Windows 7: OEM DVD and Windows 7 Upgrade License

24 Jun 2011   #21

Windows 7 Pro-x64

After reviewing the prices of an OEM and Upgrade level of the same version, I suspect MS knows it's going on. The Upgrade is $40-$60 higher than the OEM version but $100 less than the Retail version. I guess that's why they don't pursue it. They're making money over the OEM version. I wonder, does the Upgrade then become a Retail version that can be moved to another PC?

Still, if you find a wallet with money in it, do you return it or say finder's keepers? Life is full of "loop holes". What you do with them determines your path.

I'm off my soapbox now.

Interestingly enough, in the case of an upgrade of an OEM version with a retail upgrade licence the upgrade takes on the licence of the original install so would become a non transferable OEM install.

This is my understanding based on previous experience that I think still applies to current upgrades though I have not checked recently

But there's no OEM key or installation in this example--Only the Upgrade DVD/key on a new PC. If the OS is loaded from the Update DVD, will the Update key default to an OEM license? It would be interesting to see a MS Validation report after it's installed and activated.

Once you have Upgraded with a upgrade key, all support from OEM is lost.

If you upgrade from Vista OEM & Win XP OEM to Windows 7 all driver support should come from Microrsoft.Which is the biggest problem.

As mentioned, so long as you own a qualifing copy of a previous Windows version, you qualify for upgrade.

It does not need to actually be present on the machine to qualify.

A clean installation is often prefered many Users.
Especially if upgrade time comes with a complete new PC build & HD, and MS is well aware of this.
So there is some flexibilty if you wish to install completely clean.

If somebody knows how to decode the "Product ID:" shown on the system screen, that should tell you if your final installation is OEM, retail, upgrade etc. Mine shows
xxxxx-OEM-xxxxxxx-xxxxx. I did a clean install with an OEM (non upgrade) DVD. I know for XP that 3 digit group was different depending on whether it was retail (335), volume license (270), OEM (OEM). Anybody with a retail install should have the same 3 digit code for that second group of characters.
