Hi
If you have more then one partition and don't want to remove your Windows.old file just move it to another location.
To do this copy it to the new location and then use CCleaner to remove it from it's location on Drive C:\. Make a note of where you moved it from, so if necessary you can move it back and run restore.
After the month is up you can just delete it, from where you saved it.
Other temp files you can probably just remove now using CCleaner, that's why they're called temporary. LOL
