C:\Windows\system32>reagentc /enable <- Windows start copying rocovery boot files place where reagentc /info status pointing. That is not easy to expalain, but i think i hit correct point.- Thank you! Works perfect
DmBer Totally sad Microsoft hasn't fixed this update issue. The least they could do is update the Windows 10 media creation too by adjusting the partition size of the recovery drive. Then the issue will not exist when installing a fresh copy of Windows 10. Guess that would take a thought process by someone at Microsoft.
Arto_MontonenI'm that fix will break windows..
🙂
On many computers I have a -> error for this patch, but other updates install correctly and the computers work fine.
I believe that Microsoft, unfortunately for Windows10 -> will not fix this during a standard update, only upgrading to Windows11 is a hassle-free solution if your computer meets the technical requirements for Windows11.
The current version of Windows10 = 19045.3930 , so it seems that your system is outdated , can you explain that?
I'm not wasting my time on this mistake, I've already explained why. I don't recommend your steps.

My Windows 10 Pro is not outdated? The version is the same 19045.3930 and there is no error because the size of the recovery partition is 759MB.
I updated one version of Windows 10 Home PC last week and it didn't get stuck with this error. The user had forgotten the windows PIN code and claimed it was 0000, but that is no longer allowed by Microsoft. I found the e-mail address and password of his Microsoft account, which I used to change the new PIN code. His computer hadn't been used for over 6 to 12 months because logging into Windows 10 Home didn't work. The Windows PIN code can be changed if Microsoft account email address and password have been written down on a piece of paper.
