Minecraft isn't working ever since I updated to windows 10?

You went to device manager then clicked updated? That doesn't work if so. Visit the manufacturer's web site and download the latest driver for your PC's model number.

Your not the first person here in YA who is having these problems with minecraft in win 10… Game problems / video card drivers that will work with that game problems… Yada yada…

Windows 10… Eh-h-h-h… If you look at it… It is still in the beta testing stage… For some… No probs… For the rest of the planet… Lots of problems… Check the minecraft forums… See what is up… Or-r-r hope that in the near future microsoft will fix the bug…
