Windows 10 - Screen changes . Help

[EvooHD]

Hello everyone, i have this strange issue with my computer , when my  Desktop Screen just slides to new one.    Thats happens when i press something on my keyboard,  for instance today i was playing  some games,  and i pressed something and my game was gone and i was trow back to  Desktop Screen without  my  "Steam" oppened up.     

 

It`s like there is some kind of  feature in Windows 10 , thats allow user to switch between  Windows Screens , or like Multiple screens.    I don't know but, i need   Help to disable this feature cuz, i can't even normaly work on my computer or even play games.  

 

Windows 10 Pro  (64Bit)  

Version:   1709

OS Build:   16299.192

 

Thanks,  Evoo!

I Solved my self....

 

And seems like 20+ people doesnt know what kind of problem this is, so here is the answer,    Windows 10 has feature "Virtual Desktop"  or the  "Task View"
