Or this might happen.

Update faker
Update Faker allows you to “fake a system update”, it’s the perfect way to prank your friends, family members or colleagues. Especially when they’re working on something rather important.

Yes, it’s just a silly prank (reminds me a little of Hacker Typer), but you could see it as an important security/GDPR lesson.

Ever since the launch of updatefaker.com we’ve been flooded with positive feedback both online and in real life. And everyone who’s ever fallen victim to update faker will never leave their PC unattended again, which certainly is a good thing. You never know what bad things people are up to. This website is literally one of the least bad things that can happen to an unattended PC.
