Get Windows Update Error 800B0100

If you get Error codes as following:

WindowsUpdate_800B0100 or 0x800B0100

Try this:

1.Click start Button --> Control Panel --> System and Security --> System, To View basic information of your computer: such as my Windows edition is " Windows 7 Ultimate"

2..Go to the System Update Readiness Tool webpage:

Download System Update Readiness Tool for Windows 7
The tool can prevent you from installing Windows 7 updates.

Its installation is: C:\Windows\Logs\CBS and recording file calls CheckSUR.log.

3.Run Windows Update again.
