[Tip] How to Find Out the Date and Time When Windows was Installed in Your Computer?

Here is an interesting tip for our readers! Recently an AskVG reader "Arif034" asked us following question via email:

Hi, this question might sound crazy but how can I find out the exact install time and date of Windows? I've come across some answers to this query but all of them require juggling with registry or CMD and as a below average user, I'm not at all comfortable with that. Can you please provide me an easy solution? Thank you.

Actually its not a crazy question at all. There might be situations when you may need to determine the installation date and time of Windows OS in your computer system. Sometimes you may want to know out of curiosity when did you last install Windows?

There are many ways to check Windows installation date and time as mentioned below:

  • METHOD 1: Using Windows Explorer
  • METHOD 2: Using SystemInfo Command in Command Prompt
  • METHOD 3: Using WMIC Command in Command Prompt
  • METHOD 4: Using Registry Editor

If you also want to find out install date and time of Windows in your system, here are the details of these methods:

METHOD 1: Using Windows Explorer

This method is the easiest method to have an approximate idea of date and time of Windows installation.

1. Open Windows Explorer and go to the drive containing the installed operating system. Generally its C: drive in most of the systems.

2. Now either change the folder view type to details or right-click on a folder such as Program Files or Windows and select Properties.

3. It'll open folder properties window. Here you can see the folder created date and time. Its almost the same date and time when Windows was installed in your computer.

But there is a slight problem in this method. Since Windows Vista release, Microsoft changed the installation type of Windows to image based which means the setup installer just extracts the required files to your hard drive. So many times the date and time of folder creation will not be the installation date and time of Windows but it'll be the date and time when Microsoft created the Windows image for the setup.

But there is a workaround for this problem! You can check out the folder creation date of your user account folder which is present in "Documents and Settings" or "Users" folder.

Since this folder is created by Windows setup at the time of installation, its creation date and time will be almost the same as of Windows installation.

METHOD 2: Using SystemInfo Command in Command Prompt

The above mentioned method might not provide the exact and correct date and time of Windows installation but you can use following Command Prompt method to get the original date and time when Windows was installed:

1. Open Command Prompt as Administrator using any method given here.

2. Now run following command:

systeminfo

It'll take a few seconds in running some tests and you'll get a detailed information in the result.

3. Scroll upwards a little and look for "Original Install Date" section. It'll show the correct date and time of Windows installation in your system.

You can also take help of '|' parameter to direct find and show the Windows installation date and time via systeminfo command.

Just run following command in Command Prompt:

systeminfo | find /i "date"

It'll only show the Windows installation date and time information.

METHOD 3: Using WMIC Command in Command Prompt

There is another command "WMIC" (Windows Management Instrumentation Command-line) which can be used to find out Windows installation date and time.

1. Open Command Prompt as Administrator using any method given here.

2. Now run following command:

WMIC OS GET installdate

It'll immediately show the install date and time of Windows in following format:

Year Month Date Hour Minutes Seconds

For example following is the result of the above mentioned command in our test:

20131019011658

Here:

2013(year) 10(month) 19(date) 01(hour) 16(minutes) 58(seconds)

METHOD 4: Using Registry Editor

You can also take help of Windows Registry to find out the date and time of Windows installation but it'll be little bit complicated method.

Interested people can follow these steps to check the install date and time of Windows in Registry Editor:

1. Type regedit in RUN dialog box and press Enter. It'll open Registry Editor.

2. Now go to following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

3. In right-side pane, look for InstallDate DWORD value.

4. This DWORD contains total number of seconds since 1st January 1970. You'll need to perform some mathematics calculations to find out the date and time information from the given number of seconds.

  • Thnaks, very useful commands,
    not found on any other website better than this

  • We can also get the approx. date of installation by looking at programs installed. If we arrange them as per date installed. Any software will be installed only after OS is installed.

  • The November, 2015 update to Windows 10 changed the recorded install date to the date the update was applied. This wipes out the real Windows 10 install date. The approximate real Windows install date can be recovered by looking in the Windows System folder. The earliest file dates will be the install date. I don't know why they did not record the install and update times separately.

  • dear VG,
