    How to Enable or Disable NTFS Last Access Time Stamp Updates in Windows 10


    The Last Access Time stamp displays an updated time each file and folder on a NTFS volume was last accessed.

    In the System Managed mode, the NTFS driver can enable or disable the “Last Access” updates during the boot (in particular, when the system volume is mounted). The “Last Access” updates are enabled for NTFS volumes when the size of the system volume (which is usually mounted as the “C:” drive) is 128 GB or less. If the system volume is larger, then the “Last Access” updates are disabled.

    In the User Managed mode, the status of the “Last Access” updates isn’t modified by the system during the boot. "Last Access" will stay enabled or disabled as you set.

    Value Description
    0 User Managed, Last Access Time Updates Enabled
    1 User Managed, Last Access Time Updates Disabled
    2 (default) System Managed, Last Access Time Updates Enabled
    3 System Managed, Last Access Time Updates Disabled

    Trying to optimize an SSD by disabling this feature. Have tried both user and system options in cmd, powershell and registry, but on reboot it always reverts to ....002, system enabled. What am I missing?

    Hello Margaret, and welcome to Ten Forums.

    I'm seeing the same issue on my system, but I'm not sure why the value is automatically getting reset back to its default 2 on restart.

    Thanks for the quick response. My guess (since your original post was a year ago) is one of the Windows updates since then has disabled user control. I even tried resetting registry in ControlSet for NTFSdisablelastaccess which is for servers but it also reset to 2 on reboot.

    It seems like 0+1 and 2+3 are switched.
    I had NtfsDisableLastAccessUpdate set to 80000001 but I noticed that the times were still being updated, so I ran fsutil behavior set disablelastaccess 1 and it wrote DisableLastAccess = 1 (User Managed, Enabled), then I ran disablelastaccess 0 which said (User Managed, Disabled)

    Hello Guy,

    I doubled checked everything in the tutorial to see if a mistake may have been made somewhere, but it all checks out.

    Just to verify, did you restart the computer to apply and changes to the setting?

    Ok I just did and it still updates the access time so I'm not sure what's going on.
    When I write fsutil behavior set disablelastaccess it outputs the same table as in your instructions but when I enter the specific set number it reports the opposite. I'll try and figure this out..

    Also run the fsutil behavior query disablelastaccess command to see what it reports the current setting is after you change it to see if it matches.

    I also wondered why the behavior on two systems was exactly inverted and found that the values and their meaning really seem to have switched:
    System 1 (Windows 10 Enterprise 1903) where the last access time is NOT stored:
    Code:
    >fsutil behavior query disablelastaccess
DisableLastAccess = 2  (System Managed, Disabled)

Registry value of NtfsDisableLastAccessUpdate is 0x80000002
    System 2 (Windows 10 Enterprise 1909) where the last access time is stored:
    Code:
    >fsutil behavior query disablelastaccess
DisableLastAccess = 3  (System Managed, Enabled)

Registry value of NtfsDisableLastAccessUpdate is 0x80000003
    I have found explanations for the registry values also on other sites where it also is inverted and really wondered why it behaves completely different for me. But since others observed the same thing it really seems to have changed.

    Hello @versat, and welcome to Ten Forums.

    That is odd since the last access time hasn't been tracked in Windows for quite some time now.

    I can only assume that it may have been enabled at some point, or something about it being an Enterprise edition.
