Unable to run SFCscan,Windows Updates error 80004002,IE,Troubleshooter

Hmm That's clear - I was hoping that it would find something that would trigger a repair.
I think the pending file that you found was simply the initial installation file, which the system keeps as a backup.

I am NOT an expert at reading the windowsupdate.log file - but it seems to me that the likely cause of the problem is this....

Code:

2013-05-05 15:26:04:811  960 17f4 Setup Evaluating applicability of setup package "WUClient-SelfUpdate-ActiveX~31bf3856ad364e35~amd64~~7.6.7600.256"

If that is the case, then I would have expected CheckSUR to spot it - but it is a fairly limited tool in its way.

The problem is that without some assistance from such tools, it's very difficult to pin down this error and attempt to fix it in a meaningful way.

Please run the following commands, and post the results.

Code:

Oh, b&gg$r!

That almost certainly means that the only option left is a repair install
