How could I prevent Win 10 from accessing the net ? I know I can disable adapters. I want another solution. Background : I have a tiny Win10 ( 1.2GB ) booting from a vhd. I use it for maintainance. I use it on more than 1 system (it's 'universal') so disabling adapters is (edited to not) not a good solution. Can I disable some service, delete some files, use gpedit .... etc that will never allow Win 10 from accessing the net? Right from the time it boots up. I don't mind a solution that's irreversible.
