I needed to perform a system restore and found that the restore points only went back 14 days (even when I selected "show more restore points"). Has Ccleaner wiped old restore points and if so, how do I protect restore points from deletion? - Even if CCleaner wasn't the culprit.
Thanks in advance for any assistance or advice.

Did youj have wipe free space checked off?
ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION
DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF.
Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark)
ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.

No - I've never opted for Wipe free space just in case it "diddled" my HDD...

PS - just leaving the computer for a couple of hours or so. If anyone posts a reply and I don't respond, please don't think I'm ignoring you.

By default, Sys Restore uses 15% of the volume's space (in Vista). If it exceeds that, older points are deleted.

It also matters what defrag software you use for instance some will cause Windows to dump Restore Points.

If you want a way to always have a known good daily registry backup you can restore from if/when System Restore fails to undo changes look into ERUNT (freeware).

Piriform software help documentation is available at: http://www.piriform.com/docs

 

Don't PM me for advice! I'll only ask you to read forum rule #15.

Just a bit more info, FWIW [For what it's worth]

The automatic setting of System Restore points is, as pointed out, limited by the amount of space the computer has been set for. I have seen some systems with as little as 5% allocated, some with as much as 20%.

When this protected (and hidden as 'System Volume Information' in the Explorer directory list) space gets filled up with Windows automatic Restore Points, it will deleted/remove the oldest one(s) in order to make room for the new one to be created. So it is a rolling history. It does not count days, per se, but keeps only as many of the most recent as its allocated space allows. And it will generally create one per day, or per startup. And some program updates and installs will force a Restore Point.

Re. suggestion to use ERUNT - Yes, I also recommend this, especially for Windows XP users.
But, as the ERUNT docs point out, because of differences in Vista/W7, you have to lower the UAC protection level to get ERUNT to work properly. See their FAQ for details ERUNT FAQ link.

So the end point from me is:
A) if you have enough free hard drive space, increase your Restore Point storage to some amount which gives you the length of history you wish. Make small changes only and then check. And in general, do not allocate more than 20%.
B ) Note that you should always be maintaining at least about 15% free disk space. So if your Restore Point storage is small because you have too little hard drive free space, Best to move some user data files off and create more free space.
C) note that, once the old points have rolled off, they really are gone.
D) unless you are a technically knowledgeable user, there may be value in keeping UAC at its default middle value. As turning it off defeats the protection that Microsoft believes you need. You have to make your own choice on that one.

Hope this helps. Admittedly, Restore Point discussion is a bit arcane, especially for the non technical.
