So basically it's cumulative, each newer point relying on data stored in older points rather than needlessly duplicating it, and I would have seen different results if I'd cleaned several points rather than one. That explains why my results were almost the same - one point means no accumulation to speak of, and also why Disc Cleaner can delete the whole lot - there's no reason for it to leave data pertinent to older restore points if it's deleting them too.

Okay, I got curious and/or was bored and felt like wasting a few minutes. I've been playing around creating and deleting restore points... Disc Cleanup removed a smidgin under 18.1 megabytes, and CCleaner a tad under 17.9 (both removing only one restore point), so there's not much in it at all. S'pose I'll have to find something constructive to do now...

I've deleted 'em since, but next time I have a few I'll try that, in a spirit of inquiry - it's always good to know these things.

Ah yes. Good point, well made.

It's there now, though it took about 10 or 12 hours to appear, and several system-restarts. In the meantime I've discovered a few Windows services disabled that shouldn't have been, so it's quite possibly related to that, and my problem - not Ccleaner's. It's hardly the most important module of the program anyway, but if anyone else is having the same problem, please be aware that you can do the same thing manually by running Start/Programs/Accessories/System Tools/Disc Cleanup. When it has finished loading (may take a while), go to the More Options tab and there's an option to remove all but the last restore point there. Thanks for replying Ishi

I installed the latest version (2.28) and there are no system restore points showing in the list System Restore module of CCleaner. I checked via the windows interface, and there are several points in existence. I'm on XP Home edition SP3, if that makes a diference.
