Hi, I had a weird font problem since Windows 8. I had the thread here, http://forums.mydigitallife.net/threads/60973-Windows-8-language-showing-all-weird?highlight= I thought, upgrading it to windows 10 will solve it, but it did not. What to do ? Boot to Windows 10 DVD again ? Will it again ask for the key ? And will it clean sweep my C drive ? So I have to install the apps all again ?
