We have supplied HP Desktops with Windows 7 Professional 32-bit operating system and customer wants Windows 7 Professional 64-bit instead of 32-bit.  I want to know leagal implications from Microsoft to migrate to 64-bit OS using 32-bit key.  Customer will use only 64-bit OS on the desktop.  Can we use the same OEM key provided on the desktop to register 64-bit OS also? 

Yes, you can, as long as you are using the same corresponding edition, the product key will work.

 

Which media should we use to install the 64-bit OS (OEM or Volume License)?

 

OEM and Volume Licensing are different.

 

If the customer wants to use Windows 7 Professional 64 bit, just use the corresponding 64 bit Windows 7 Professional media with the OEM product key on the COA sticker.

 

You will have to do a clean installation, there is no in place upgrade path from Windows 7 32 Bit to 64 bit.

Using the Windows 7 64 bit disk, install the Windows 7 Windows Easy Transfer Utility from the DVD (To find it, just navigate to x:\support\migwiz, 'x:' represents the name of your disk drive. In this folder, you will see a collection of files, the important one you need to look for and double click is 'migsetup'.) , run it and create a WET file (Windows Easy Transfer file), if you have an external hard disk, you can have it stored there so you can access it later when you do a clean install of Windows 7 64 bit disk.

Once you have done that, simply do a clean install of Windows 7 64 bit disk. In Windows 7 64 bit disk, launch Windows Easy Transfer, follow the on screen wizard, point to where you stored the the WET file (external hard disk), and it will restore your personal files and settings. Reinstall any necessary applications.

Volume license should only be used if the customer has a volume license contract and can only be used with a volume license product key.
