I hardly ever use it so just noticed it yesterday. Thought it was my keyboard but even the onscreen keyboard has it disabled. This is the weirdest thing I've seen yet in Windows 10. VS 2004 Build 19041.329 Works fine in Window 7 (of course!). Keyboard troubleshooter says nothing's wrong. Well, if even the down arrow key on the onscreen keyboard isn't working I have to disagree.
At your convenience...
I would try going to Device Manager, selecting the keyboard, right-clicking and selecting Uninstall device and then rebooting.
Oldnavy, the onscreen keyboard has the same issue which does not use keyboard drivers (far as I know). Dalchina, I'll try in safe mode as you suggested later on. Getting late for me. Thanks for the replies.

Yeah, it works in Safemode. Can't imagine a setting that would stop it from working in normal mode.
So, it's probably some software you're running.
I would start looking for stuff that starts automatically on boot.
Sysinternal's Autoruns is a good tool for that.

You can start by using the less technically daunting task manager Start-up tab and disable startups there.
Or simply try killing processes you know are 3rd party programs.
If you have any Autohotkey scripts running, start by disabling those.
After that, Autoruns (free from MS) exposes every startup- from drivers upwards- as OldNavyGuy suggested.
There are so many processes listed in Autoruns it's very hard to drill down to the issue. Someone posted the EXACT same problem on Microsoft back in April so I suspect it's something Windows 10 added in the last update. There's a bunch of programs installed by them on June 22 (without my knowledge) I don't care about. I was wondering why I was getting Xbox Bar notifications in Warzone recently. I haven't added ANYTHING that could control what keys work or don't work. I'll go through this guide later on. Looks promising. https://support.microsoft.com/en-us/...oot-in-windows
For this you shouldn't need to go as far as a clean boot. That's why I refrained from it.
If Windows was responsible, one might expect there to be more than just your post on this.
Well, I re-enabled everything but Futuremark System Info (very recently installed 3dmark) and voila! Arrow key works again. That is the last company I'd expect to cause an issue. (－‸ლ) They're going to have fun explaining that to me.
My arrow key was working before I wrote that but as soon as I posted it I doublechecked and it wasn't working again. Must be a delayed service or something. The search goes on...
Edit: Found it!
I used Yamicsoft Windows 10 Manager to toggle individual running services on and off. When I toggled it off the arrow key started working immediately. When I toggled it back on after about 20 or 30 seconds the down arrow key stopped working again.
It sounds like this person:

solved a similar problem by reinstalling nvidia drivers. (Although the explanation leaves a lot to be desired.)
You could try it. I suggest doing a Clean Install of the nvidia driver using the advanced installation option in the installer.
