So with the announcement that Xbox App will be integrated into Windows 10, coupled with the fact Windows 10 will be available as a free upgrade to Windows 7 and 8 users, it seems Xbox is gonna get a free bit of marketing/promotion.

I wonder how easy MS will make it to sign up to an Xbox account, if once you have your email address linked you can just open the app and chose a gamertag and ban you have an Xbox live account.

Windows has had an Xbox app for a while now haven't they?

Yeah but it's on Windows 8 which has crap marketshare, and it's tucked away in the metro part AND you need to download it.

All 3 of these problems will be resolved. It'll be available to far more people, right there on the start menu/list.

Oh ok. 

I am pretty sure most PC people won't care since I am guessing its a live tile which I am also presuming that it can be easily removed for other live tiles like how it is in the beta

Basically, think of how many people are on Win 7 that open their start menu to launch, say, Microsoft Word. Xbox will be right there like that.

Oh yeah, you'll possibly be able to move the tile, not sure you can actually get rid of it from your PC tho, it'll always be in the list.

It could just as likely to confuse people actually. Expect many to try putting 360 and X1 games into their disk trays and opening the app only to find out they don't work on their PCs. 

Let's hope they really make this easy and straightforward what the Xbox app really is and isn't. That applies to Xbox Live on PC as well. You may get people making purchases for games on Xbox Live who get upset they can't play them on PC.

I'm not sure how significant that type of advertising will really be for Xbox, but it's certainly no harm for them to have some synergy between products.

I am pretty sure you can since the start menu is soo limited in terms of space and the Metro UI is disabled by default in windows 10

You may not be able to uninstall it but you can certainly keep it hidden without much effort
