Pretty simple eh?
In Registry Editor, expand the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
On the File menu, click Export.
NOTE: In Microsoft Windows 2000, click Export Registry File from the Registry menu.
In the File name text box, type: "Session Manager Key" (without the quotation marks)
In the right-pane of the Registry Editor window, right-click PendingFileRenameOperations. On the shortcut menu that appears, click Delete.
In the Confirm Value Delete message dialog box that appears, click Yes.
On the File menu, click Exit.
Reboot that sucker and come back and try again....Keep in mind you dinking around with the registry...This gives you a backup of the key but your still playing with fire if you don't know what your doing. Pretty safe change to be real about it...
Bonus plan, if the reg setting continues to come back just smoke it and done reboot and launch the sqlpatch. Should work just as well....my ideas allway work some of the time.
