Please help me out....

The logs shows one update as missing (20c90741-ca52-46d3-810c-0343e320152b).  This is listed in the file as a security update.  A couple of lines below we can see the same update finished installing, but the code 0x800b0100 is shown.  Perhaps the following article would be helpful in identifying the issue.

If the issue in the article is not helpful, can you install the update in the machine from Windows Update?  Or manually?  What results do you get then?

I found in some of the sites, WMI repair will solve this problem, but i'm not finding proper diagnoses tool for windows 8, if you found the solution for this, please share with us

Thanks in Advance
