system disk

Hello everyone, I really need help, how to resize the system disc on Windows Server 2022. I tried diskpart, GParted software... but nothing helped. It's not possible since Win2022 came out. Does anyone else has any other idea?

I have read to many OMV users that, like me, one day their sda system disk began to run out of space and despite increasing the space in proxmox, that space is not reflected in OMV So I made this guide of what has always worked for me hoping that someone will help and at the same time can help...
