Come to think of it, I arrived here in this thread with an entirely different tale to tell. Customer came in a month or so ago to buy WinXP and have it installed, so that daughter could use her new iPod. No problem, it was a decent machine, added som RAM and away we went.
Came back today. System worked fine until she loaded iTunes. Now can't access the iPod. To my disgust, the Soup Nazi made himself so busy with other jobs that I had to have a go at it myself. Me! Darling, I don't do games, printers, or anything to do with stupid music software. (Waves limp wrist and winces. Or possibly minces.)
Where to start? Take crap out of the startup, I guess. Hello, hello, that looks like a whole stack of spyware to me, along with the typical commercial junk (Realplayer, Quicktime, MSN, the usual suspects). Soon as you see filenames in startup like skjsdjhuirtf.exe you know it's another spyware job.
An hour or so later, Hijackthis, Spybot, and Ad-Aware had done their stuff and the system was vaguely clean. Still no iPod. No sign of an add-remove programs entry for iTunes though. So I went back into safe mode, and brute-force deleted the iTunes folder out of program files. Slipped into Regedit and did a global search and delete for iTunes. Well, did a bit of it, then I ran out of time and just hoped I'd nailed the important bits. Rebooted, and hey presto, the iPod works again.
I told them that they could probably load iTunes again now, seeing as the system is clean, but it would be wise to wait until we re-open in the new year, just in case it stuffs up again. Whole job took me an hour and a half, give or take. Told them no charge, it's Christmas.
(I'll go back to being my usual mercenary self before too long, of course.)
