Hi,
I have some questions about the Editions of Windows 7.

I went to Microsoft Store, Tech Zone and Barclays to look at the prices of Windows 7 and saw this


Windows 7 Professional (Microsoft) Full Version - $299.99 (Rs.32998.57/=)
                                                                  Upgrade version - $199.99 (Rs.21998.68/=)

Windows 7 Professional (Techzone) - Rs. 19,500/=

Windows 7 Professional (Barclays) - Rs.20,250.00/=

What is difference between Upgrade Version and the Full Version ?
What does Techzone sell ? Full version or the Upgrade Version ?
What is an OEM version ?

from the microsoft website:

Upgrade Version
The Upgrade license is for PCs that already have Windows XP or Windows Vista installed. This version includes the same features as the Full Version license.

To upgrade an earlier operating system than Windows XP (for example, Windows 95 or Windows 2000), you'll need to purchase a full version of Windows 7. To upgrade a Windows 7 PC to a different edition of Windows 7, you can do it in as few as 10 minutes with the Windows Anytime Upgrade service.

Full Version
The Full Version license does not require a previous version of Windows to be installed on the PC. This version includes the same features as the Upgrade license.

What version does Tech zone or barclays have ?

Clearly the full version.

Clearly the full version.

Barclays/Tech Zone or both ?
but the barclays one says OEM in the title

OEM is a piece of software released to 'original equipment manufacturers', or OEMs for short, is usually identical to the same version sold to consumers in stores. They come without the fancy packaging or manuals, because they're intended to be used by computer makers -- folk like Dell, or your local computer company -- for installation on machines they build.

Going OEM is like having unprotected sex -- it's not something to jump into without first knowing the risks. The largest of these risks is that your OEM copy of Windows comes with a licence for use on a single machine (specifically, a single motherboard). You can reinstall it on the same computer in future, but only on that computer.

AFAIK, yes but if replacing with the same model in case of RMA then Microsoft should be able to help u out (u might be able to get away with the same excuse in case of an upgrade as well, but then u'd be lying which i cannot recommend ), just give them a call.

In case of an assembled machine with warranty, then the place u bought it from is responsible, but only in case of RMA, not upgrades. However, i wonder if local retailers, except a few, won't try to weasel their way out of that one!
