Many times when Windows users try to run Windows Update or try to access Microsoft update website or try to update Microsoft Security Essentials (MSE), they receive weird error messages like "0x80070424". Windows XP users may also find that Automatic Updates feature is disabled in Security Center and they can't enable it.
Actually it happens when a few system services required to run Windows Update are not running or a few system files are not registered properly. Microsoft has acknowledged the issue in a KB article and provided a fix for it.
Microsoft has also shared a few known methods to fix this annoying issue which are mentioned in a simple and easy to understand language as following:
METHOD 1: Enable the required services
1. Type services.msc in RUN or startmenu search box and press Enter. It'll open Services Manager.
2. Now make sure following services are set to Automatic and running:
- Automatic Updates OR Windows Update
- Background Intelligent Transfer Service
- Workstation

If any or all above mentioned services are not running or not set to Automatic, double-click on the service, set its Startup type to Automatic from the drop-down list, Apply the changes and click on "Start" button to immediately start it.
3. Restart Windows and it should fix the issue.
METHOD 2: Register the required system files
1. Run following commands in RUN or startmenu search box one by one:
regsvr32 Qmgr.dll /s
regsvr32 Qmgrprxy.dll /s
2. Restart Windows and it should fix the issue.
METHOD 3: Run Windows Update troubleshooter
1. Provide following command in RUN or startmenu search box and press Enter:
explorer shell:::{26EE0668-A00A-44D7-9371-BEB064C98683}\0\::{C58C4893-3BE0-4B45-ABB5-A63E4B8C8651}
2. It'll open Troubleshooting page in Control Panel. Now click on "Fix problems with Windows Update" link.

3. It'll launch Windows Update troubleshooter. Follow the instructions and it'll fix the issue.
PS: If you are using Windows XP or Vista, you can download and run Windows Update troubleshooter using this topic.

Kyle

yethz
@Kyle:
That service options will start the service after a few minutes when your windows has restarted..
actually, its a common sense thing. :)

hey VG, whenever I try to update Microsoft Essentials, this error code pops up "0x8024400a".
Can you tell me how to fix this.........
VG
^^ If you are using a firewall, try to disable it and then update MSE. You can also try following hotfix:
support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=923507&kbln=en-us
@Kyle
As yethz said, its used to start a service with some delay to make the whole system startup faster. It lets other startup items launch faster.

Very useful tips. Thanks VG. Best luck.
