When Microsoft announced that they would give Windows 10 as a free upgrade to all Windows users, it seemed like good news. Then they decided to force it on everyone by using Windows Update to push KB3035583 to everyone as an 'important' update. This installs a package called GWX (get Windows 10) that does some obvious things:-
* Displays a white Windows logo and many flags in the notification area.
* Brings up a dialog offering you Windows 10 every time you boot your PC.
* Background downloads the actual Windows 10 installation files to your C drive.
* Prompts you to run the install, reportedly with a dialog box that can't be closed.
GWX also engages in some borderline malware behaviour:-
- GWX is installed under an account that prevents even users with Administrator privs deleting it.
