I found one way to solve the problem so I could install the update!
I deleted the FONT folder in the recovery partition 'Y' as this folder is more or less not needed.
This did free up enough space for me to install and complete the update.
Right now, I am thinking of how to increase the size of the EFI recovery partition but 50% (100 MG to 150 MB) without affecting its content.
Any comment or advice?
PS: Thank you for your effort to help 🙂

I have the same problem. On my dell pc when I download the Windows 24h2 update I receive an error updating the reserved system partition with the code 0xc1900201. I tried Microsoft's solution for this problem by deleting the font files in the system partition but the remaining space was not enough to perform the update. I therefore deleted certain language files from this partition just after I no longer received the proposal for this update in Windows update. Very recently I performed a recovery and after installing this update I received. I realize that there are only 2 MB free on the system partition while at least 15 MB is needed for the update. I can't increase the size of the reserved system partition.
How should I free up space in the system partition?
Can I delete its contents and use DSIM to restore the contents of this partition?
