I installed a couple of updates and now my computer won't shut down or install certain updates I thought it might just need some time so have left it while going to bed and it is still stuck on the same update when i get up. So i have tried booting it up in safe mode and a system restore but the same problem still occurs. I have also tried Control Panel\All Control Panel Items\Troubleshooting\Fix problems with windows update, which then says the problem is fixed but updates are still failing to install.
For visual studio service pack 1 update it freezes around half way through instillation. And the same problem occurs with the update for microsoft visual studio 2010 tools for office runtime (kb2796590)
Found out in the end after more update not installing and a couple of programs failing to install it was a problem with the "InstallShield Wizard". Which the only way I was able to fix was through a clean install.
