Hi,
I purchased my U772 back in 2014 with Windows 8. If I recall correctly, it had ExpressCache software enabled to speed things up. Two years later I upgraded to Windows 10 Pro, and, as you can imagine, ExpressCache stopped working. And I haven't been able to relaunch it since. Now Windows 10 takes 1-2 minutes to wake up from the hibernation state. I don't necessarily need the ExpressCache - Intel RST (which seems easier to configure) will do, too. But I can't make it work either. Are there any widely known issues with these? Or I can just describe the issues I have with both...
