SYMPTOMS
If you configure programs to run when you log on by using the Run registry key or Startup group, the programs may not run.



CAUSE
When you run a program, such as Microsoft Windows Media Player or Phone Dialer, the Telephony service (Tapisrv.exe) is used. The Telephony service opens the HKEY_CURRENT_USER registry hive and keeps the handle to this hive open for a specific amount of time, even after you quit the program and log off. Therefore, when you log off, the Winlogon.exe program cannot unload the current user registry hive because there is an open handle to it through the Telephony service.



RESOLUTION
A supported fix that corrects this problem is now available from Microsoft. For additional information about this fix, click the article number below to view the article in the Microsoft Knowledge Base:
