NtfsDisableLastAccessUpdate

HKLM\SYSTEM\CurrentControlSet\Control\FileSystem

Data type Range Default value

REG_DWORD

0 | 1

0

Description

Specifies whether NTFS updates the last-accessed timestamp of a file when that file is opened.

Because updating the last-accessed timestamp requires writing data to the disk, an activity that accesses many files might be faster if this type of update is disabled. However, some applications may require that files have an accurate last-accessed timestamp.

Value Meaning

0

NTFS updates the last-accessed timestamp of a file whenever that file is opened.

1

NTFS does not update the last-access timestamp of a file when that file is opened.

This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
