How To Fix – Windows is Not Genuine BUT IT IS

Windows_not genuine2A guy brought me his Windows 7 laptop because it was displaying a message claiming that the Windows version was not genuine. It was the original version that came installed on the laptop. So I figured it would just be a matter of clicking on the option to activate the system and that would be that. I came across a similar situation before on someone’s Vista laptop and that was all I had to do.

I got the product key off the sticker on the bottom of the laptop and followed through with the activation process but it kept saying the number was invalid. I double checked and triple checked the number and it was definitely the right one. I went online and found the following solution from:

It is possible that the Windows Licensing Store may be corrupt or unreadable. Try the following steps to recreate the Store:

Open an elevated command prompt: Type cmd in the search bar on the Start Menu, then right-click cmd.exe and select ‘Run as Administrator’.

You’ll need to hit Enter after each of the following steps:

  1. Type: net stop sppsvc (It may ask you if you are sure, select yes)
  2. Type: cd %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform
  3. Type: rename tokens.dat
  4. Type: cd %windir%\system32
  5. Type: net start sppsvc
  6. Type: slui.exe

After a couple of seconds Windows Activation dialog will appear. You may be asked to re-activate and/or re-enter your product key, or Activation may occur automatically. I still had to enter the number a couple of time before it went through. If all else fails, restart your computer and then try to activate. To finish I downloaded a program to back up the activation info and burned it to a CD, just in case.

*That backup program for your activation is called Advanced Tokens Manager –

  1. Some valuable info. I have dealt with this before, I usually just change the activation registry entry and reactivate over the phone.
