Ok so all the settings in CCleaner are now set the way they should be to allow the Recent Documents & programs lists to fill up again, but I think that that's irrelevant because I haven't run CCleaner for a while. The point is that the recent programs & docs do not refill no matter how many restarts. Have checked all of the aforementioned registry keys and nothing unusual is there.
Tried also the trick of changing to 10 programs, clear list & restart but only difference was a larger empty space on the start menu - no recently used programs regardless of what I start. Any other ideas why my Windows WILL NOT fill up the Recent Docs & Programs?
Thanks very much for all your assistance
