I have a conputer with windows 7, 64 bit. I have an old program (network magic) that came over with my upgrade from vista. It is not compatible with windows 7 but when I try to delete it I get the message that the program is being used by another program and cannot be deleted. In my old xp computer I had a utility that would delete programs like this when the computer was shut down. I can't find such a program for windows 7. Any suggestions?
