Quandries in OS for new build Tags: Windows 7 New Build Memory Last response: November 14, 2012 11:56 AM in Windows 7 Share hogwallow November 14, 2012 11:22:44 AM My existing PC has Windows 7 Home Premium, 64-bit on it. I'm building a new machine with 32GB of memory so need to upgrade and have a few questions: 1. I'm inclined to go with Windows 7 Professional 64-bit rather than Windows 8 because it's probably going to have more stable drivers across the board at this point. Is that the right thinking? 2. Can I install the new Windows 7 Professional just using the key and disk from Home Premium or do I have to install Home Premium first and then upgrade? 3. If I have to do the Home Premium install first, will the OS immediately recognize the additional memory once I perform the upgrade to Professional? 3. If I upgrade, will my existing machine's license immediately die so that I can't operate both machines for an interim period? I'm disinclined to do the Anytime Upgrade route because with a home build I want to have the full disk handy. Any help appreciated ...

Need to buy a upgrade. 3)It might recognize it, but won't be able to use it. 3+)Is this a OEM copy or full retail copy. OEM can't be transfer. m 0 l Can't find your answer ? Ask !
