files and applications. At one point I had to copy a 63-digit number to validate my Windows license. Here's a fun fact: if you actually had 10 to the 63rd copies of a Windows' disk, the mass of these disks would exceed that of the largest theoretical black hole by more than a trillion times.

  • VG

    ^^ Thats why I suggested clean install. Upgrading may cause such kind of issues but clean install should work fine.

  • VG,
    I tried to install Windows 10 but each time it got hung up at 75% complete (configuration settings at 1%). This was unexpected and incredibly frustrating because I had previously upgraded to Windows 10 on two other occasions (August and September).
    I did a set of required updates to 8.1 then automatically received notice I was entitled to upgrade to 10. After 3 hours of downloads, installation and configuring, it stopped at 75%. I went to bed for a few hours and it was still stuck on 75% when I awoke. When I restored 8.1 I was told I needed to install yet another required update (Grrr). That being done, I began the Windows 10 upgrade again only for it to stop again at exactly 75%. I then changed PC settings to allow automatic updates, tried again and watched it again stop exactly at 75%.
    At this point I have a clean install of 8.1 and a Recovery Media. I'm fed up with wasting time on Microsoft's latest monstrosity (aka 10), one which I can no longer upgrade to for reasons unknown. Believe me, my system hasn't changed since September.
    Thanks for the suggestions, but I'm cutting my losses and planning to migrate to Apple come the new year. I need to work with a reliable system. I think separating the operating system from the OEM just doesn't work at some point of complexity (I have an Nvidia card, which may be part of the problem).


  • VG

    ^^ You can try a clean install of Windows 10:

  • VG,
    I tried a clean install of 10. Specifically, I tried it through the first link you sent. I used Internet Explorer selecting "Windows Phone" from the "Browser Profile" of the Emulation Tab in the Developer's Window. The installation became stuck again at the exact same spot, 75% complete with the error message, C1900101-4000D.
    The other link you gave me just led to an infinite Do Loop. First you need to upgrade to Windows 10 before you can use the bootable USB drive to perform a clean installation. But if the problem is being unable to upgrade to Windows 10 at all, well, a clean installation is moot.
    All in all, a wasted rainy Sunday afternoon. If you're keeping score, I'm 0 for 4.

    ^^ You can also try to download the ISO file using alternate link given in following article:

    It might be possible that the previously downloaded ISO file was corrupt, hence it stuck at 75%.

  • Hi
    I have a problem. I did you instructions but my problem did not fix. my computer is shunting down and restart later again. do you have any advice for me

  • I know this is an older fix but I recently upgraded a 7 PC to 10 & it would NOT turn off & this fixed it for me. Many Thanks, Jay

  • VG,
    Merry Christmas. I followed the link and downloaded the files onto a USB and tried the upgrade from the USB. It stopped at exactly the same location, 75% complete (I'm 0-5 now). It did articulate the error message a bit more, It stopped while trying to save data, which doesn't help me very much.

    ^^Then it might be a problem in BIOS settings. Try to reset BIOS settings to default and then start the installation. Also you can try to disable UEFI and Secure boot options in BIOS settings.

  • Hi, quick question. Does this mean that the fast startup boasted by many win 10 users is in-fact just a form of hibernation that has existed on windows machines for some time?

    If so, what is the difference between 'fast startup' and simply using the actual 'hibernate' power option?

    Thanks for reading. Fantastic blog, I use it often.

    ^^ Following topic will provide you more details:

  • These steps didn't work in my case either (brand new Asus laptop). I decided to check BIOS, and then give up, return it, purchase a used one with Windows 7.

    However, when entering BIOS>boot, I noticed that the "fast boot" option was still enabled there, as well as a few other things that involved booting. I disabled/enabled accordingly, and it worked.

    The answer to the "never completely shutting down" problem could rest in the BIOS, if the above advice didn't work for you. I had tried all of it, to no avail. Disabling in the BIOS was the only successful step.

  • IMPORTANT NOTE: Hybernate has to be ON.

    I turned it off for saving space on my ssd's c drive and had to activate it for this all to work. When I turned it off again "powercfg -h off", I had the same issues as before.

    So my setting is:
    1. Fastboot in BIOS enabled
    2. Hybernate on
    3. Fastboot in Windows off
    4. I also executed the command "bcdedit /set disabledynamictick yes", but I am not sure if this helped to solve the issue.

  • Was having nightmare issues with shutdown and restart from Task bar. Now finally fixed, thank you for the information. Wish Microsoft would fix their products before they send them out for testing by millions of consumers. There were 168 updates to Windows 7, and 32 for Windows 8.1 Pro. That are all the bugs they left in the system. They cant be bothered troubleshooting it in their own back yard.

  • sir, when i am starting my pc then its show something error and automatically restart ...what i can i do sir.. help me plz

  • VG

    ^^ It seems a Windows problem. Tell more about the error message.

  • vg, thank you for this shutdown/restart fix. Really was a puzzle for me.

  • If you find it's not working, try disabling 'Fast startup" restart your computer and then go back and turn it back on and restart your computer again. This should help.

    If the "Fast Shut down doesn't work try this.

    Under Explorer key, create a new key and set its name as Serialize

    Now select Serialize key and in right-side pane, create a new DWORD StartupDelayInMSec
    and set its value to 0 to disable startup delay time.

    Forgot where I found this, but it may help.

  • Finally an answer to my problem after four years of agonizing restart hangups. Thank you so much.
