Since Windows 7 is on the bottom the key, which launches the supplied Windows DVD, ie it is the installing code, but not the activation code.
If you had bought a pc and there was installed activated OEM Windows version then the Windows will be automatically activated after the installation. Admittedly, sometimes it will take several days before it is activated. If You want use some other Windows version, You must use or other key or something else, to activate this version.
The auto activation only happens with Windows 8 and above not with Windows 7. Windows 7 activation can be bypassed when a factory restore is done because it preserves the activation due to Certificate + Key + BIOS.
If it is an OEM activated pc, then there isn't any location related restrictions.
But if You want to use RTM Windows version, then it need new key.
The OP have Windows 7 OEM and is reinstalling the same machine with Windows 7 so why does it need a new key???
