My state is one that has recently adopted age verification requirements. Adult sites seem to be complying through IP geolocation, requiring users in my state to establish accounts. I think they are requiring a credit/debit card on file as evidence of age, but I cannot say that with any certainty.
VPN servers in less-oppressive jurisdictions bypass the account-creation requirement.








The usual options are live-usbkeys, dual-boot, and VM. All have their pros and cons. I’m not fond of any of them. Live keys are slow, windows updates occasionally break dual-boot. VM on a windows host is… blegh.
I’d suggest pulling your existing drive and shoving it in a drawer. It stays safe, ready for you to swap back at any time you want. Now you’re free to experiment all you want.
If you’re already comfortable with Windows, you can install that in a VM on your Linux host. That’s your crutch to fall back on until you’re comfortable with Linux. That would be my first significant Linux project if I were starting today instead of 20 years ago.
