Hello, could someone let me know if it is free to upgrade Vista to Windows 7? and where can I download the upgrade/installation file?
The free upgrade offer oinly covers certain models purchsed shortly before Windows 7 came out, say, last summer. If your computer is older than that you may have to purchse Windows 7. To see if you are eligible for an upgrade the best thing is to check the manufacturer's Web-site or enquire with their support. The manufacturer may be able to send you a installation CD if you are eligible.
Vista to 7? Significant. Less resources. Better memory control. More built-in driver support. 64-bit better (new standard) than 32 bit version. But still best to roll it back to XP.
Some computers, especially "business class" ones, came with "downgrade rights to WinXP". If you have one of those, contact your computer maker and they should be able to provide you with an XP installation disk... you'll have to do a fresh install, however. If that's not the case, you can buy a retail version of XP. It will be transferable to a different computer if you wish... unlike an OEM version which is "tied" to the first mobo it's installed upon.. theoretically.
