Thank you Hader but unfortunately I've already tried that solution downloading an ISO from ma official site, but the update fails with an error like "..during MIGRATE_DATA in the SAFE_OS..".

A couple of posts ago I also attached logs of that phase

Be aware; an In-Place-Installment is NOT an update but a special kind of new install.

The error you encountered is a serious one; I had this issue also in Nov 2025 when tried to fix an issue also; The In-Place-Installment failed also with the same error. The cause: "occurs when Windows cannot move user data during an upgrade or update" I searched the internet how to address this issue; Things like remove all USB devices, Disable all programs at startup, and disable all non-Microsoft services. Deinstall the anti-virus program etc. All actions did not fixed this problem. (I had enough space left to hold 2 Windows installations incl. my personal data) The Windows installation was damaged beyond repair; DISM and SFC could not fix the issue also....

Maybe a thing to look at; (If space is an issue) To see this will work; using the cleanmgr.msc to discard all old Windows backup updates. (Clean systemfiles on C:) Looking at it now I don't think that it will solve the issue also. Currently I see some 380Mb of old Windows updates files and is refusing to clean them..... For some reason they are marked as not deletable....

There was only thing left; Make a backup. (I used Hasleo) Wipe the disk clean and start a new 25H2 installation. After that I had a new and fresh installation. I could mount the backup and retrieve all my personal data from that backup. After that made a new backup and threw any previous made backups into the bin. Those were no longer trustworthy. (You can't pinpoint when things were going wrong) Well the most important thing was to secure my personal data. Programs can be re-installed again. With a few hours I was back again with a cleaner windows. I have not seen this error since then. A bummer indeed....

Data is not a big matter since i have all of them on different drive but It's the time wasted on updating something that was working flawlessly on tuesday. Btw I'll try to clean old updates even if i have 100+ Gb free. Today I used the pc and after the first 5/6 mins to make the taskbar appear I could play with my Epic Store account, use Firefox but something is corrupted for sure since I'm unable to open the start menu, certain apps are not working (Whatsapp desktop app says that interfaces isn't registered..).
Yesterday I also tried to "unpack" the image from the downloaded iso with these command but DISM keeps failing

Code:

dism /Mount-Image /ImageFile:"E:\sources\install.wim" /Index:3 /MountDir:"C:\mount" /ReadOnly

It's a shame that a feature like this isn't able to replace corrupted files...

I did not mean any Dism cmd. I meant that specific Dism cmd.
If you ran it whilst you had an internet connection, as the tutorial instructed, then I do not think you will be able to avoid a Clean install.

Hi Denis,
I've followed SFC and DISM guide ofc with always the same error (the source files could not be found) both in powershell and cmd (online and with an ISO downloaded yesterday from ms official site)

It keeps telling me that the image is repairable but, in fact, it is not
Path :
Online : True
ImageHealthState : Repairable
RestartNeeded : False

Try3 · Mar 21, 2026

That does not look like an output of the specific Dism cmd suggested in the SFC tutorial.

It's the first command issued in that guide Denis, in order to check the image health

PS C:\WINDOWS\system32> Repair-WindowsImage -Online -CheckHealth

Path :
Online : True
ImageHealthState : Repairable
RestartNeeded : False

And after that (sorry for italian errors)

PS C:\WINDOWS\system32> Repair-WindowsImage -Online -RestoreHealth

Yes they are
The SFC tutorial points to DISM guide that contains those command. Here in the blue box after point 7 there's a link to the DISM guide with the command I used (the powershell ones of course)

I told you the exact para to read in the SFC tutorial and showed you the dism cmd it suggested.
Your step 7 link suggests the same dism cmd.
Your posts report doing a different dism cmd.

My post is reporting the exact command

Repair-WindowsImage -Online -RestoreHealth -Source "F:\sources\install.wim:1" -LimitAccess

It's the powershell one and not the cmd one.
Btw i'll try to remove my last update since the difference in build version that prevents DISM to work properly

Yes. But this error is a clue that something is definitely wrong under the hood of the Windows engine. You can look away and continue but at a certain point you have to install Windows again. This problem will not go away. I am not sure that we are talking about corrupted files here. You already used the DISM and SFC commands and found nothing. If corruption were the issue, it would delete these files and replace them by downloading them again.

Maybe an inspection a level down is something to check now; you can check your disk first to check if the filesystem on disk does not contain corrupted blocks. When found it can repair them but only until a certain level.
- chkdsk c: /F /R (CMD as admin)
- Files are in use. It will be scheduled to run at the next reboot.
- Reboot
- When done; Eventviewer; look for winint and see if it found any issues. If none; No corrupted blocks in the filesystem has been found.
Already inside the eventviewer; look for strange error messages. It might give you a clue what's wrong. (the chance of it is very low, but who knows....)

The clue "can't move user data" seems to point more to a rights issue. That is a bit strange because the In-Place-installment procedure uses the TrustedInstaller which is the highest user on a Windows system and should have superior rights to move things. Much higher even than as a admin could.
I don't have insight when and who is trying to move the data. I suspect that the procedure wants to move certain things (or migrating) into the Windows.old directory. That's always there after an successful attempt. ((The reason for this failed attempt? Unknown.) TrustedInstaller, a systemuser, Admin?..... Also no clue where to look for which "data" is not movable. It may copy the data but if it can't delete it on the original location it fails. It wants to replace this file by a "older" version. (belonging to 26200.6584; The official MS initial build release of 25H2)

One thing is for certain; your Windows installation is damaged. You may try other things to see if that could fix the issue. The probability that it can't fix it either is very high. You can continue for the time being but there maybe will be a future update that falls over the same problem. And than your stuck again. And you have now that strange taskbar behavior that can't be explained either. Maybe a piece of tweak software is causing this? I don't know. Maybe an link onto the desktop that calls the Taskmanager (C:\Windows\system32\Taskmgr.exe. I would rather use procexp64.exe from the MS SysInternalsSuite to get a deeper dive into the processes and their threads.) and see which process is very busy before the taskbar appears may give you a clue. That delay is a clue that your system is busy with some other process first. The system has to wait until this process has ended before it can show you the taskbar. So what is this process "eating"? CPU-time, Drive-time?.... taking a couple of minutes is indeed a very long time.

I would install Windows fresh. But that's me. You can decide otherwise. (Saw some video's which should "solve" the issue. In my case they did not "solve" anything.)
