A few days ago a Web Talk reader named Tad Ensign, contacted me explaining how to perform a full Windows 7 installation from an Upgrade. I have to tell you that at the time I was completely unaware of this issue and his brilliant solution left me amazed. Apparently, if you try to make a full installation of Windows 7 after formatting your hard drive, the system could return you with a message saying that the key is not valid…something like this: “The Software Licensing Service determined that this specified product key can only be used for upgrading not for clean installations” Here is the workaround to solve this issue. Thanks Tad!
- Install Windows 7.
- Do not Enter the product key during setup.
- Once setup has finished installing click on the Registry File Named MediaBootInstall.reg and it will Reset to a Full Retail Product. To create such a file, copy and paste the following code on your Windows Notepad. Name it MediaBootInstall and give it .reg extension.
- Click Start.
- In the Search field, type cmd and press Enter.
- In the Command Prompt, type In slmgr -rearm and wait for a message to popup. Reboot your Computer.
- Go to Product Windows Activation and enter your Product Key.
- Done, you just converted from upgrade to Retail install.
