I know this might sound uber cheap/choosingbeggar but from what I understand you can use Windows 10 unactivated but trading off customization. How ok would it be to use Windows 10 on an Insider build (particularly Release Preview for most stable build) on a daily basis? I know this will sacrifice privacy (which I'm partially ok with), but would this enable customization, or rather is this technically a workaround to activate Windows 10? Why not throw in Office Insider as well to complete the package? So not only you get a free OS but also comes with free Office which is a pretty sweet deal. Not that I want a free Windows 10, but I'm rather curious if people actually do this, and if so, what's it like?
