I have installed this update on 2 Windows 11 25H2 computers but it will not install on 1. I have read there is a problem with some computers and have tried the fixes I found but to no avail. Has anybody had this problem and overcome it?

Yes, I too had problems with this update on just 1 of 4 PCs. Also, on
that PC, the Start menu had blank icons again, a problem which I
posted about previously, and, when restored, so too did the last
backup image, to my great surprise. So I went back one image
further, and its icons were intact, but the update still wouldn't
install, so I re-imaged again, and did a re-install from the relevant settings menu. Nearly all my settings and Explorer views survived,
but I had to clear all the special folders clutter out of Explorer
again.

1 out of 3 computers for me. Nothing seems to be broke. I do have a backup image made before I tried installing this from a cumulative update. I think I will wait and see if Microsoft fixes it because they are aware there is a problem. Thanks for the response.

On a few of my desktops I have a C: partition with 300 GB of free
space, but with something immovable at the end, so maximum shrink
space just above 40 MB. Since it is an SSD, the system does not allow me
to do a defrag run to try to allow more shrink. The recovery partition
is about 2 GB immediately following the C: partition, and it has about
200 MB free. If I *could* shrink the C: drive, I could make space, but
disk management will not allow me to extend the recovery partition to
the "left".
This seems like it must be a common problem on systems with a 500 GB SSD system disk that are upgrading from Win11 24H2 to 25H2 and need to
achieve 400 GB of free space on the recovery partition. Is there a
cookbook for how to do this?
- can it be done with the standard tools in Win11 Pro?
- can I do it with AOMEI Partiton Assistant?
- is there a tool to explore the recovery partition? It is an NTFS file
-a system, so it seems it should be possible to mount it as drive R: and
-a point File Explorer at it to clean it up
Paul and Winston, can you guide us?
Maybe it is as simple as setting a magical registry key that says
"WinRE, please expand recovery partition to 400 GB free space" and then restarting ;-)

200 MB free on the Recovery is a concern.
Did you perform the recommended Powershell command suggestion for
free space on the disk.
GET-VOLUME
If so, posting information on that results would be a starting point.
Run the command, copy and paste the results in a reply.
Additionally, for the recovery partition it would be helpful to know
your disk # and recovery partition #
Powershell admin command. Copy the below command, paste or type into Powershell, run the command, then copy and paste the results in the

I hope Google translates well from Italian to English, but I'll give
you a tip that you might be able to solve much faster.
First, AOMEI Partition Assist can shrink and manipulate partitions. I
used it on one of my PCs to solve the same problem.
But honestly, on my main PC, I did everything differently.
Get Macrium Reflect X, make a system image of everything on the SSD
elsewhere (external drive), and run Macrium recovery on a USB stick.
Delete all partitions using the Windows 11 ISO, if you can.
Launch Macrium from the USB stick, tell it you want to restore a
single partition at a time. You'll select it from top to bottom, but
also tell it to expand it so it's larger.
SOLVED.
And you also have an excellent program to install to make backup
copies of Win11 for safety, now it is also obvious I think, but it is
truly excellent, it has saved me many times and allows this creative
use of backup & restore by changing the size of the individual
partitions, keeping all the GUIDs and the information present intact.

Looks like the Recovery partition is on the right(and where it should be)... ...and sometime in the past(b/c I suspect the original oobe Recovery partition was 1 GB) and one or more times Windows Update(when the recovery had 250 or more free space) shrunk C and enlarged the recovery to its current 1.17 GB.
Based on the information Lars provided, it does not necessarily indicate that the Recovery partition was moved from any other location, nor being re-sized by 3rd party application.

I am still stuck without a simple way to create the needed 400 MB of
free space in the recovery partition. As I understand it, the path Paul
has suggested is to create a bootable USB stick with a 3rd-party partitioning tool, and use that to move the partition boundary.
That sounds a bit cumbersome and scary. And based on recent threads
here, this is becoming a problem waiting to happen for many Windows-11 users. Every Windows-11 machine I have looked at recently has less than
250 MB of free space in their recovery partition.

When I tested, there was no structure at all at 50%, so I failed
to reproduce the situation. I know there are definitely blockers
at 50%, because I've had them before and the Shrink Volume would
not go below 50%. When I tried the AOMEI, it had no problem shrinking
C: a lot more than I needed (and it could do that "online" as
there were no blockers). I could also move the Recovery Partition
to the left then, followed by resizing it as desired. The only problem
with AOMEI, is having a numeric display for precise movement of
the sizes I want. In some cases, the GUI is a tiny bit lacking.
Some dialogs have dimensions, and some are just graphical.

