Suddenly Windows 7 has stopped installing Windows Updates. It downloads, then creates restore point, starts installation, but then comes back with the error code 800F0900. This happens with all the updates when carried out individually, critical or optional. I first went through the process of clearing all the Start-up Programs in the Services section of msconfig. As that did not solve it I then stopped all but MS services, and that did not solve it.  I tried the Microsoft .NET Setup Verification Tool. This said there were problems that it could not fix and sent a report to Microsoft.  Following an earlier thread on this site, I installed and used the Windows Repair program from Tweeking.com. This failed to solve the problem. Does any one have any other possible advice to help solve this problem ?

I would try running the System Update Readiness Tool:  http://www.microsoft.com/en-us/download/details.aspx?id=20858 .

Use my batch script to reset Windows Update components then check to see if issue has been resolved.

Hi hamluis,

I have already tried the "System Update Readiness Too"l, just forgot to list it as one of the optioned tried. Obviously it did not work; otherwise would not have been posting the query.  Thanks anyway.


Hi Freebooter,

Have just tried your" Reset Windows Update Components" program, but did not work. Thanks anyway.
