SYMPTOMS
When you run the Windows System Restore utility, the utility may stop running, and all restore points are deleted. When this occurs, the following error is recorded in the system event log:

0xc0000040

In this scenario, the System Restore utility restarts the next time that Windows is started, and new restore points are created.



CAUSE
This issue may occur under a rare set of circumstances -- specifically, when a program or programs try to simultaneously access and modify the same file in a way that creates a conflict with the functions of the System Restore utility.

This issue has been reported in connection with RealOne Player by Real Networks.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
