1) I have a Toshiba laptop with Vista purchased in 2008 from the USA. I am now in Qatar (Middle East region) and want to do a clean install of Windows 7 (hopefully improve overall performance of machine). Local purchase of Windows 7 software says it is only for Middle East release and activation. If I purchase, install, and activate Windows 7 here in the Middle East, can I reinstall it again later in another country if needed, say the USA?
2) What is difference between this Middle East version of Windows 7 and a version bought in the USA?
