Windows 10: Alt+F4 function happens by only pressing F4

I'm currently on windows 10 and whenever i press f4 it closes down the program i'm using. i don't think my alt key is stuck because it functions normally otherwise. i think it has something to do with my system or my settings but i don't know where to start. also i'm not sure what topic this falls under so forgive me if i put the wrong one.

Alt-F4 produces playlists

Hmh.. strangely enough, there actually is a playlist on Spotify named "alt F4": alt F4 on Spotify

But anywho, you wouldn't happen to have some sort of macro program open? Macro programs allow certain key functions to do other behaviors. For example, Alt+F4 can be redirected to do other functions (such as creating a new playlist).
I use Macro Express and have it running all the time.

Just a shot in the dark but does your keyboard have
1 Anything else marked on the F4 key?
2 A key labelled in blue as Fn / Function / similar

If so then perhaps you have accidentally triggered its change to Fn behaviour so that pressing Alt-F4 is being seen as Fn-Alt-F4 and responding to that other marking on your F4 key. The method for triggering & resetting this behaviour varies so you'd have to check
- Windows mobility centre interface, Function key row item [Enable Windows Mobility Center on a Desktop Windows 10 PC - TenForumsTutorials] - assuming that item exists on yours
- Your computer/keyboard manual
- Your computer/keyboard maker's support site / user forum.

Ctrl F4 & Alt F4 not functioning as Volume keys in Surface Pro 4, Windows 10

My Ctrl F4 & Alt F4 key aren't working. It appears the Ctrl and Alt Keys are not changing the function of the F4 & F5 (Volume on/off). How do I reset or turn the Ctrl and Alt functions back on?
