Trying Windows 10 Tech Preview? Keep these 7 things in mind
6. It’ll put a crimp in your entertainment options
Installing the Windows 10 Technical Preview disables the PC’s ability to play DVDs using Windows Media Player, and it removes Windows Media Center from PCs running Windows 8 Pro with Media Center. It’s not clear why this is. Maybe Microsoft wants you focused on the testing, and not spending time watching movies or listening to music.
Its technically an alpha - not even beta quality software.
Use at your own risk.
