BurningSmileYou can just remove the xbox app
Open an elevated(Admin) powershell
Put the following
Get-AppxPackage *xboxapp* | Remove-AppxPackage
this has nothing to do with vsync being forced.
it's a part of dwm and it's essential to how dwm works - you can't get rid of it without getting rid of dwm (which is what Win7 + basic/classic does).
that said win10 shouldn't irritate anyone more than win8 did, because win8 forced dwm as well. in fact WDDM 2.0, which comes with win10, does fix a lot of the input lag issues without vastly changing how dwm works. also the anniversary update should fully address all of the issues that WDDM/dwm had in the past regarding bad max framerates with multiple displays with mismatched framerates (which i've detailed and dug into in a couple of posts here on TFTV).
