Free Upgrade to Windows 10
I'm reverting back to Windows 8.1 !
To many bugs for me atm.. The sound comes on and off when it chooses, drivers incompatible, Ill wait until they have ironed it out a little more.
I have a year to choose to upgrade it again, .. at least I think :P
For the sound issue, you might want to check this setting. Right click the speacker icon in the System Tray, click Sounds, then go to the Communication tab. Set it to Do nothing.
This was a horribly annoying issues for me in Win 8.1 and the setting reset when I upgraded to 10. Basically, it lowers your computer volume whenever you plug in headphones. Nice idea, horrible implementation.
