Opening block to get admin access:

To be honest, I am not certain why this next thing is here (I did not write this batch) but it is harmless (it's a ping).
ping 1.1.1.1 -n 1 -w 5000 >null

Block to remove the install directories for MP:

Block (long) to clean the registry of MP entries:

Block to remove MP firewall rules:

That's all it does.
