Windows-7 - 32-bit upgrade to 64-bit -
I have 32-bit Win-7 Home premium.
Is there an UpGrade to Win-7 64-bit Home Premium or PRO - without starting over and paying the full cost to MicroSoft?
"Branded" versions of Win-7 PRO -
these are sold at a much lower cost then the full system is advertised for.
Question: Is this "branded" Win-7 fully installable and usable
for my custom built desktop?
Any disadvantages in going this route?
Q: Can I upgrade from a 32-bit version of Windows to a 64-bit version of Windows 7 or from a 64-bit version of Windows 7 to a 32-bit version of Windows?
A: You can use the Upgrade option during Windows 7 installation, which preserves your files, settings, and programs, only if you're currently running a 32-bit version of Windows Vista and you want to upgrade to the 32-bit version of Windows 7. Similarly, if you are running a 64-bit version of Windows Vista, you can only perform an upgrade to a 64-bit version of Windows 7. For more information, go to Upgrading to Windows 7: frequently asked questions on the Windows website.
If you want to move from a 32-bit version of Windows to a 64-bit version of Windows 7 or vice versa, you'll need to back up your files and choose the Custom option during Windows 7 installation. Then, you'll need to restore your files and reinstall your programs. For more information about performing a custom installation, see Installing and reinstalling Windows 7.
