I googled the actual KB and found this link: https://support.microsoft.com/en-gb/topic/kb5034441-windows-recovery-environment-update-for-windows-10-version-21h2-and-22h2-january-9-2024-62c04204-aaa5-4fee-a02a-2fdea17075a8. It seems that it updates the Windows Recovery (WinRE) environment, and the tip about resizing the partition for that is valid. You can find the link to the instructions in the KB article I linked.

I did that and the installation passed.

    I'm having this exact same error 0x80070643 issue. my pc is 2022-2023 years old. Brand new MSI Pc With Intel -i9-11980HK / Nvidia 3080 TI

    so pc age doesn't matter for anyone thinking its their pc being at old age. this error started today for me 1/10/2024 and its really frustrating and annoying to see the red error message. Always some problem with Microsoft. another big issue for years, is plugging my phone / USB device into the port of my pc. it crashes my whole Windows explorer or my desktop apps and icons would just become un responsive and freeze

    agreed.

    and besides - if we learn how to resize partitions etc to make space - well it will just be too tempting to simply install linux or something... lol
