Kill Windows Update processes and services
# kill-updates-precise.ps1
#
# So what is going on here? While developing my kernel driver for Windows
# I have found the fastest way is to have the target VM set up, and
# be ready for drvier to be deployed in a snapshot, deploy driver, test,
# then rollback VM.
#
# Sadly, when Windows is restored at each rollback, it kicks of a series of
# update checks, like Windows Updater, Edge, OneDriver, Google etc.
# It is not enough to disable Windows Update, or Group Policy.
