I know I have seen low fps in games and lag in windows response sometimes. drivers are not perfected yet. I ended up booting into window 8.1 now because I can push the system more in it then windows 10. Im also was having problems with streaming apps and the video freezing but not the audio. in windows 8.1, the same apps work correctly also for people that complain about privacy with windows 10. if you use google chrome and gmail with notification and google now. you dont have privacy, because the google notification system can read email and be able to show you statuses on shipments and appointments. so I dont think people should complain about windows 10 privacy when android devices can show that you been looking at porn on your computer and even suggest websites and stores to go to for porn on your android device. google now.... "I noticed you been going to pornhub. would you like directions to the nearest porn store?" and you have an appointment with your marriage consular
Dunno if has been reported, but on MDL forums a WMC patch have been released, it is based on build 10134 (the last build containing the WMC bits). Hopefully Microsoft will learn something: their DVD application on the store sucks, people used WMC for DVR and TV-tuner capabilities, not as DVD player...
