EAapp seems to mess up my computer booting, is steam a safe replace option?

Okay I have consulted the windows messenger bords before posting. Narrowing down the problem it could only point to the EAapp. Don't think thats a very strange thing to do if the only thing that had changed on a computer was that app. Also have read that I'm not the only one experiencing quite invasive effects from just a simple app, so that's why I posted it here.

Thank you for informing me about steam not being able to actually be used as a launcher and that I will still be redirected to the EAapp (and that the EAapp couldn't be that invasive that it would block my windowsuser boot up after I tried logging into it). Just to be safe (becuase again so far everything still pointed to the eaapp) guess that means no sims anymore for me.
