Was not able to Windows Update to this build from 26120.3950 in three attempts.

1) Attempt 1 took forever to download and install for the Windows Update portion - failed install and undo changes after the reboot after 30% went to Diagnising and Automatic repairs.
2) Attempt 2 downloaded fast in windows Update but the install failed in Windows Update after it showed 10%
3) Attempt 3 downloaded in 10 minutes but installation part in Windows Update was slow and failed install and undo changes after the reboot after 30% went to Diagnising and Automatic repairs.

Maybe something is corrupt as DISM all were fine and sfc /scannow reports no problems since I had been having restarts that were within a few seconds or within a few hours while after the spinning circle on the POST screen finishes showing so it can happen there or before the login screen shows or after login.

My CMOS Battery appears to be dead which could be the cause so will need some time to find another device to use for the instructions to replace the battery as it requires taking apart almost the entire notebook since it's on the other side of the motherboard.

You are not alone. You Still show "System > For Developers" instead of "System > Advanced"

This is the updated one:

I could not find that either in any of my machines, till I searched for File Explorer.

Dev Build 26200.5600 has it.
I still cannot find it on any other builds. The same settings for File explorer show on a different page.

All Builds got this update Windows Advanced Settings, but the result is different.

I had to do that and when I arrived on the file explorer settings page I also had to click on the button on the bottom to update the feature.

Which Build are you on? My Windows Advanced Settings was updated already when I clicked on Dev Home.
Still only works for me with Build 26200.5600.

This is what I get on all the other builds:

I don't get it on this build 26120.3964 on one machine, i Just got it on a second machine with the same build.
Typical MS inconsistent behavior on updated features.

One has this feature enabled 56005157 and the other does not.
Silly confusing CFR.

New "System > Advanced" settings:

All the builds that did not get the new "System > Advanced" settings still show the one below.

Old "System > Developers" settings:

I got one machine with 26120.3964 with the update working, but it keeps showing update now regardless of how many times I click on the button.
The app Windows Advanced Settings is already at the latest level.

My CMOS Battery appears to be dead which could be the cause so will need some time to find another device to use for the instructions to replace the battery as it requires taking apart almost the entire notebook since it's on the other side of the motherboard.

Spent the past few days since the post I am posting and I managed to update to Build 26120.3964 Beta.
1) I tried the Windows Repair built into Beta Build 29120.3950 which as seen below basically did a Windows Update to Beta Build 29120.3964 Repair since apparently it will repair using the most recent build from Microsoft and not the current build on the system even if older that did the download and install 3 times which took nearly 3 hours each except when it rebooted, it just did a regular reboot without the standard updating and then reboot with the updating after booting but instead it just rebooted straight to the Windows 11 Lockscreen so gave up on that.

2) I tried the Beta Build 26120.3964 UUPDump ISO I built earlier to do a in-place repair install upgrade except the system would randomly reboot when it was at like 95-99% in the blue screen setup program on three tries a few times and finally it did do the standard update procedure but rebooted at 7% updating after booting up and then undid the changes with the following screen:

3) Tried the MSU update for KB5058496, thanks to @JGToy mentioning it in previous Beta Builds and ofcourse the system rebooted randomly before it finished the first few times and on the fourth time, it did complete and when it did reboot and then boot up, the update restarted at 7% and basically undid the changes.

4) I did some searching on Google and it mentions Microsoft has a tool called SetupDiag that is supposed to read logfiles and give a clue on why the update/install failed and this is what it shows:

5) I figured it has something to do with the Recovery partition for the Windows Recovery Environment (WinRE) or the WinRE.wim file except my WinRE works fine since I had seen it a few dozen times daily and I have even used it to get into Safe Mode but regardless, as I had two Recovery partitions known as 4 (1.2GB) and 5 (1.1GB) with 4 being active. I also used the file browser as a Trusted User from Right-Click Tools and sure enough, the WinRE.wim is almost 900megs in partition 4 with a April 30, 2025 timestamp which was when Beta Build 26120.3950 was installed but there was a temporary folder with a newly dated WinRE.wim that was 0 bytes in size. And ofcourse usually in-place repair installs are supposed to not have problems with WinRE since it will replace the WinRE files and also create a new recovery partition as needed.

6) So after some more researching on how to create and resize Windows Recovery Partitions using diskpart,
I decided to delete both Recovery partition(s) 4 and 5 so I can combine the total space of both just in case it was the Recovery Partition or the file being the problem, I did it using my own method(s) as follows:
6a) Delete partition 5 with Minitool Partition Wizard
6b) Use the reagentc /disable command to disable WinRE so it moves the WinRE.wim file from the recovery partition to C:\Windows\System32\Recovery which was successful.
6c) Use reagentc /info to make sure WinRE has been disabled.
6d) Delete partition 4 with Minitool Partition Wizard
6e) Create a new Primary NTFS partition using the 2.3GB of available space and also quick format and labeled it as "Windows RE tools" with Minitool Partition Wizard except I noticed it did not have anything to set
it as a recovery partition or even do the gpt attributes as seen in the instructions elsewhere.
6f) At this point, I had to use diskpart for the other stuff in the command prompt:
diskpart
once in diskpart:
list disk
select disk 0
list partition
select partition 4
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac override
gpt attributes=0x8000000000000001
6g) Use reagentc /enable command which enabled WinRE by moving the WinRE.wim file from C:\Windows\System32\Recovery to the recovery partition which was successful.
6h) Use reagentc /info to make sure it shows WinRE is enabled and back at the Recovery partition.
6i) The WinRE.wim in the Recovery partition is dated April 30, 2025 as originally from Beta Build 26120.3950
7) From all the different researching, they all say the WinRE.wim file can be extracted from the Windows ISO itself but I remember reading that the WinRE.wim file is not that generic and when Windows does the installing process, the WinRE.wim file has drivers specifically for that system which was the reason I kept the original WinRE.wim file.
8) Decided to try the MSU update for KB5058496 and as expected, the system randomly rebooted before it finished so another three tries and it actually did the updating and rebooted and then did the update process and made it to 16% except the circle was spinning and my laptop screen goes to sleep as expected while my mouse worked normally but the 16% was there was 3 hours so I forced power off by holding the power button down for 10 seconds and this time, it went past the 16% and finished in 5 minutes and it got me to 26120.3964 successfully but I am still having the random rebooting problems anywhere from a few seconds to hours just like before as it could be the CMOS Battery or something with the OS itself that requires a repair install which I will do in a future Beta Build both before/and after I get the CMOS battery replaced.
9) I was also hoping to uninstall the 26120.3950 update but wheņI tried in WinRE which is a quality update, it said there is nothing I can uninstall.

