When doing a scratch install of Windows Server 2022, some brainiac at Microsoft thought it was a good idea to place the recovery partition at the end of the Disk 0 Volume. So, when you need to extend your "C" drive, you end up with the recovery partition blocking the way. Here are the steps to resolve this issue (and I'm assuming you've already added space to the virtual disk).
Step1: Remove Existing Recovery Partition
Run CMD as Administrator and execute the following command: reagentc /disable
C:\>reagentc /disable
Next, run DiskPart and execute the following commands:
diskpart
list disk
select disk 0 (or whatever happens to be the disk ID with the recovery partition)
list partition
select partition 4 (again, select the appropriate partition listed as the Recovery Partition)
list partition (ensure the recovery partition has a * beside it)
delete partition override (this deletes the recovery partition)
list partition (the recovery partition should now be deleted)

delete partition override (this deletes the recovery partition)
list partition (the recovery partition should now be deleted)
Step #2: Go into Computer Management and navigate to Disk Management
Right click on the "C" partition and select "extend" and click Next
Reduce the size of the extension by 1GB (see image below as example) to reserve space for the new recovery partition.
Finish task. Now, the "C" partition should be larger and there should be at least 1GB left at the end.
Right click on the "C" partition and select "extend" and click Next
Reduce the size of the extension by 1GB (see image below as example) to reserve space for the new recovery partition.
Finish task. Now, the "C" partition should be larger and there should be at least 1GB left at the end.
Step #3: Create a New Recovery Volume
Right-click on unallocated space
Choose Simple Volume
NTFS
No Drive Letter
Leave Partition Name Blank
Finish task.
Step #5: Return to CMD as Administrator and DiskPart
Run the following commands:
List Disk
Select Disk 0 (or other as appropriate)
List Partition
Select Partition 4 (this should be the new partition you just created in disk manager)
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes=0x8000000000000001
Right-click on unallocated space
Choose Simple Volume
NTFS
No Drive Letter
Leave Partition Name Blank
Finish task.
Step #5: Return to CMD as Administrator and DiskPart
Run the following commands:
List Disk
Select Disk 0 (or other as appropriate)
List Partition
Select Partition 4 (this should be the new partition you just created in disk manager)
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes=0x8000000000000001
Step #6: Exit DiskPart and Return to Administrative Command Prompt; Re-Enable Recovery Partition
C:\>reagentc /enable
Return to Computer Management->Disk Management
Partition should now show as Healthy (Recovery Partition)
C:\>reagentc /enable
Return to Computer Management->Disk Management
Partition should now show as Healthy (Recovery Partition)
