Hyper-V VDI How to update, sysprep and rollout changes from Master image

How to update, sysprep and rollout changes from Master image

Right-click on the Master Image vdi, choose “revert”

Once reverted and the vdi is running, delete the existing snapshot

Apply program changes/OS updates

Snapshot

Then sysprep (C:\Windows\System32\Sysprep\) with the following settings: OOBE, generalise, shutdown

In Server Manager on the VDI server navigate to Remote Desktop Services -> Collections -> IFG Pooled Computer. Select Tasks in the top right and click Recreate All Virtual Desktops

Afterwards, revert Master Image to snapshot

Should the sysprep fail with an error message, try

Setting HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status\SysprepStatus to 7

Setting HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform\SkipRearm to 1

Renaming (or deleting) C:\Windows\System32\sysprep\Panther

Make sure to do all three each time you attempt a sysprep.
