To this day, I don't know what it was meant for

Imagine you are disabled and only have the use of one finger.

How do you press "Ctrl-C, Ctrl-V"?

Stickykeys allows you to use your one functioning finger to press Ctrl then release it, then press C and release it, and you'll have done the equivalent of pressing both at the same time.

Turning off that shit is one of the first things I do on a fresh install.

It allows users to press keys like Shift, Ctrl, Alt, or the Windows key one at a time, rather than holding them down while pressing another key.

And here is my obligatory; “just use linux”.

It's soooooooo easy to disable. The pop up for it even tells you how!

I like the noise it makes when you do it.

PS: That's my favorite Spongebob scene. The delivery is great.

It always annoyed me because every month or so, after getting the pop up and disabling it, it would just show up again

I disabled Caps Lock. Some games map stuff to it, or I'd hit it instead of Shift and then when I need to type I'm the shouting moron.

Disabled the fuck out of Caps Lock. Not that hard (for me) to just hold shift if I needed that many caps.

Sticky keys and the windows key I always immediately disable.

You guys are missing the true point of sticky keys:

Admin console without admin password.

The game is nazi zombies and you are on round 9267

People with disabilities exist, and they use computers too.

EDIT: love the unimaginative and annoying replies that rather than use their brain and contribute would instead throw insults. A person with low hand dexterity, like for instance people with paralysis, upper limb amputees of all kinds and people who use computers alternatively, like with their feet, or alternative keyboards and hardware adapters can initiate common key chords with this feature. For instance, common ones like ctrl+c ctrl+v, by pressing the key five times, then the letters. It is stopped by pressing the sticky key again. It's a good basic feature that enabled the use of computers for people who are usually ignored and undervalued by the tech industry. If you are a person with a disability you're likely to already know this while ignorant ableists, as in this meme, usually act as if it is some kind of alien function. It is not, people had to fight tooth and nail to get even this basic shit out the OS back in the day.

EDIT2: How about we all learn something new and interesting together instead of fighting.
