Re: The obligatory question
Bless him, still going after these years and providing useful stuff.
Tried it, used it. It works by creating/setting two keys in your registry.
All credit to Mr Gibson, the following is paraphrased from his site.
Under this key, the 32-bit DWORD value “DisableGwx” is set to 1.
When DisableGwx is set to 1, the upgrade offer icon is suppressed.
Under this key, the 32-bit DWORD value “DisableOSUpgrade” is set to 1.
When DisableOSUpgrade is set to 1, any previously downloaded Windows 10 files are deleted and Windows will never attempt to upgrade the current operating system.
