Hey everyone :-)
I would like to downgrade my Acer from Windows 10 to Windows 7. I have a windows 7 product key on the back of my Acer but was told by my Acer to contact the manufacturer as the product key is from there (pre-installed from purchase)..
Unfortunately, I've had windows 10 for 1,5 years now. I've been unaware of this as my younger sister accidentally accepted the installation when she borrowed my Acer and I haven't really used my Acer since as I have a Mac too.
Well, my sister would now like to play some old PC games that won't cooperate with Windows 10 and therefore I'm looking to downgrade. But I have no idea how?
I hope some of you might be able to help me out! Thank you :-)
