YMMV, but I've been using Ccleaner and another one (Eusing) for a number of years with no issues, on XP and 7. Not necessary every day or week, once a month is more than enough or after uninstalling something.
The main thing both do is delete redundant entries, which I find speeds up bootup and shutdown times if they start to get long.
Ccleaner is worth having for other reasons too, cleans out temp files, old restore points, gives a one-step list of programs with one-click uninstall, etc.
