Is there a workaround for KB5034441 install failure that doesn't require partition modification?

Thank you for the information and all the hard work. Unlike similar instructions, these are clear enough that I might give them a try, though it is a little scary messing with things at this level.

One question, will upgrading from Windows 10 to Windows 11 resolve this issue?

If not, I'll have to think about it. My understanding of the security vulnerability is that someone must first "physically" take control of your PC. I might be able to live with that. Then I have to figure out how to stop further KB5034441 attempted updates.

Wow, talking about the lessor of three evils.

PS: Hey Microsoft, why did KB5034441 cross the road? To get to the other side!

There is an easier fix, listed in the thread above, of just enabling control of the TPM for the OS. But that doesn't appear to work with everybody. I disagree with a world class action lawsuit. Have you tried to sue one of the big ones? Been there done that and am waiting for a ruling on a case against FB.

What Microsoft has done with this is paint themselves into a corner. As an example, though I have several computers, only one has Windows 10 Pro, and that is an older i3 based laptop. I'm also one of the OG's, having cut my teeth on DOS and Windows 3.1. I've learned the hard lessons over the years to not keep all my eggs in the Microsoft basket.

The day Windows 10 ceases to update, is the day that Laptop becomes an Ubuntu Pro machine. Microsoft has already told me, via the update app, that the machine is not compatible with Windows 11. What does Microsoft think, that I'm going to throw away a perfectly functioning laptop and buy another one just to install the latest Windows? One that I recently swapped the HDD with an SSD to speed up. I have to laugh at that mentality. There are at least 10 Linux OS flavors that I can think of off the top of my head that will fit that laptop like a fine Gucci glove, LOL.

Wow that is a lot of work... Microsoft Technical Support gave me an official definitive answer. A 1 step solution:

Step 1) Reinstall windows 10 with the latest version, the script with the fix is embedded in the update.

Microsoft will not post the script for the end user to download, and Microsoft will not update the update to include the script.

Of course this takes considerable preparation time i.e. full backup and hours to download, install, setup and reinstall apps and data. Seems to me like cause for a world wide class action.

Yep, I found this on the Microsoft support website and now the file works.

Since microsoft officially stated they wont be fixing this and noticing multiple websites had different instructions or incomplete commands i put this together. Tested on GPT systems not tested on MBR yet. Please verify DISK# and Partition#, my examples are common setup but yours may be different. Tried to note in steps "whichever number is listed" means yours may be different then what is in example command.

1. Check WinRE status,  enter   reagentc /info
   1. Note Windows RE Location,  specifically the PARTITION#
2. Disable WinRE, enter   reagentc /disable
3. Run diskpart,  enter   diskpart
4. Enter   list disk
5. Select OS disk, most likely the only one or the largest one, enter select disk 0 or whichever number is listed for OS Disk
6. Enter    list part
7. Select primary partition #, normally the largest size also,  enter  select part 3 or whichever number is listed on your list part
8. Enter    shrink desired=500 minimum=500 (did 500 instead of the MS recommended 250, incase future issues)
9. Enter    list part again note recovery partition #
10. Enter   select part 4   or whichever number is listed as recovery partition
11. Enter   delete partition override
12. Enter    create partition primary
13. Enter    format quick fs=ntfs label=”Windows RE tools”
14. Enter   detail part
    1. Verify *"Type: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7"*This will be GPT option in next step
    2. If anything else is listed it will be MBR option in next step
15. If GPT option from above step:
    1. Enter    set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"
    2. Enter    gpt attributes=0x8000000000000001
16. If MBR option from step 15:
    1. Enter     set id=”27”
17. Enter    exit
18. Re-enable WinRE,   enter   reagentc /enable
19. Enter  run reagentc /info
    1. Verify status is ENABLED
    2. Verify WINDOWS RE LOCATION shows partition4 or whichever was listed from step 10
20. Restart and run windows updates again
