VideoRedo for example which is a video editor. I can't remember exactly what happened but I installed uninstalled it multiple times and the next time I installed it there was a glitch. That glitch wouldn't have happened if I did a clean install where the program was never installed before.
Don't know what those are. UNIdesk looks really expensive, I'm not a millionaire. You got some more info?
I'd like to use a program that allows me to "install" programs without writing anything to the real registry. So if I want to delete the installation I can do so easily without effecting the real registry.
