Syspreping a Hyper-V machine

If you want to sysprep a Hyper-V machine, make sure it has no snapshots.

I was syspreping one of my Hyper-V machines, I copied the syspreped vhd and created a new virtual machine linked to this existing syspreped vhd. When I start this new virtual machine it starts as it wasn’t syspreped with menu to select either to “Safe mode” or to “Start Windows normally”.

I deleted the snapshots that I don’t need and I applied others to the original virtual machine. After this, I was able to sysprep and create a new virtual machine successfully.

PS: Usually we will sysprep a clean machine, not a machine with applications and services installed on it with so many snapshots.
