Resizing the Recovery partition to 750 MB resolves the issue. That applies if you use the Windows-default winre.wim.

Dito.. facing this issue this morning on over 500 devices.....

Thanks. After expanding the Windows RE parition using the steps in the article you linked the update installed without an error. Windows 10 22H2 32-bit running in a Hyper-V VM with a MBR disk. BitLocker not enabled.

The resolution mentioned above at this link worked for me. After running through these steps the update works without a problem: https://support.microsoft.com/en-us/topic/kb5028997-instructions-to-manually-resize-your-partition-to-install-the-winre-update-400faa27-9343-461c-ada9-24c8229763bf

My issue is that they are doing it several times a week! I need to find something out and I have to click through next/next/next....I know when that happens the browser has also opened my home page but maybe there is something interesting going on that might be handy, I just wish they would save the darn things for Sunday or some like that. Worse though is that they are so fixated on Win 11 that 10 is getting no new features, my Gen 6 PC can't upgrade and they keep making me aware that I'll have to throw it away next year/or else.....I want to know if the TPM change in the OS has actually saved even one PC from an infection. Their constant BS with killing working programs and OS's to try and make us spend money (this month it was Clip Champ) should be illegal
