Data loss after Windows 11 25H2 update
Hi everyone,
Since the update of Windows 11, version 25H2, I have noticed data loss and file corruption on my system. Some of my files have vanished, while others fail to open.
Are you experiencing issues like me related to the loss of data after this latest update, and have you been able to recover or resolve this problem yourself?

Thanks for checking in.
I first tried the organic options, but unfortunately, they didn’t work. As suggested by SAPOP, I then used Stellar Data Recovery, and it seems to be working.
The scan is still in progress, so I’m hoping for the best and will update you once it’s completed.
Hi Nina,
Sorry to hear you’re dealing with this — that’s a stressful situation. Were you able to recover any of the missing or corrupted files yet? If so, I’d be interested to know what worked for you (backup restore, Windows recovery options, or something else).
This makes sense. After trying a bunch of fixes with no luck, I ended up using a data recovery tool and was actually able to get my file back. Here’s the one I used: https://apps.microsoft.com/detail/9pm3tvx83ddm?hl=en-US&gl=IN
A heads-up for everyone here, the January 2026 Windows 11 updates caused serious stability bugs – some PCs couldn’t shut down, hibernate, or even log in remotely – forcing Microsoft to release emergency out-of-band patches for 25H2 and other versions. These rollout problems might help explain some of the data loss/instability reports people are seeing.
25H2 has been messy for a lot of people, especially with file indexing and USB instability. If rollback is gone and system tools failed, stop writing to the drive and try a reliable data recovery software before things get overwritten.
Yeah!!
I updated to Windows 11 25H2 as well and found a few files missing and some folders behaving oddly later. I have not found a clear solution yet, but running disk checks. Would be interested to know if anyone managed to recover their files or identify the exact cause.
Dude, I’m right there with you in the same boat with 25H2 after that January patch it’s a complete nightmare! The major problems I’m having are as follows: random restarts have deleted 3 days’ worth of work files, my Documents folder is listed as 0KB (files are there but won’t open), my USB drives are constantly disconnecting during file transfer, and Explorer is freezing every 10 minutes when trying to access the corrupted folders.
What I’ve attempted (and largely failed at):
chkdsk C: /f /r took 6 hours, detected bad sectors but couldn’t recover anything
The System Restore points were all gone after the update
Rollback option grayed out (past 10 days)
SFC /scannow and DISM continue to fail with “source files corrupted” errors
This KB5074109 update just plain broke file system integrity for me. Anyone else experiencing USB detection failure + Explorer crashes? What build are you on exactly? (Win+R > winver)
Complete productivity killer—fixes needed ASAP!
I lost around 10–15 GB of photos. The folders are still there but the files inside are gone. Checked Recycle Bin, Previous Versions — nothing. This update seems risky.
Yes, same issue here. Right after the 25H2 update, some folders were empty and a few Excel files became unreadable. At first I thought it was an update glitch, but looks like many are affected.
