After writing my reply to Sandra on this topic, I decided to see what the Windows Disk Cleanup would do on the same machine. This refers to a Vista laptop which I have been using for around 8 months. CCleaner offers to remove just over 800 mb, the Windows Disk Cleanup no less than 5 gb! The list for the latter contains many items which, without some research, mean nothing to me. Is it advisable to use a program like CCleaner in addition to the Windows Disk Cleanup? On XP systems I had always run the Disk cleanup regularly and left it at that. But I have been a little cautious with Vista. Any comments would be much appreciaated, Douglas -- Douglas Harrison
