I ditched Windows 10 TP 10049 lasr night for good. It's really beginning to appear to me that Microsoft has lost it's focus, since 2015 got here. The 2 builds of Windows 10 have both had bug's that really shouldn't be there. Mail, Calendar & People haven't worked on either without the end user doing a search on how to fix them and then run a administrative PowerShell command to remove them and then go to the store and reinstall them, to get them working. Sorry, Microsoft, but instead of releasing new features first. How about making sure you're own old app's work first. The Store Beta app, absolutely suck's and fails to download/install any updates. Now I hear ProjectSpartan is going to be the default browser in the next build they release. Great, so we're basically being stuck with a updated version of modern version of IE, that no password managers, ad-blockers, etc. work with. No thank you Microsoft, from what I've recently seen, Windows 10 truly isn't a upgrade on any desktop or laptop. It's a downgrade, so far. SLI & Crossfire won't work and if you enable them, you're monitor stop's functioning. Funny how AMD & NVidia have no driver's for 10 and Microsoft give's us generic one's that don't work. I'm not at all interested in the Xbox app. I have no plan's to get a Xbox One, just to play mediocre looking Xbox games on my pc. I'd rather play pc games, that actually uses my hardware's potential. Wow, they dropped Xbox from the Music and Video app's. Big dal, both still suck compared to WMP 12 and WMC.
