I'm hit with this shit too.
Can't open images, volume settings are fvcked, can't even ctrl-alt-delete.
Your previous fix didn't work so give me a step-by-step guide which does, failing which you can expect a lawsuit for punitive damages.
Nah, I had to learn the hard way, so should you.
Some guys seemed to fix the issue by updating their graphic card drivers.
Other issues might be fixed by copying "deleted" dll-files from the windows.old folder and pasting them back to the standard system32 folder, reinstalling various software, reinstalling drivers for deleted printers (or changing deleted default printers to ones that are still installed), uninstalling and installing "Visual C++ Redistributable for Visual Studio 2012" etc etc. The possibilites are endless.
