Disable the last access update

Whenever a folder is opened from an NTFS volume on a Windows NT machines, the system takes the time to update a timestamp field on each listed folder, called the last access time. On a heavily used NTFS volume, this can affect performance.

If you'd like to get a little extra performance out of your disk volumes, or if you have a large number of folders, you can disable this process and make directory lists more nimble.

Follow the below steps:
1. Open the Registry Editor (Regedit.exe). Start--> Run--> Regedit.exe
2. Browse to:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem.
3. Look for NtfsDisableLastAccessUpdate.
If it doesn’t exist--> add this DWORD and set its value to 1--> which will disable the process.
4. Close the Registry Editor--> and reboot the computer.

Important: Editing the registry is risky, so make sure you have backup before saving any changes.
