EEK! Did I break something?

OK, SP2 has installed, comp restarted, chkdsk found no errors...explorer took a dump and crtl-alt-del would not work so I had to reboot...

...and I've now lost my task manager. Unless SP2 renamed it...CTRL-ALT-DEL does not work. I get the hourglass, so it's trying to do something...

WMP will not run at all, nor will my other audio progs.

chill out and reboot...its only explorer.exe

Got it...after a while things sorted themselves out. Seemed to be explorer and the updates; reboots in between updates didn't fix things, but the final reboot did (although explorer barfed on me again this morning following an autoupdate...hmmm there's something weird going on here).
