Windows Update - won't install SP1 and other updates- error 0x80071a90
Hello
I am struggling to make my windows update run properly.
There are 3 important updates that I cant make it work, they are:
1- 2 of them concerning .NET framework 4 (KB2742595 and KB2789642)
2- Service Pack 1 (KB976932)
For the .NET framework 4 updates: windows actually do update them and says they are sucessfully updated, but when I check for updates again, they are still there. The SP1 is a little different, it does install normally, but when PC logs off to continue installation, it never goes through 14%. Then it restarts, says failure and it rolls back, aborting the update, so when I check windows updates again, if shows SP1 failure, error 0x80071a90.
I've tried many different things, like manual update, safe mode or clean startup config, none work.
Also, I downloaded SURT and installed it, but it seems nothing really happened.
Following Windows Update Posting Instructions
1- installed SURT, but seems nothing happened
2- SFC scan is normal; error-checking tool is also ok.
3- No errors appear on that screen. I will only find the error code for SP1 if I click on "View update history"
4- CBS.zip attached
Any help will be greatly appreciated.
EDIT = couldn't attach zip file because it's size is 20mb.
