uncheck wipe freespace in the advanced section. That was not checked! Read on a forum that Ccleaner may be the culprit. I have the idea that somewhere in W7 something fishy whereby after 24 hours the created restore points disappear. The system belongs to create a restore point on a regular basis! Never seen it. Maybe Microsoft has a answer. Thanks for your advices.

If Ccleaner removes the restore points, how can you ensure that Ccleaner no longer removes the restore points?

Concerns restore points Windows 7 Home 32 bit. The created restore points disappear after 24 hours. In Ccleaner via Tools and System Restore I read: Manage all your system restore points (this last is due to system safety disabled) How can i enable it?
