Spent a frustrating morning at a friends where he'd done the Windows 10 upgrade to discover Cubase and Sibelius were now silent. The Lexicon advice was not to move to Windows 10, but too late. So he's now waiting for a nice red 2i2 to arrive. Annoyingly, he was at first pleased because the Lexicon driver reported just 5.2mS latency - which for him is important as he's concert pianist and latencies of more than 10mS wreck his playing. He got excited with the 5 figure, then discovered that Windows had de-activated it and the other possibilities on his system reported 20mS or more - totally useless to him. I think there must be quite a few Lexicon users out there (I have one myself in my portable Macbook rig) so Windows 10 isn't exactly hot off the press now. He uses his system for his work, so suddenly being unproductive is a real pain. He uses one of those new microsoft surfaces with score writer (or whatever it's called) on it, transfers those files to Sibelius for printing the band parts, and uses Cubase to produce his music for sale.
