When I try to run File history it indicate there is no available FHJ drive.
I have done various troubleshooting:
%LocalAppData%\Microsoft\Windows\FileHistory
I reset FH by renaming the Configuration and the Data folder to Configuration.old and Data. to Data.old
I had no need for the backup folders on my Network drive, so I deleted them in order to do a clean up for a new backup.
When I have selected the backup drive (NAS Server wired to the Router) and accepted the BitLocker must, I perform a Run Now just to get this error message, instantly:
"File History. Your files will be temporary copied to your hard drive until you reconnect your File History drive and run a backup"
That I can do in eternity.
PS. I can see that FH has generated the backup folders on my Network Drive, but they are empty, of course.
I have run out of possible solutions, so please help. BTW. The Network Drive is working fine and accessible from Windows Explorer.
I don't understand why I get this error, all of a sudden.
I need your help.
Thanks, Anders
I have come so far, that 2026-09 Security Update (KB5124008) (26200.9445) is causing all the trouble. I uninstalled it on my wife's laptop and File History could again be configured and now works just as it should.
On this my own laptop (identical to my wife's) the 2026-09 Security Update (KB5124008) (26200.9445) cannot be uninstalled. It is not in the list of updates to uninstall. I followed an advice to open an elevated CMD prompt and ran wusa /uninstall /KB:5124008. I got this error message:
This makes no sense at all. I need to get this horrible security update uninstalled to get my File History up running again. How can this be done?
Thanks.

I uninstalled the 9/15/2026 (KB5129195)(26200.9457), once that was uninstalled the 9/9/2026 (KB5124008)(26200.9445) was available to uninstall.

Two culprits: Security Update from 9/9, (KB5124008)(26200.9445) and (KB5129195)(26200.9457) installed on 9/15 are causing the issue.

I have the same problem. The same external drive I've used for File History for a long time is suddently not recognised. Bought a brand new drive. Also not recognised. Not I found this thread... I'm not a tech person so I'm not sure I can remove the updates and then prevent them coming back too...
Especially infuriating as my laptop got knocked a few days ago and need to go to repair and I MUST get a File History backup working!
Indeed I have managed to remove Update KB5124008 and File History is working again. Bingo!
At least until I run out of allowed update pause time. Not sure how else I can stop the updates - what was mentioned above was a bit beyond me.

Anders, thanks for the Microsoft wushowhide tool download link. I'll give it a try.
Two answers have been deleted, due to a violation of code of conduct (??)
I don't understand what that is, but I still need someone to come forward at help me solve the problem.
I just discovered that my wife has the very same problem on her Laptop. Exactly the same problen. I wonder what might have caused it because her FH worked and backed up on the 9/9 - this is just three days ago!
It is a mystery!
Hello Horace,
It looks just similar but when I clock okay I get this nasty message. I checked my wifes laptop. It is identical to mine and FH does not work here either. It worked well on 9/9 - three days ago.
All this is odd. I assume a Windows update messed something up or something similar....It worked FINE three days ago!
Have you gone to, Control Panel>All Control Panel Items>File History? What does that show? If you deleted your folders/files, then they are probably gone. Have you checked your Recycle Bin?
I have two drives on my desktop computer. My C drive is my OS drive, and my file history is saved on my E drive Data.
