I recently reinstalled Vista on my somone's laptop (full install not repair) as I had done previously on the same machine without problem using the same windows iso disc a few years earlier.Some extra info: Straight after installation I checked the version of Internet Explorer and it was IE7. Probably not relevant but The laptop is a Dell Inspiron 1720, intel core 2 duo, 2Ghz Ram and it came shipped with Vista 32-bit Home edition. Windows has been validated online with authentic windows key.However i dimly remember that Vista SP2 came with IE8?
