You don't even need to do that. You just need to create a second Windows account, dump all your porn shit in C:\Users\$porn-account\Documents, and hide C:\Users\$porn-account\ so you can't see the folder on your normal account. It's virtually impossible to get exposed on stream unless you actively type the directory path of the porn. Even having $porn-account as an option for what profile to log in as isn't that big of a deal since the streaming software is behind your streaming account. The only real way to get exposed would be if you first log in to the porn account and sign in to your streaming account without signing out of your porn account first. If you hover your cursor where you would log out/shutdown/restart the PC, people would know that you're logged in to another account. But even then it only exposes you as someone who enjoys porn and that's only if you make it really obvious your porn account is a porn account (ie a Windows account called Porn). If you use an entirely innocuous name like your real name, most people would just think that Windows account is for your personal life.

I really don't understand how people are still being busted with porn on stream in 2024.
