Windows 10 is better than any previous version of the OS, it is faster and easier to get around from place to place within the OS. I upgraded immediately or very shortly after the 29th July. W10 has the same basic operating kernels as 7, 8, and 8.1 and so there is hardly any risk in upgrading to the new OS for Serato users as long as your PC is 100% compatible. I ran Serato DJ as soon as I upgraded long before Serato gave official support and with zero glitches!
