Problems with the elicenser component attached to my Steinberg UR44 interface. It says I don't have the required permission to run the software. Not ready for win 10 by the looks of it.

Have those who are experiencing driver issues tried reinstalling drivers and such in compatibility mode?

I'm trying to find out if the following are working on Windows 10
- M-Audio Keystation 88
- Samson Studio GT (The USB monitors)
- iLok 2

I'm back in the game. The Steinberg UR44 interface is tied into the elicenser system just like an ilock. Why, I'll never understand. Maybe they think I'll make a pirate interface. At any rate, I went through the license process again and it unlocked the interface.

Yah looks like drivers will be the hangup for now. But looks like manufacturers are rolling them out at a decent pace. 

I checked my East West Symphonic Orchestra and Synthology's Ivory II programs, both worked fine...Ilok doesn't seem to want to work but it isn't stopping those two programs from working. Go figure.

I was able to downgrade back to Win 7 successfully.

So it's the same as any other windows release. I do have sympathy with MS as third party drivers issues is always the problem. I also have sympathy with third parties making the drivers who don't want to waste resources developing on a moving beta platform. Good news is it will all probably be OK in 3 to 6 months. It's just a waiting game mainly. Some will be lucky straight away others not so lucky.

With the way MS is dealing with privacy, it might be an idea, too, to wait for these issues to get cleared up. It almost sounds like offline computing will be difficult if not impossible without risking being blacklisted regarding security updates.
 
I'm still reading reports trying to sort it all out, but for now, no Win10 for me.

Actually this release was more trouble free than any of their other releases. It went rather well for me as about 99% of everything worked fine on first try. I'm quite pleased with it. The speed of the Edge browser, the new Start button layout, the Start page, make it all worthwhile. You can customize the Start button's layout and man is that nice !!!
