Ease of access

Hi, which OS are you referring to please? 'My Computer' shows Windows 7, as does the text under your avatar. If Windows 7, I recommend sevenforums.

Are you running Home or Pro?

What does the NoWinKeys key do?

It disables all hotkeys, past and future (since they keep piling up). Mostly combos like: Win + R.

Hardcoded keys will always work, like ALT+F4 or CTRL+ALT+DEL.

That's not directly related to those Accessibility settings though, right?

No, but some people find them annoying. I think, it also disables sticky keys, but I have not tested it.
