    I’m getting that stupid 0x80070643 error again like I got months ago. Back then I increased my recovery partition to 1GB then it installed fine. Now with KB5046400 I am getting the same 0x80070643. I checked and my recovery partition is still properly set to the 1GB partition I created months ago on my C:\ 980 Pro. My WinRE is at 10.0.19041.3920 per HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion. Any ideas on what to do? Thanks.

    Welp, looks like the KB5046400 update is throwing up the famous 0x80070643 errors again which we all can remember from KB5034441.

    This Windows 10 22H2 installation wasn’t modified yet as it was kind of recently installed last year in November, it were usually older installations having trouble with this update before.

    It is installed on a 990 Pro 4TB where the OS automatically assigned it 531mb for the recovery environment, a previous install assigned only 510mb and I believe it used to be 500mb default in the past.

    Just great to see that this problem just keeps coming back.

      dealing with updates sounds so sad. If you can remember KB names, you’ve gone too far.

      Why do you put yourself through it??
