It is the Steam ingame Community overlay. Totaly harmless.
When playing games on steam, the shift-tab function is what the process really is. It's absolutely harmless.

Used for Steam games, harmless.
It is ingame steam community overlay.
It is what lets you press Shift+Tab whilst in a Steam game and use Steam within a game. It is totally harmless and is infact quite crucial to Steam.
to open steam ingame ALT + TAB
Its definitely a process for Steam, and it's no more dangerous than microsoft word.
I think it has to do something with a steam update

Totally harmless, it's an official Steam overlay app.
Steam Overlay when playing Steam games. Completely harmless and somewhat important.
Steam's in-game overlay servie. Rarely breaks, completely harmless and unless you know what you're doing, dont kill the proccess. Make sure it IS the actual in-game overlay .exe though, there are some malware that disguises itself has this.
  Some dude from the internet.  
CSGO skin stealer! ***End process immediatly!!***
It's used for the Steam Community gaming software, however a problem I had with it was that I had to open steam multiple times earlier, due to system difficulties, and it opened 3 copies of this overlay, using up 25 CPU each. Lagged my games a lot, you should check how many processes of this you have open.
This is the program used when in-game, by pressing Shift+Tab to open to open the Steam Community page People who say it's dangerous are just being rude, if you close the program through Task Manager while in-game you will find that you can no longer use Shift+Tab (in case you don't believe me) and anyone who says this is harmful is just trying to mess with people
  I dont have a name  
Just the Steam overlay when you're in a game. Nothing to worry about.
