I Recently purchased an ACER AX3475-EF328 WINDOWS 8 COMPUTER. I found i was not comfortable with Windows 8 so i tried downgrading the unit to Windows 7. So i grabbed my old Windows 7 DVD popped it into the drive and tried booting to the CD. But it didn't work. What's going on?? After several attempts of checking the BIOS i found the BIOS simply would not recognize the OPTIC Drive. So i called Acer technical support. What i learned is that Acer has done something within the BIOS to disable it from reading the optic drive. So the owner cannot load any other operating system on the unit. Acer Tech support and they said and i quote
"In order to downgrade to windows 7 or any other os we (Acer) need to make changes to the unit, and that is billable $99.00"
What Acer is implying is that Acer is renaming its brand to AT&T and now locking its computers similar to cell phone carriers and the only way to install a different Operating System OS is by paying Acer to unlock the unit!
SHAME ON YOU ACER! BUYERS BEWARE!!!
You can delete this post from this forum but I will be posting this on many more forums until you act responsibly and return to selling computers free for all to use with any operating systems!!
