Microsoft has released a fix. It is a Powershell script that supposedly will resolve the problem. https://support.microsoft.com/en-us/topic/kb5034957-updating-the-winre-partition-on-deployed-devices-to-address-security-vulnerabilities-in-cve-2024-20666-0190331b-1ca3-42d8-8a55-7fc406910c10 But it requires downloading a supplemental file from the Windows Update Catalog. You need to match that file to the specific version of Windows 10 that you have. Whether this script will work is unknown. I have only seen a couple of people who tried it. One said it worked, the other said it did not work. Good luck, JohnD

Same for me... Followed the above steps except for in-place upgrade (since my PC does not have hardware to run windows 11). Problem persists.

This is my own personal report. If it helps, or inspires other ideas, then great. If not, then sorry, move on to something else. Apparently the old 451 MB recovery partition is not quite enough to update WinRE. Instead of running through the nonsense of using the convoluted command-line to resize the recovery partition, I used a 3rd Party Partition Manager application "EaseUS Easy Partition Manager 16.5". I'm sure other applications will do quite nicely, but this was my choice. It has a pleasant GUI, and it fixes the issue fast. My resizing procedure involved shrinking a data partition that was consecutive to the recovery partition. Using the newly unallocated space I took from my data partition, I expanded the recovery partition to 1 GB. This can all be done in just a few clicks of a mouse, or a few taps of a screen, then a reboot. This makes it quite roomy for WinRE and I'm sure the recovery partition loves it's new home. The Update installed successfully after resizing the recovery partition. The End. You're Welcome.

I have attempted the same 'corrections' they listed; none worked, and this has happened on three separate Windows 10 devices family and relatives own: I'll wait until the next security update, MSN needs to make sure their stuff will work, not force frustrations on the users.

Are you suggesting that this is the only solution!!! What happened to the one that says that it shouldn't have occurred in the first place & needs to be fixed by MS. I'm not going to waste my time making dozens of changes to machines all over the place. Just fix it properly!!!!
