To make a long story short... I accidentally opened an e-mail attachment I shouldn't have. (I had a "good" reason for doing so.) Wondering if its executable was lurking anywhere, I ran Process Explorer -- and there it was. Two clicks, and it was gone.
I will, of course, double-check the next time I restart.

I had a mighty scare today on my laptop. On booting, everything I tried to do resulted in an error message. I couldn't access msconfig, control panel, the Start/Stop button on the taskbar, System Restore, nothing. Right clicking the Start Menu did nothing. Kept saying something was trying to erase a registry entry or something.
Googling on my old laptop showed that with Win8, you can no longer get into safe mode by pressing F8 whilst booting, is has to be achieved via Windows actually allowing you to do this, and mine wasn't allowing me to do anything at all. Nightmare.
After a lot of perseverance, I finally discovered there is another instance of the Power Button if you press the Windows flaggy button to reveal all the "apps", a feature I never use. Clicking this Power Button whilst holding Shift finally allowed me to access System Restore. Which worked.
I don't know how this happened, I don't think I clicked any dodgy attachment and I don't do any dodgy websites, but I have been caught out in the past, and since learnt to be very suspicious of most things.
The first error message I got was "Windows Live Mail Calendar is corrupted", and Live Mail refused to run. This quickly progressed to the registry error message on everything I then tried to do.
