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.
First :Back up your registry - Back up tools here
Open the registry - Start > Run and type regedit
Navigate to Here : HKEY_LOCAL_MACHINE//System//CurrentControlSet//Control//fileSystem
Create a new key called NtfsDisableLastAccessUpdate by right clicking in the right window , and choosing New > DWORD Value.
Once that key is created, double click on it and change the value from 0 to 1
Reboot and enjoy the speed
Or just download the registry entry file, unzip and right click - choose merge.
