I think that CCleaner is your best bet but you should take a look at this Apple support info at
https://discussions.apple.com/docs/DOC-6562
Read the second box and especially note 2.
What might be a good strategy is to use CCleaner to remove all the Apple software in this order: iTunes, Apple Software Update, Apple Mobil Device Support, iCloud (if present), Mobil Me (if present, nut not likely) Bonjour, and Apple Application Support both 32 and 64 bit. Be sure to back up your music just in case.
Then follow up by looking for and deleting any of the folders noted in the Apple article that might still be present just to be safe.
Since your not going to work on this until Monday maybe some of the other folks could give their opinions.
If this fails to do the trick then you might be looking at a clean reinstall of you old system or Win10 as long as you have of the install media, keys, and above all your data.
