How do you get fake pop-ups?

Howdy! It’s been a while since I’ve visited this forum… Anyway, how do you get those fake pop-ups for tech support scam numbers to come up? I have a new gaming laptop now, (16GB RAM, Intel Core i7 9th Gen processor) and I’ve got a Windows 10 VM set up on it, so I’m just itching to do some scam bating! LOL
