Windows Server 2022 is new and has to be the best Windows Server there is right? Not at all. Microsoft has added a recovery partition (like in Windows Client versions) that prohibits you from expanding the boot disk like you usually would in older Windows Server versions.

Anyway, here are a few diskpart commands that will help you delete the recovery partition and allow you to expand the boot disk:

diskpart

list disk

select disk 0

Make sure partition 4 is the 523MB Recovery partition

select partition 4

delete partition override

If UAC is enabled and Admin Approval Mode is enabled for the built-in Administrator for example, you might have problems accessing network drives from an elevated command prompt. This behavior is expected, since in Admin Approval Mode all apps run as a standard user by default. If a program is elevated, it runs under a different session than the non-elevated user.

Microsoft suggests following fixes or workarounds:

1. Remap network drives via bat file or manually
2. Create this registry key, which creates a link between both sessions:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System DWORD EnableLinkedConnections 1
