anything important stays away from the windows partiton
if you get a virus and need to reinstall or your windows plays up and you need to reinstall or even if its feeling sluggish after a couple of years of use.....would you really want to try and remember everything of importance on C: ? where it is and in what folder.
i could quite safely wipe my C: and reinstall windows knowing the only real loss would be anything that i downloaded or created in the last couple of days.
i think he means in the case of this pc the OP is fixing. sure it would probably benifit most of us here, but the impresison i get from the OP and the users of this PC is that they're not going to care about partitions and will just install stuff in the default location on C with windows, meaning half the programs will be on this partition, the rest will be with windows
