I like W-10 so far but I'm not secure enough to put it on my DAW. I thought I had a problem on the lappy but a reboot and W-10 fixed itself. It really seems to be a jam up OS. Just study up on the security options, there are tips all over the tech sites.
I'll likely update my DAW sometime in the spring... it's nothing I can't wait to do, W-8.1 is working just fine. I figure everything should be up to speed by then. I updated the Line6 driver last week and the UX-2 works good with W-10, the Octa-Capture, I haven't tried but I think it was Fireberd who said his Octa and Studio-Capture were both working on W-10.
You cannot stop technology, like someone said, "you roll with it, or it will roll over you".
I don't intend to be an old guy driving a 30 year old Buick with a 50 year old hair style... same with technology and other things. I think deciding you're going to like something before you get it helps a lot. Like when I went from lined bifocals to progressives... I was told that a lot of people had trouble adjusting and brought them back. I decided that I was going to like them, I got them and never looked back. Never had a minute's trouble adjusting. It's like that with the new Windows UI, you can still get the old desktop, IE is still there (I tried EDGE but it rearranged my favorites and I don't think it is as secure). Metro never bothered me in W-8, I just click and get the desktop if I want it or use the tiles if I want to. I think all the drivers will soon work and from what I hear W-10 isn't nearly as picky about drivers as previous Windows OS'.. and you have a 30 day window to roll back to 7, but don't look back... just do it, when you get ready.
I DO like it better than W-7, it's about the same as W-8 to me as far as use... but I don't use 8 for general surfing.
Sooner or later you'll need to jump... you know that right? Safest... wait till after Christmas but make up your mind to like it and GO! That's my advice.
