this script is really simple and could not work properly, burn your cat
and cut your Little Pony head.
#How?
This script kill GWX executable, then remove some Scheduled Task about
GWX program, uninstall some KB with wusa.exe and hide it to prevent automatic
reinstallation.
#TODO
* Add privilege elevation error when the script is not launched with Administrator's rights
* Add the possibility to use arguments when calling the script (then ps script could be call from
another script)
* Add privilege elevation error when the script is not launched with
Administrator's rights
* Add the possibility to use arguments when calling the script (then ps script
could be call from another script)
* Remove GWX Files before uninstalling KB (check remove_gwx_file branch)
* ~~Update the windows update list to hide kb that aren't yet listed~~
* ~~Speed up hide_update~~
* **Tell me**