I tried a bunch more archived VHDs I have on the NAS, and none of them have blockers
either. (I use JKDefrag just for the "block view" so I can see where items are
located on disk. I am not making any changes at all with JKDefrag. I use it for surveillance.) CoPilot suggested a list of items that can function as blockers, so I'm going to try that next (after I come back).

and running from a WinPE, while it does the resize in that case.
I am still stuck without a simple way to create the needed 400 MB of
free space in the recovery partition.

That sounds a bit cumbersome and scary. And based on recent threads here, this is becoming a problem waiting to happen for many Windows-11 users. Every Windows-11 machine I have looked at recently has less than 250 MB of free space in their recovery partition.
When I tested, there was no structure at all at 50%, so I failed
to reproduce the situation. I know there are definitely blockers
at 50%, because I've had them before and the Shrink Volume would
not go below 50%. When I tried the AOMEI, it had no problem shrinking
C: a lot more than I needed (and it could do that "online" as
there were no blockers). I could also move the Recovery Partition
to the left then, followed by resizing it as desired. The only problem
with AOMEI, is having a numeric display for precise movement of
the sizes I want. In some cases, the GUI is a tiny bit lacking.
Some dialogs have dimensions, and some are just graphical.

An update on using Partition Managers.
1) A second attempt to use AOMEI, resulted in a refusal of it
to do a Move/Resize. A "free" product with a nervous disposition.
2) Paragon Partition Manager 14 Free, continues to function (for as long
as I've had it, it will do a Move/Resize). It reboots, and it took
half an hour to shrink a 500GB partition to 250GB (when the files are
in the lower 80GB of the partition). It puts text on the screen after
a reboot, and the text, I didn't know where (what subsystem) prefers
it that way.
3) I installed Minitool Partition Wizard 13.6 or so.

It would download some AV where the name begins with an "A" if given
a chance, which is why the testing was done with the Ethernet cable unplugged.
The test disk had two Windows partitions. While booted into Partition 2,
I had it shrink Partition 4 and it did that while Windows 10 continued to run.
It moved the MFTMIRR out of the way (put it much lower on the partition).
The interesting case, was when I was booted on Partition 2 and I asked it to
shrink Partition 2. It wants to reboot. The same kind of text Paragon puts up,
the Minitool tried to put up. In particular, it tried to "lock some memory" on
my 4930K and this was failing to work. The text mentioned
/filesystem/ntfsresize , so it is using a Linux utility (likely the same one
that Linux GParted uses). That means the reboot environment it is using, is
some pared-down Linux setup.
This means, for Lars, the Minitool stands a chance of failing during the
reboot session, after which it returns to Windows again.
That means, so far, Paragon Partition Manager 14 (PM14) appears to be the winner on this round. But if Paragon is also using ntfsresize, you might
as well just boot a Linux LiveDVD/ISO (via Rufus.ie if necessary) and just
do it there with GParted, which would also use ntfsresize and friends.

Have you considered just deleting the recovery partition, expand the C: drive and living without?-a Prepare a bootable USB in case of needing to perform maintenance on your Windows install ...
I need to confess that I gave up on getting Windows-11 to work at this time, because my most urgent priority was to get Fedora Linux F43 running again, so I reinstalled Fedora in "take the whole machine" mode.
I suspect that it was a cascading series of problems, beginning (conjecture) that during the almost 4 months I had not booted into Windows, the laptop finally became eligible for the 25H2 upgrade, and that installing the feature upgrade also tried to upgrade the recovery partition, which failed because it ran out of space. And (still conjecture) it also tried to fix the secure boot key in the EFI partition, and breaking that too, because that (small EFI partition served double duty as Linux /boot/efi. Because Linux was installed after Windows, it had been set to boot into Grub, from where I was booting Windows by selecting "Windows Boot Manager" from the Grub boot menu.
And the Windows update script was not set up to handle this kind of system.
So for now, the little ASUS laptop, purchased for $150 at an after-Christmas sale in 2022, is a pure Linux machine. Bringing it up after this re-install has its own issues, but they do not belong in this newsgroup.
Thank you for the detailed responses. I have learned a lot about how the system administration issues in Windows and Linux are both similar, but also different.
