Could be a problem Mouse related! I use an Logitech Wireless Mouse (because my HP WiFi Mobile Mouse didn't works on Windows 10, could not pair)! Maybe you guy's try an different Mouse if you have!
Let's say ms release win10 for public 2day. I have a legit win 7 key and i want to install (clean install not update) win 10. Any idea if submitting the win 7 key, m$ will give me an upgrade key for win 10? Or is a must update process from 7 to 10? Because i don't want to install win 7 to update from it to 10. If you know something.... Thanks !
the only one sure you will get free upgrade if understand very good ...now about new key for upgrade i think we all got same key for upgrade cauze its not possible share 1 million diffrent keys in 1 million devices
