I just got Windows 10 and it's giving me a whole bunch of problems that really annoyed me to the point where I want to go back to Windows 8.1. First thing is that my mouse keeps showing the busy/loading symbol right next to it constantly. It just appears and disappears in like a split second. Every time it does this it messes up my computer in some way like if I'm playing Minecraft and I'm holding the W key, it would cancel the action of the W key so I can't even move forward. I've checked all solutions and I have like no back ground applications running besides Steam, Skype, Origin and Norton. The other problem is the fact that I can't download Minecraft Windows 10 Edition Beta. I redeemed my code and everything and I can't play it. Please help me with this.
