KB5034441 Security Update for Windows 10 (21H2 and 22H2) - Jan. 9 Win Update

johnpd said:

We have three Windows 10 computers in our little community computer lab. Two are identical HP minis and the other is a Lenovo laptop. The two HPs have 980mb Recovery partitions. The Lenovo has a 1000mb partition. How big do we have to make these things? Here is the layout:

HP Minis
----------------------------------------------------------------------------------------
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 System 360 MB 1024 KB <EFI Partition>
Partition 2 Reserved 128 MB 361 MB <Reserved area>
Partition 3 Primary 222 GB 489 MB <OS (C:) Partition>
Partition 4 Recovery 980 MB 222 GB <Recovery Partition>
Partition 5 Primary 14 GB 223 GB <HP Recovery Image>
-----------------------------------------------------------------------------------------

Lenovo Laptop
-----------------------------------------------------------------------------------------
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 System 260 MB 1024 KB <EFI Partition>
Partition 2 Reserved 16 MB 261 MB <Reserved>
Partition 3 Primary 212 GB 277 MB <OS (C:) Partition>
Partition 4 Primary 25 GB 212 GB <Lenovo Recovery Image>
Partition 5 Recovery 1000 MB 237 GB <Recovery Partition>
-----------------------------------------------------------------------------------------

I made all my recovery partitions exactly 1000 MB, and I've had no trouble.
Any size around about that should work. I'd be surprised if the 980 MB recovery partition doesn't already work for you.

You must check on your 3 computers that the recovery partitions are active. In a Command Prompt window as admin type: reagentc /info

You should see enabled which is good or disabled which is bad your partition is broken

"If the WinRE is installed, there should be a “Windows RE location” with a path to the WinRE directory. An example is, “Windows RE location: [file://%3f/GLOBALROOT/device/harddisk0/partition4/Recovery /WindowsRE]\\?\GLOBALROOT\device\harddisk0\partition4\Recovery\WindowsRE.” Here, the number after “harddisk” and “partition” is the index of the disk and partition WinRE is on."

The HP Minis are ok. When the first has been updated successfully, you can check in PowerShell by
the command: Get-Hotfix
In the registry
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]
you should find: "WinREVersion"="10.0.19041.3920"
it's the last entry on the right side.
If this is ok, you can replace/exchange the WinRE.wim in all other machines by this one.

The problem is the Lenovo. There it is in Partition 5. Here the above mentioned exchange would help.

Type reagentc /disable and the WinRE.wim will be moved to C:\Windows\System32\Recovery
By using 7z running as Administrator it can be exchanged easily. When ready, just type reagentc /enable and your problem is solved.

The "HP Recovery Image" and the "Lenovo Recovery Image" are the dangerous partitions on the machines.
If s.o. presses accidently the <F11 (?)> button your machine is ruined. If there is s.th. that you never need it is the machine as it has been delivered! You can loose everything!
Go for a Backup&Recovery solution. (Macrium, AOMEI, ....) That would be save.
After a successful backup you should delete the OEM Partitions.

This helped me.
KB5028997: Instructions to manually resize your partition to install the WinRE update
https://support.microsoft.com/en-us/...9-24c8229763bf

Thanks @spectator

My system failed to apply the update giving the 0x80070643 error. I was gonna leave it for MS to supply a fix but then I felt brave and followed the method outlined in the post above and all went well. The update went through afterwards when I hit retry.
The old RE partition was 517MB and newly created RE partition is 767MB (+250MB increase as recommended).
Unless you know your way around the system (powershell/diskpart etc.) it's definitely best to wait for the fix to be supplied.

Neither the HPs nor the Lenovo got updated. It started the install of the update and then got the 0x80070643 error. In all cases the Recovery partitions are empty. Here are the reagentc results. They point to the right partition.

@johnpd
cmd (admin)
Dism /Get-ImageInfo /ImageFile:\\?\GLOBALROOT\device\harddisk0\partition#\Recovery\WindowsRE\winre.wim /index:1

On HP replace # by 4
On Lenovo replace # by 5

I hope that you don't have modified OEM WinRe.wims
Your Recovery Partitions are not empty!

Hi, how did you determine that?

One way is to use a suitable partition manager, rt click the partiton, click Explore.

Also please check that the Advanced Startup options actually work e.g. try booting to a command prompt.

I was wondering about that. Apparently Windows Disk Management does not give the correct info for those special partitions. I will try MiniTool PWiz to see what it says. I tried it on my local computer and that does give the right stuff.

that means, that the reagentc / disable command does not work in the wrong directory
So use 7z as mentioned above
otherwise the winre.wim gets lost!
We have to reformat the partition first

Only (!) if there is a WinRE.wim in C:\Windows\System32\Recovery
run step by step
diskpart
sel disk 0
sel par 3
format quick fs=ntfs label="Recovery"
assign letter=R
exit

mkdir R:\Recovery\WindowsRE
xcopy /h C:\Windows\System32\Recovery\Winre.wim R:\Recovery\WindowsRE
xcopy /h C:\Windows\System32\boot.sdi R:\Recovery\WindowsRE

Reagentc /setreimage /path R:\Recovery\WindowsRE /target C:\Windows
reagentc /enable

Watch the system response after each input

I have worked out what goes wrong. A reboot cleared the folder with the recovery files so nothing there to copy. I did a reinstall and the same happens so have just hidden the update I have spent days on this and as it wasn't there for the tome I used this laptop I don't see the problem in not having it. Thanks for help but I kept geting things wrong problem of 80 and poor eyesight with dyslexia.

The solution could be easy. But till now I never found a good tutorial considering all aspects during a new installation. When I run a clean installation the

- ESP-Partition size = 260 MB
- MSR-Partition size = 16 MB
- C-Partition size = 150 GB
- Recovery-Partition size = 1024 MB

So I never have to change anything at all!
