supposedly fixes an issue with windows update, but also changes system files to support upgrade to Windows 10

After removing all the updates you want removed, reboot your computer

then you will have to HIDE them to keep them from re installing themselves

run windows update, and check for updates

right click every update from this list you previously removed and select HIDE

now windows wont re-install the updates

->Removing "get windows 10" nags / preventing windows10 re-infection

Microsoft made sure this was quite difficult, and still is to do manually, however someone has finally made it easy to remove the upgrade nags and prevent the system from becoming re-infected with windows 10.

NOTE: this does not remove ALL of the telemetry spying, and instability causing updates as noted above (only the get win10 notification updates and install files)
