What Categories in Registry cleaner are safe to delete from?

Hi I use Windows vista sp1 and latest CSC I was just wondering what categories in registry cleaner are safe to delete from.

All except “Unsafe to delete” should be safe to delete (there are no guarantees).

You might be interested in the latest CSC/CRC Beta version, where you are offered to reboot, check if everything works etc. before you finally let CRC delete the suggested entries.
