So far, I only had to upgrade a driver for a gaming controller. My games and other programs seem to working fine. I still need to try my Blu-ray disc writing software.
All-in-all, this was the quickest and easiest uprgrade/full install I have ever done. Thankful for that.
One thing I like off-the-bat was how easy it is to use the new-ish taskbar volume mixer for doing cover songs. I can have the DAW output to studio monitors while the youtube playback is going out to my desktop monitors with just 2 mouse clicks instead of opening several pages of settings like before on WIn 7.
That Windows 10 start menu is just awful though.
I would highly recommend the upgrade.
