Unable to get File History backup to work with my USB device

BT 0

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.

Hello Emma1-N,

Apologies for my delay getting back to you. I have worked through items 1, 2 and 3 above. I can report:

When I select Turn On is File History, the mouse pointer makes the button go darker, but when clicking on the button it goes dim/goes clear, then after a couple of seconds it reverts to its original state. There's no error message. In File Explorer, the USB drive shows up as (F:). It is formatted to NTFS.

I made sure the File History needs are running. File History startup type was Manual (Trigger Start). I clicked Start and it's running. Windows Search was already running.
Reset File History Configuration - I followed the steps to rename Configuration folder to Configuration_old [I realise now you said to rename to Configuration.old - sorry]. I tried reopening File History but Turn On still wouldn't work. (goes clear/white then reverts to original state).
I then went through the Repair Windows System Files. I ran the DISM /Online /Cleanup-Image /RestoreHealth This took about 1/2 hour to reach 100% - completed successfully. I then ran the sfc /scannow. When verification reached 100% I got message "Windows Resource Protection found corrupt files and successfully repaired them"

I then restarted the PC and tried File History again. File History shows My Passport (F:), and with 1.81 TB free of 1.81 TB. But I still can't turn it on.

Perhaps I should tell you that I started having issues in September - it looked like there were large sections of the File History missing. I tried some remedies myself using CoPilot AI but I think it ended up that File History stopped working altogether - like where I am now. Microsoft Support accessed my PC remotely and reloaded Windows, after that the File History would run. However, I was aware that there were large areas of the history missing, so I thought it would be best to make a clean start. I couldn't find "a user manual" for File History (like- what to do if you want to start over) so I manually deleted the files on the MyPassport and reformatted it. You are allowed to swear and call me stupid.

I think I'm partly the cause of my own misfortunes, but hope you might still be prepared to try and help me out...

I can confirm that File Explorer does recognise the USB device, and can drag a file onto it and open that, I can drag the file back onto my desktop and open it.

As part of previously using AI to try and sort the problem out, I have gone into Device Manager and uninstalled My Passport (F:)

Once again, I'm sorry about the delay in getting back to you, and for probably having been an idiot. I don't necessarily use my PC every day, so please don't feel you have to respond straight away.

Thanks for your time

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.

Hello BT,

I just wanted to check if my previous response addressed your question correctly. If there is anything I may have misunderstood, I would truly appreciate it if you could provide a bit more detail to help me better understand your needs.

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

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.
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.
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.
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.
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.
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.
