My brother stumbled on this disturbing item which caused a number of others to chime in that this apparently is not an unusual problem.

I did a clean install of Win7 about 3 1/2 weeks ago and have had no problems. 2 days ago I discovered that no system restore points were available. After spending many hours researching the issue, I’ve taken the following steps but none have helped:

1. Completely uninstalled AVG and installed Microsoft Security Essentials.
2. Tried turning off System Restore, rebooting, turning it back on.
3. Checked the SR schedule in Task Scheduler, all seems fine. It creates restore points just fine, it just won’t keep them on reboot.
4. Scanned computer thoroughly with three different anti-malware programs, no problems found.
5. Did a sfc /scannnow, no problems reported.

One guy contacted Microsoft with this rather bizarre answer and (not unexpected) request for money to research their problem:

Microsoft thought this might have something to do with my domain it but would not troubleshoot it for me without paying the fee, which I cannot afford.
