Now that you've had a chance to let SP1 settle in without hiccups, on the odd chance you were wondering what Windows was doing for half-an-hour when you installed the measly 80MB SP1 update for Windows 7 (assuming you started with an up-to-date installation in the first place - larger, if you didn't), it basically created more backup files than a growing boy's daily allowance calls for.
To clean up all that nonsense (and gain back a GB or two), as described here just open up an elevated command prompt and copy/paste the following deliciously cryptic command:
dism /online /cleanup-image /spsuperseded /hidesp
Windows will chew on that for a few minutes (surprisingly longer than you'd expect), but in the end it will happily clean out all the leftover rubbish - leaving you free to bake a cake for the beleaguered Gaddafi, as lord knows he could use a little sugar-comfort about now.
Win 7 SP1 Cleanup/Succour for Tyrants...

I only gained 1.6 GB, but that's better than nothing. I had completely forgotten about cleaning out this stuff until I did a virus scan yesterday that inexplicably took ten minutes longer than usual - it seems SP1 "backed up" virtually every DLL in the \Windows directory whether it needed to or not (which considering x64 doubles-up all the files anyway, that can add up to "lots and lots").
This was simpler on Vista, as MS included a special cleanup tool for that one. This one's not as obvious - but worth the trouble.
Cupcakes for Mubarak!
