JSI Tip 0213 - A tweak for NTFS performance.

Aug. 1, 1997 Jerold Schulman | Windows IT Pro

When Windows NT lists a directory (Explorer, DIR command, etc.) on an NTFS volume, it updates the LastAccess time stamp on each directory it detects. If there are a very large number of directories, this could effect performance. A new registry entry allows you to control this behavior. Edit:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem

Add Value name NtfsDisableLastAccessUpdate of type REG_DWORD. Set it to 1 to prevent the LastAccess time stamp from being updated.
