There are a couple of great articles which thoroughly explore how to remove the Windows Genuine Advantage Notification popups that appear, including this one.
However, i couldn’t find anything to help you remove the wgasetup file, the Windows Genuine Advantage Notification Installer when it has been downloaded but not installed.
To do so, follow these steps:
- Reboot in safe mode (press F8 repeatedly on restart)
- Search for wga* to find all files with wga in the filename. Remove wgasetup.exe file – probably located in C:\Windows\Prefetch
- Restart and enjoy.
Please note this post is not intended to help people copy Microsoft software and this website does not support such behaviour. 😉
