This is probably not the right forum, but I don't know where else to post it (in Tom's Hardware). Anyway, about a year ago, my dad got a new computer from his company because it was time for an upgrade. My dad bought the old computer from them for $5 (for home use), but they had to clear out some valuable corporate information. It has really old hardware with Windows XP Professional Service Pack 1. There is a bunch of software that I don't want (and a lot that I do want). I tried uninstalling the programs from Add or Remove Programs, but I can't. For example, a message would appear like "An error occurred while trying to remove Citrix\CA Client. You do not have access to \UNWISE.EXE. You can specify the new uninstall program below." So I suppose the programs were installed from the companies network. So is there any way to clean up the crapola of files and settings without losing valuable software?
