POSSIBLE Bug in CCleaner since February, 2011

CCleaner for Windows CCleaner Windows Bug Reporting
1

I noticed that my System Restore points have been getting deleted at seemingly random times since last February. The Event viewer shows a message that the SR service had been suspended due to a lack of disk space (<200 MB free). This made no sense since I have 91GB free on the drive. The irritating part is, as many people probably know, is that when your System Restore is suspended by the OS, ALL your previous restore points are deleted and you are left with pretty much nothing.

I searched in vain for an answer at Microsoft and on various tech support sites. MS have a few KB articles about this problem, but none of the causes fit my circumstances as there was no shortage of disk space.

Today, just after running CCleaner, I opened the Event Viewer and discovered that my SR Suspend problem had occured one minute before, in other words just after running CCleaner. I recreated a restore point, ran CC again, and blew away my new restore point again. I recreated it again, then I unchecked all the items except for Temp files and Cookies, on both IE and Firefox, then ran CC again, and low and behold, the SR service was not suspened this time.

I have not had time to go through a systematic test of each of the items on the list to find out exactly which one was trashing my System Restore files. I might get to that next week.

Has anybody else run into this problem? Do the Piriform people know about it? Does anybody know which of the items on the list MIGHT be triggering the SR Suspend (I ask in hopes that somebody has already found the answer that I have to look for next week, and will save me the trouble of reinventing that particular wheel)?

Is it possible that the 91 GB free space you see AFTER the loss of Restore Points could include 91.8 GB of the Restore Points that the O.S. has just deleted ?

What version of Windows ?

What Malware protection ?

Are you using the default settings for file cleaning, or have you checked additional items or secure deletion ?

Are you Wiping Free Space ?

Are you cleaning the registry ?

Is it possible that the 91 GB free space you see AFTER the loss of Restore Points could include 91.8 GB of the Restore Points that the O.S. has just deleted ? No, this is not the chase. It is a 120GB drive partition and average free space is 90-92 GB.. I am ruthless in not keeping unnecessary software and data files. There are three other partitions, each 120 GB, roughly the same amount of freespace on each,.

What version of Windows ? XP Pro, SP3 All up to date patches etc.

What Malware protection ? Webroot Spy sweeper running in realtime, Malware bytes (scan only, not running realtime)

Are you using the default settings for file cleaning, or have you checked additional items or secure deletion ? A few extra options were checked, now unchecked, and problem seems to have gone away. Not using secure deletion function.

Are you Wiping Free Space ? Ocasionally. but not on a regular basis. The drives are regularly defragged.

Are you cleaning the registry ? Yes, but not using CC for that function.

I believe Defragging or Wiping Free Space may result in the Operating system deciding to create restore points until it hits a limit and starts again by wiping them out.

Anti-malware software can interfere and cause problems.

What Firewall protection do you have ?

Some Registry Cleaners do more harm than good, what do you use ?

I have no advice to offer but hopefully your answers will inform others who can assist you.
