Hi, I'm here for help because they haven't been able to update Windows 11 to the latest version for over a year.
I've tried everything, but I'm full of hope that there's something that might help.
I'm stuck on Windows 11 Pro 21H2 (compilation 22000.434)
The system works fine, but I know that if I don't update it, my applications will stop working at some point.
I can't and don't want to do a clean install because I started playing around with streaming and I have a lot of applications and configurations related to audio and video that I wouldn't want to start from scratch because it took me a lot of hours to perfect it the way I wanted.
I tried a clean boot, removing the antivirus, disabling all USB devices, installing from ISO but also from a pendrive. Every time the installation gets to 100% and I have an error that the update could not be installed.
After restarting the computer, I still get the error:
0x80004005 - 0x1000A. The installation failed in the DOWNLEVEL phase with an error during PREPARE_FIRST_BOOT operation
Sorry for my English, but I'm using a translator.
I'm a person who can handle computers very well, but unfortunately I failed at this.
I have a lot of disks, disk I and disk D are external USB. I disconnect them for the update.
I have the system on disk C, but it's a larger disk divided into two partitions C and H and there's also the EFI system partition there.

The computer itself works fine but I often get an error: Host Process for Windows Services Has Stopped Working
I noticed that nothing bad happens when this error pops up, but it probably suggests that something is wrong with the system files. The error started appearing when there was a problem updating to a new version of Windows, so I think it's related.
Is there anything I can attach? Any logs that might help point someone to a solution?
Thanks in advance if anyone is willing to help me with this.
