Most programs not starting up

[thebladeroden]

I downloaded a Windows Update the other day but then got an error that it didn't install correctly. Soon later my comp suddenly reboots by itself. Then when I log on I can't launch half of my programs. Things like notepad, command prompt, CCleaner, & task manager work. But things like Steam, Internet Explorer, FireFox, games, Notepad++, uninstallers, when you click them, you get the spinning circle for a couple seconds, then it goes back to the normal pointer like nothing ever happened, no processes show up in task manager.

So I tried doing a system restore, but that didn't work. Then I tried the sfc /scannow technique. Then it said there were some corrupted files that couldn't be repaired. I open the CBS log and here's the errors that it had.

I go to the files in question, but I can't do anything with them. When I try changing the permissions on them, I get an "access is denied" even though I'm an administrator. So now what do I do?

I tried doing a repair install of Windows 7, but when the comp restarted I get an error message

winpeshl.exe - Application Error
The application was unable to start correctly (0xc0000142). Click OK to close the application.

Then it restarts and takes me to a new W7-type login screen. Except the profile picture is blank, and there's a username and password field. But no matter what I put in them, I get an error saying "The specified domain either does not exist or could not be contacted." and it takes me back.

Since you've done a repair install, I presume you have a retail Win7 install DVD and not OEM recovery disks?

At this point, I think your best bet is to boot from your install DVD and reinstall over your existing Windows partition. Provided you don't delete any partitions or reformat, you'll lose all your settings and need to reinstall all your software, but you'll keep all your data files.

You could keep messing with this in the hopes of finding a solution but a reinstall is almost certainly quicker and easier.
