File deletion on Windows too slow

When manually deleting files during a manual uninstallation, the deletion of the files in the path $TWA_DIR\TWS\stdlist\yyyy.mm.dd\Onnnn.hhmm is unacceptably slow.

Cause and solution:

This problem is caused by a known Microsoft issue on Windows operating systems. It occurs when you try to delete the indicated files on the Windows system after having uninstalled the master domain manager. To prevent the problem from occurring use Shift-Canc to remove these files instead of using the Delete menu option, moving them to the recycle bin, or using the Canc key on the keyboard.
