New submitter StirlingArcher writes "I've always built/maintained my parents' PC's, but as Mum has got older her PC seems to develop problems more readily. I would love to switch her to Linux, but she struggles with change and wants to stay with Vista and MS Office. I've done the usual remove Admin rights, use a credible Internet Security package. Is there anything more dramatic that I could do, without changing the way she uses her PC or enforcing a new OS on her again? One idea was to use a Linux OS and then run Vista in a VM, which auto-boots and creates a backup image every so often. Thanks for any help!"
