Windows Activation Code Displayed As All B’s


KB ID 0001115 Dtd 16/12/15

"Have you got one of those programs that gets the Windows key?", my college asked me the other week. I said "Just download Magic Jelly Bean", "Yeah I've tried that and is showing the code as all B's".

Activation key all Bs

I sent him some more links and got back to what I was doing. He was having no joy with any other software, so I wandered over to have a look.


As it turns out this is quite normal if windows was activated with a MAK (or Volume) key. You can determine this by running the following command;

slmgr /dlv

slmgr find windows version

You can see that this particular machine is running on a volume licence. You will all note that further down it gives you the last five characters of the actual key "3QVWK". To stop people just extracting a volume licence, once activated Windows removes the key. It takes the last five characters of the key and stores them in a file called 'tokens.dat', You will find it at


You will see the same information if you run the Microsoft Genuine Advantage Diagnostic Tool;

There is another curve ball as well, if you trawl the forums you will find scripts that will decode the registry keys that usually hold the windows key, like this;

script windows key

You will see posts that say, "no don't use that registry key 'DigitalProductID' change it to 'DigitalProductID4' and it will work". Well it does work! But sadly the key you get will not.
