Nothing invasive with that.

Otherwise, you would need a location for the Source of the RestoreHealth.
That could be more complicated than a Repair install.

This error message means that your Windows system is trying to repair a corrupted file or feature, but it can't find the necessary files to do so; you need to manually specify the location of a Windows installation source, like a bootable USB or a mounted ISO image, to provide the missing files for the repair process.

What to do:

Mount a Windows Installation Media:
- Download a Windows ISO file that matches your current Windows version.
- Mount the ISO using your file explorer.
- Note the drive letter assigned to the mounted ISO.
- Open Command Prompt as administrator.
- Run the following command, replacing "X" with the drive letter of your mounted ISO:

Code

dism /Online /Cleanup-Image /RestoreHealth /Source:WIM:X:\Sources\Install.wim:1 /LimitAccess

Key points about the error message:

"Source files could not be found":
Indicates that the system cannot locate the required files to perform the repair.
"Use the 'Source' option":
Tells you to add the /Source parameter to your DISM command to specify the location of the installation files.
"Configure a Windows Repair Source":
Provides a link to Microsoft documentation on how to set up a repair source for Windows.

I could just create an ISO of .3025 and point to it. That would be the easiest route for me.
I guess I was more curious why it needs that and couldn't just grab the packages from WU.

Office Version 2502 (Build 18516.20000) is crashing with this RP. I uninstalled 26100.3025 Windows update and office is working fine.

Odd, no issues on my side.

ChrisP · Jan 23, 2025

I have made several attempts to download the ISO for Windows 11 26100.3025 (24H2) from the UUDump site, carefully using the instructions.

The result each time is merely an 8KB file called 26100.3025_amd64_en-us_multi_8cb661e7_convert.zip. The zip contains a number of tiny files.

What am I doing wrong?

I.M.O. It is much easier to do a Repair install.
Your choice.

Unzip the file to a suitable folder location.
Double click the "uup_download_windows.cmd" file in that folder
Click "more info" in the Windows protection window that opens
and click "run anyway"
A command prompt window should open - choose the "Run once" option and watch the files download.........

I used the Repair version and it worked great. Best way to go. And doesn't take long.

Hello, today I installed Windows 11 with update 26100.3025, unfortunately there are still no pinned applications in the start menu, there are only 3 as you can see, I don't know what's going on, is it my computer's fault or is it Windows' fault, and in your opinion, what could it be?

Woooo boy! You CAN fix this without a restore. The bad news? It's a bit technical. First you will need to create an ISO via UUP of 10.0.26100.3025.

I would suggest creating one via UUP that JUST has the single image of HOME or PRO. Whichever you use. It'll make what's to come a bit easier. (see below)

chose one.

Also don't use "ESD compression" when creating it.

Now that you have your ISO you need to mount it by double clicking on the ISO

This will tell windows to create a virtual drive and mount the ISO as if you just put in a USB drive like so

Now you are ready to use the following command to tell windows to run DISM RESTOREHEALTH from a specific path using a specific image. Open a elevated command prompt and type the following command:

The command (using the above example drive) is:

Code:

dism /online /cleanup-image /restorehealth /Source:WIM:<drive letter>:\sources\Install.wim:1 /limitaccess

Change the drive letter to the path that your mounted your ISO. In the example it is mounted to drive G so the command would be:

Code:

dism /online /cleanup-image /restorehealth /Source:WIM:G:\sources\Install.wim:1 /limitaccess

That's it! If you're able to follow all of that it WILL work. I've used this MANY times to correct this very situation.

If you need any help please DM me and I'll do my best, best of luck to you my friend!

It takes just as long to download UUP Dump, or more, than to download and install repair version. Don't you think? And it saves the un technical guy all the tecnacalities.

Actually this is why I always have a current ISO available. There are MANY paths to a solution my friend. I simply offered him one among them. I'm not saying this is the only solution. But in my past experience this has been the best for me. The command itself and the restore takes about 4 minutes to finish. About the same time a normal "restorehealth" takes.

And to download UUP Dump? It all adds up from start to finish.

I simply offered help when it was requested. Nothing more. There is a reason this command exists.

spectrumfox · Jan 23, 2025

Thank you for everyone for all the helpful suggestions.

I went the UUP/ISO/DISM route, as that's what felt more comfortable.

it didn't help it's still the same

Oh no! This wasn't for your particular problem my friend. That was for spectrumfox. But in your case a "in place" upgrade may work. Simply start the install from the ISO under windows and choose "keep personal files and apps." You will NOT lose any settings or programs. This simply overlays your existing installation of windows. Nothing else.

Hope this helps!

You could also try re-registering all the windows apps by issuing this command (copy/paste) from an administrator command prompt:

Code:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

You will see a ton of "red" error messages. This is ok. Just let it finish and then reboot.

Jim29er · Jan 23, 2025

Hello,

I'm having an RDP issue with 26100.3025, which didn't exist in 2894 and earlier. I've reproduced the problem on several different computers, and am hoping others can confirm it.

In a nutshell, I'm having problems reconnecting to disconnected RDP sessions, on computers running this release preview build. Sometimes the sessions will reconnect normally (quickly) and function normally, other times there will be a short (several seconds) pause of the remote's desktop background before the desktop will appear and function properly, and still others the session will get "stuck" on the remote's desktop background (no UI elements appear), or the UI elements will appear but can't be clicked/interacted with. Resizing the RDP window on the local, also does not resize properly on the remote.

These problems seem to occur, after the remote computer has been in a disconnected RDP state for a while (as in, overnight, but probably shorter), and the severity seems to differ based on how many programs are left running on the remote computer.

I have a couple of examples. One of these computers is running in Azure, with a static public IP exposed for RDP (source-address restricted, of course). When I'm not able to reconnect to the disconnected RDP session (with this one it's been a stuck background), I restart the instance through the Azure portal, and then am able to RDP in normally. Also, if I log-out of the computer (vs. leaving an RDP session disconnected), connecting again later via RDP has worked fine.

The other example, is a VM running in an enterprise vSphere environment. That one is internal to the corp network, meaning I need to connect to the company's VPN first, before establishing an RDP session. When I'm not able to reconnect to the disconnected RDP session, I can log in to the computer using the console through vSphere. After doing this, connecting via RDP (which then overtakes the console session) will sometimes start working properly again. Other times, the desktop UI elements will be visible, but cannot be clicked/interacted with. If I then get on the computer via the vSphere console again, and log out of Windows, a new RDP session to the computer will work fine again. I normally have a bunch of programs running to make working more convenient (Outlook, several browsers/tabs, SSMS, etc.), and it seems the RDP reconnect problem happens more often when more things are running, but I haven't been witnessing the problem long enough to know/verify for sure.

So finally, is anyone else able to reproduce this behavior?

Cheers!