@Almighty1

I'm up to build 26120.4151 on 3 machines.
My Recovery partitions are 2.5GB on all 3 machines. I've never seen any update issues yet.

Almighty1 · 2025-05-21T02:53:23-0400

Updated without issues other than what's mentioned in the previous post from Beta Build 26120.3950 in a KB5058496 MSU file based update unless mentioned below:

Windows Recovery Environment (WinRE) updated to 26100.3961 from 26100.3941 which was updated as part of 26120.3941 Beta:

The following all passed without any complaints unless noted:

The operation completed successfully.

Dism /Online /Cleanup-Image /ScanHealth
No component store corruption detected.
The operation completed successfully.

Dism /Online /Cleanup-Image /RestoreHealth
The restore operation completed successfully.
The operation completed successfully.

sfc /scannow
Beginning system scan. This process will take some time.

After the cleaning, it showed 2 Reclaimable Packages when Dism /online /cleanup-image /analyzecomponentstore was ran again.

Just like Windows 11 24H2 Build 26120.3073 Beta/26120.3281 Beta, 26120.3291 Beta, 26120.3360 Beta, 26120.3576 Beta, 26120.3585 Beta, 26120.3653 Beta, 26120.3671 Beta, 26120.3863 Beta, 26120.3941 Beta, 26120.3950 Beta, 26120.3964 Beta compared to 23H2 Build 22635.4870 Beta as well as 23H2 Beta Builds in general:
1) It takes a lot longer to load all the startup items
2) CPU % usage is way higher and system is more slugglish and lagging

I'm up to build 26120.4151 on 3 machines.
My Recovery partitions are 2.5GB on all 3 machines. I've never seen any update issues yet.

Like I said, the issue might not be Windows itself but physical issues like dead CMOS battery which I discovered when I was upgrading my memory from 32GB which is what the max Dell supports to 64GB when the machine would power on as soon as I connected the main battery and ofcourse the CMOS settings were gone on two ocassions when I tried swapping the two SoDIMMs and according to Dell Service Manual, only removing the CMOS battery will clear the CMOS settings. I could not get the rebooting to happen in various WinPE even with the stress testing memory/CPU tools. People have said that with 32GB or lower, the system will not even POST with memory with Cas Latency lower than 17 and others who have 64GB using 32GB x 2 modules are usually CL18 or slower. I'm the first one to have 32GBx2 CL16 or less memory actually posting successfully. I'll need to get a second system if I want to do a real memory test as I don't have the days for the system to be offline as I need the system for things daily so hopefully it's the CMOS battery as some people have had weird things happen with booting and stability even from posts some 9 years back. So even now, the Winre.wim is still less than 900MB and I could not find the exact error that the error code points to or atleast not sure what to be looking for using the link Microsoft provided so the easiest way would be to recreate the recovery partition with the WinRE.wim file first and if that allows the upgrade, it's not the file and the recovery partition. And ofcourse usually in-place repair installs are supposed to not have problems with WinRE since it will replace the WinRE files and also create a new recovery partition as needed.

All this time, I thought WinRE was actually something you can boot into but it's nothing more than blue screen thing where one can get into Safe Mode as a option but I did read some people deleted their recovery partition who did not do the reagentc /disable first and were unable to boot so my random boot issues fany point after the spinning circle at POST could be because of the WinRE.wim file itself. Now I wonder when Windows Update does the update to WinRE, does it patch the existing file or does it actually replace the file but hard to tell. I thought perhaps maybe my 26120.3950 update might be corrupt so tried in WinRE to uninstall 26120.3950 which should be a quality update but as I used WAU Manager, it's not shown in Windows Update History so there was nothing to uninstall. So for now, I will just update to builds when they are available either via Windows Update or using the MSU file from UUPDump as the later even if there is a new build, I still have the option available to try the build before moving to the next build to see if each build makes a difference as prior to 26120.3950, while the system did reboot, it only did it a few times with the first time being March 30, 2025 and I was able to be stable from the build right before 26120.3950 on April 12, 2025 all the way to April 30, 2025 without the reboot problem even though I did manually reboot every few days but April 30, 2025 was when 26120.3950 was updated via Windows Update and that's when it was really getting unstable at any point after the spinning circle on the POST screen.
