I was helping my sister with her laptop running Windows 7, which was not able to uninstall anything from Programs & Features. I could use all applications fine, but when I tried to uninstall a program it stated the Windows Installer Service was not running. I checked the running services and saw that it was though. I then noted there were 83 Windows Updates available, so I decided maybe I should do all those updates and see if they resolved the problem.
After installing the 83 updates and restarting, about ten of them failed...and now I cannot run any exe files on the laptop. The remaining updates repeatedly fail if I try them again as well. It gives the following error when any program tries to run (aside from notepad, which seems to be the only thing working still):
I researched the error and found a ton of pages saying that the update KB2859537 causes this error and to uninstall it, but that isn't even an installed update or one that was in the 83. Perhaps a different update causes the same issue or the laptop is infected in some way? I get the same error even after booting into safe mode. Any help?
Oh, and I already tried system restore to before installing the updates. It just caused a BSOD on boot and I had to system restore back to after having installed them again. File association fixes did not resolve the problem either.
