Alt button wants to be windows button!?

So i was working on a track, when suddenly my alt button change it's function an acts like the windows button, which funny enough opens start menu...

 

Although the difference is that start menu disappears when alt button gets pressed, but start menu stays open when windows key is the one being pressed.

 

Any methods to fix this? I need that alt button to change some thing in my equalizer.

 

Thank you in advance. 

Nevermind. I fixed it. Turns out my Razer Deathstalker software (synapse 2.0) was trollin' me..

Yeah I'm honestly not a fan of synapse 2.0 at all.

Switch the caps, job done!

Else check your keyboard settings because they don't automaticly change if you use a different keyboard.
