Change start mode for Windows services via PowerShell

Some Windows services are unnecessary for some users or some production environments such as Windows Update, if you have WSUS!

Disabling or stopping services on one or two computers is very easy but for 100 computers or more!

I wrote a script for that, you can change services start mode on one or a list of computers by this script.
