OS is Windows XP Sevice Pack 2 Home Edition. Frequently, I download and tryout freeware programs. The files for these software downloads typically become located in one of three locations on my PC -- Control Panel Add/Remove Programs, My Documents, and C: Programs. Often while executing remove, erase and/or delete to uninstall every single file for these programs, my OS refuses to uninstall one or more of the files of that program. What can I do to uninstall a software program's files that XP refuses to let me remove, erase or delete?
