I have been unable to maintain system restore in Windows 7. I run Win 7 Ultimate, both 32 and 64 bit on different machines. Everything starts out OK but after some time if I access system restore I get a message that no restore points have been created and that is the end of that. When I go to system configuration I can create a restore point and it will remain for a few reboots but then i get the same message about none being created again. I tried setting the disk space available to about 10 to 40 GB but that doesn't make a difference. I have the same experience on both 32 and 64 bit systems and had the same exprerience with Windows Vista. If someone could point me in the right direction I sure would appreciate it.
