I recently D/L this to a flash drive thinking it might be handy sometime. That sometime came yesterday when I discovered that our church secretary had used my office computer while her machine was out for repair. Every program she would have needed was on there but she installed a full data backup of HER computer, installed 2 other printers, AND MS Office 2007. My poor ole Dell with very little memory would barely boot, and then would just sit there so I couldn't get to control panel and certainly couldn't download the installed version of Revo. It took 5 hours of work to get rid of the printers and Office 2007, but Revo did the job and my machine is down to its underwear now, with just what I use. Guess who is changing their password!!
