I can't get the Windows File History backup (part of the Control Panel) to work with my USB disk drive. I can't "Turn on" file history. There's quite a lot of background to this, but I don't know what information may be relevant and what isn't.

    Welcome BT,

    Thanks for reaching out to Microsoft Q&A Forum. I understand that you're unable to turn on File History in Control Panel with your USB drive on Windows 11.

    To help narrow this down, could you please share:

    • What happens when you select Turn on? For example, is the button greyed out, does nothing happen, or do you see an error message (please share the exact text)?
    • In File Explorer, does the USB drive have a drive letter, and is it formatted as NTFS? To check the format, right-click the drive and select Properties.

    Please make sure you already tried the Q&A Assist steps. In addition, please try the following:

    1, Make sure the services File History needs are running.

    • Press Windows + R, type services.msc and press Enter.
    • Find File History Service. Make sure its Startup type is Manual or Automatic, then right-click it and select Start.
    • Do the same for Windows Search, which File History also depends on.

    2, Reset the File History configuration on the PC.

    • Close Control Panel.
    • Press Windows + R, type %LOCALAPPDATA%\Microsoft\Windows\FileHistory and press Enter.
    • Rename the Configuration folder to Configuration.old.
    • Open Control Panel > System and Security > File History again and try Turn on.

    3, Repair Windows system files.

    • In Terminal (Admin), run DISM /Online /Cleanup-Image /RestoreHealth and wait for it to finish
    • Then run sfc /scannow
    • Restart the PC and try File History again

    Looking forward to your update.

    Try this end-to-end path for File History with a USB drive:

    1. Verify the USB drive is connected and visible in Windows.
      • File History requires an external drive or a network location.
      • If the drive is not being detected reliably, check Device Manager for device errors. If needed, unplug and reconnect it, or test the disk on another PC to determine whether the issue is the disk itself.
    2. Open Control Panel > System and Security > Save backup copies of your files with File History.
      • If no drive is selected, choose Select drive, pick the USB drive, and select OK.
      • Then select Turn on.
    3. If File History says the drive was disconnected or asks to reconnect it:
      • Make sure the USB drive is physically connected.
      • In Control Panel > System and Security > File History, reselect the drive.
      • After reconnecting, wait for the next scheduled backup, or select Run now to start one manually.
    4. If File History still will not turn on, check for a conflict with the older Windows Backup schedule.
      • File History does not allow itself to be turned on if an active Backup and Restore schedule exists.
    5. If this started after the September 2026 Windows updates and the USB drive is connected but File History still shows a reconnect message or the Turn on button does nothing:
      • This is a known issue affecting File History.
      • Install the latest Windows update. Microsoft states the issue is resolved in updates released on and after September 22, 2026, such as KB5124010.
    6. If the USB drive appears but still behaves inconsistently, test basic hardware detection:
      • In Device Manager, look for warning icons on the USB or disk device.
      • A common recovery step is to right-click the problematic device, select Uninstall device, then select Action > Scan for hardware changes.
      • Caution: this changes device detection state and should only be used if the drive is not being recognized correctly.

    File History backs up personal files such as Documents, Pictures, Videos, and Desktop to an external drive or network location. Additional folders can be included by adding them to a library.
