SYMPTOMS

When you do either of the following on a computer that is running Microsoft Windows Server 2003 or Microsoft Windows XP, you may experience an unexpected increase in the number of registry key handles, process handles, and thread handles that remain open:
  • You use the Automated System Recovery (ASR) feature of the Windows Backup tool.
  • You use a program or a service that calls the AsrCreateStateFileW function.
These open handles may eventually cause the performance of your computer to decrease.

CAUSE

This problem occurs if the EnumerateInstanceKeys function opens a registry key and then does not close the registry key that is currently open before it opens another registry key,
