When I downloaded a virus that turned out to be a troll. It spawned some windows with 'Trololololo...' flashed blue and red and jumped random on the screen while playing troll music.
Closing one window would lead to that window beeing duplicated.

When I got into coding, one of my first projects was a recreation of this.

So my ethernet randomly stopped working on Arch.

At first I thought it had to do with a conflict between it and my tethered phone, so I tried removing all my connections. Still wasn't working.

Next I tried to test the driver itself and make sure it loaded on boot. It loaded, but was disconnected.

Next I decided "fuck it, I know I was just using the internet on Windows, but I'll check the ethernet cable is still plugged in anyway". It was, and it was returning the right MAC address, but still no connection.

So I try debugging the driver further. Everything seemed fine, except it would time out trying to establish a dhcp connection.

Finally I figured, maybe Microsoft tried to troll me and lock out the ethernet waking on boot. So I restart my computer, load into windows and check my ethernet driver, it seems fine. I go to disable the shutdown of the card on OS shutdown. Turns out this driver no longer has that capability.

Wait a minute!? Windows is also having connection issues!?

I look to my left.

Fuck my life...

My router was off... I must of kicked the powerboard under my desk..........

I went afk without locking my pc. When I came back I saw the "Upgrading to Windows 10" screen.

windows booted up into a blue screen for a second before going to the login screen.

i almost had a heart attack

Everything is beautiful in this world expect windows..!

Got a strange thing today in class, as a teacher in programming. We have a lab where the computers haven't yet their final configuration ended, so the user used by the students is the administrator of the computer. And today, a student calls me and tell "sir, the password isn't the one you gave to us" (temporary the same for each machine until we fix the configuration).
Go to student's place, password incorrect with a hint "you know the code : up, up, down, down... oh, you don't know, huh? Too old! Too bad!"
Password was - off course - "konami".

But... how a student born in 1997 can think he can troll me with the konami code?!
He wasn't even born when I played on the NES as kid!

Sometimes I'd like to teach my students how to fly by tossing them by the windows...

I trolled my friend by telling him that there's a 100 MB data transfer restriction on Windows right now because of the Ransomware that's floating around the internet.

I can't believe it worked and now he thinks he couldn't copy anime or games from me because it exceeds 100mb file size.

What's your best troll moments to people who're not computer techies?
