I tried a clean install with 27928.1 ISO created from uupdump, the installation completes fine.
But then I see the same issues that I saw with the in-place updates done with the same ISOs.
Cannot update many Apps from the MS Store and some other ones that update cannot open.

We'll see what happens with the next build ISO, this is definitely broken.

The problem is the UUPDump people didn't really acknowledge the issue or even try to help fix the issue from the brief few messages in that thread, I haven't read the newer responses yet.

Not familiar with Deskmodder but how did Deskmodder actually build the ISO because maybe it also used uupdump or something similar to uupdump's method which is why the same problem still exists. Also, been wanting to ask you a question about the built-in Windows Update Repair install. When you used it, did it do everything inside Windows Update as I tried it on Beta and it downloaded, installed and completed all in Windows Update. Unlike a Windows update to a new build or using the UUPDump ISO to do a in-place repair install, it does not require a reboot and does not update anything when one reboots. Reason I am asking is my notebook motherboard did have issues where the machine will reboot randomly within seconds to minutes and sometimes a few hours from the spinning part at the POST screen, it turned out one of the capacitors eventually burn down and the machine no longer powered on and sometime during May 2025, when I did the Windows Update Repair install, it corrupted the WinRE file so it was no longer working and yesterday I did do a Windows Update based repair install and while it did the download, install and complete while in Windows Update after I already updated to 26120.5761, it did not require rebooting and rebooting didn't seem to have the updating files process like I see with the normal UUPDump ISO in-place repair upgrade install or when Windows Updating to a new build and the WinRE file is still corrupted so it never touched the WinRE like a in-place repair install would.

The 27934 ISO built from uupdump has the same problems. I just tried today 8/29/2025.
No problem with Windows Update.

I bet DESKMODDER also uses uupdump.

I just read the rest of the messages on mydigitallife and it's like they can't reproduce the probkem. I wasn't asking if you were having problems with Windows Update. I was asking you if the repair install using the Windows Update method actually updated files when the system boots like the in-place repair install when using the ISO from UUPDump or not since you are the only person I know who has used the built-in repair method.

My problem was not created by Windows Update or software but because the capacitor was failing, it was causing very frequent random reboots like someone hit the reset button which was probably why I got the corrupted WinRE as that was the only thing broken which this DISM Check, Restore, Scan health does not scan as those came out clean.

They cannot reproduce because they did not try to update the Apps from the MS Store.

That's what I think too. I mean it seems like the MDL people are building ISOs and don't have the issue.

That's probably why they never responded to your last post about the apps having higher version numbers to begin with where the problem is.

They don't have the issue because they are not trying to update the Apps from the MS Store.
That reproduces the problems.

I will have to wait for the next official insider ISO from MS. The official 27924 does not have these issues.

I wonder where they are getting the apps to build the ISO from. Does the official MSFT ISO include the same version of the apps or different ones?

I think the official MS ISO 27924 has also Apps that need to be updated, and the updates from the MS Store work fine after a clean install.
I will have to check the exact version of the Apps, next time I try with the MS ISO.
I hope they push out a new one soon. The reason I use the ISO to update is because I have several machines and I don't want to use all my download allowance from AT&T. I will have to pay extra if I go over the limit.

This really sucks.
Anyway, the Windows Update install on Canary is a full install similar to the one done from the ISO. The Build number changes every time to a higher Build.
IE: From 27928.1 to 27934.1.

Yeah, the capped sucks. I was able to get unlimited bandwidth when they offered their gateway for 2 years without paying the $25/month fee which includes unlimited bandwidth.

I did a Windows Update yesterday from Beta 26120.4520 to 26120.5761 and then tried to do a Repair using Windows Update which is also for 26120.5761 and it seems all it did was download, install and then it was completed. There was no restart required like I remembered last time and rebooting went straight to the login screen from the spinning circle, it didn't do the reboot several times with the first one starting at 30% installing updates like it does when Winodws Updating builds or when using the UUPDump ISO to do the in-place repair upgrade so maybe if it's the same build, all it does is replace files in Windows Update. I'm probably going to do a UUPDump ISO but will probably need to read all the threads from 26120.4441 and each build after to get all the id's for vivetool.

Try the uupdump Canary ISO 27934 so you can reproduce the problems and add your comments on MDL.

I would but I run Canary under Hyper-V as a VM on Beta.

For one of your previous questions.
I just tried a clean install of 27924 with the official MS ISO.
The versions of the Apps after a clean install are the same low level as on the uupdump ISO, but the difference is that they update to the latest level from the MS Store without any problems.
When doing a clean install with the uupdump ISO many Apps fail to update on every retry.

Hard to say what is causing the Apps update problems when using the uupdump ISOs.

Something is definitely not compatible in the Apps update process when using the uupdump ISO.
I hope they figure out the difference and fix the problems.

That's interesting. I thought you said only a in-place repair/upgrade install with the UUPDump ISO had problems but if a clean install does too then it's definitely some other problem. The issue is getting them to look into it and test upgrading the apps from a clean install since there will be no resolving the issue if they keep ignoring it.

I actually said before that the apps failed to update after a clean install of 27934 with uupdump ISO.

F.Y.I.
uupdump ISO 27950.1 finally fixed the problems reported with last 3 uupdump Canary builds.

That, in spite of the guys on digital life that were trying to deny that there was a problem.

No more errors updating or opening the Apps from MS Store.
