STATUS

MORE INFORMATION

This fix optionally forces the file system to explicitly update the file times. By default, the behavior to explicitly set the file times is turned off. To turn on this behavior so that you can make sure that the problem is fixed, you must explicitly create a new DWORD registry value. To do this, follow these steps:
  1. Create a new DWORD registry value and then name the DWORD registry value as follows:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NfsSvr\ Parameters\ExplicitUpdateFileTimes
  2. Set the DWORD registry value to 1.
