WARNING to other readers: These fixes absolutely must not be run on any other computer. They may cause severe damage, and it's only because I've seen the logfiles from this computer that I am running them at all.
First, restart your computer (this step is
absolutely essential, do not omit it), then start an Elevated Command Prompt:
