most small sw can b done so.. all their needed files 'll 90% b in the Programs Folder... just save those & run the program there... chances r that they'll work. However... registry edits & windows files r needed again.. some sw put some important files in the Windows folders too. That might screw it up again.Just keep tryin.. Find out the favourable guyz & back them up.
Regd.. registry... it's a long way.. u've to save the registry portions of the respective sw (like User names or sw address or settings...)
BTW... that's the trick behind those Portable Applications.... like Portable Firefox..
I'ld ask u to just dl sw from
this site... and use them directly.
