How to remove "Download Windows 10" icon on Windows 7 System Tray ("official adware")? [duplicate]
I managed to solve it (getting rid of the system tray icon) by renaming the folder from:
C:\Windows\system32\GWX
to:
C:\Windows\system32\MicrosoftYouShadyBastards
and rebooting. Which seems to work fine, Process Hacker doesn't show anything wierd running.
