The thing is, when you make one shortcut, it might lead you to make a second or a third one in the future. That way you are only making your setup less and less secure.

Some time ago, I asked why is everyone recommending using Linux distros on airgapped systems when your computer won't go online anyway? It was maybe o_e_l_e_o who explained it. There are far more attack vectors and backdoors on Windows than on Linux. Windows is a close-source OS with a wider market share than Linux. More people that can be attacked and more incentive to come up with different ways to break its defenses.

If you start making shortcuts and say I am just going to use Windows, the next thing that might happen is you deciding not to remove the WIFI or network cards to make it easier for yourself. While you at it, you might want to save yourself some time and not format your OS and install a clean version on it. After all, you are not going to connect it to the internet. One day you could decide to connect your "airgapped" computer to the internet just for a little bit because you need to check something, and it's quicker than turning on your other computer.

To avoid all that, you should respect all the recommendations or not do it at all and go for the next best thing - a hardware wallet.
