For laptop user's also check the bottom of the laptop, sometime the key is inside the battery case and you may need to remove the battery.
As of February 6th, 2015 the Digital River links to the various versions of Windows 7 are no longer functioning, as an alternative (as long as you have your product key) you can use the link to Microsoft's Software Recovery
web page: **http://www.microsoft.com/en-us/software-recovery**
Note: You may receive a notice to contact the PC manufacture if you have an OEM key that came with your computer, but it can't hurt to try. Also note that this site may return an incorrect language for the product key you entered. Please
read the wiki articles listed below as a possible solution.
Additional information and alternative resources:
If you have a friend with a "Retail" version (Full or Upgrade media,
just the media as you don't need their key) of the installation DVD (must be the same as your key was for: Home Premium, Pro or Ultimate) it will work with your
"Retail" or "OEM" product key if you need to re-install or repair Windows.
