I keep my old computer in my daughters room, and instead of cleaning the files, about once a year, when it starts to act like a jar of molassis on a cold day I reformat.

Much faster. Just leave it alone all year long, then spend one rainy afternoon in front of it reinstalling windows.
NOBODY gets on my computer but me and my wife. She downloads music and puts it wherever she wants.

I say yes dear, no trouble.
