After using it for years I now get message on screen "Windows Vista Build 6002 This copy of Windows is not genuine "

cd   %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareLicensing

should all be on one line - even if it wraps itself (and yes, you need to hit the Enter Key after each instruction line) Make sure that there's a space between the cd and therest of the line, but no other spaces

The actual error message you got is interesting - as the dependencies appear to be the wrong way around.

Please run the following two commands and let me know what the response is

SC   QC   SLSVC

SC   QC   SLUINOTIFY

Noel,

Victory at last!  Many thanks.

After a couple of other false starts I managed to get the right spaces where needed. I had indeed missed the one between cd % and finally right at the end between vbs -rilc.

I finally got the desired message : License files reinstalled successfully.

The first time I restarted I got the validation box but no telephone option, so I entered the product keyand voila activation was confirmed. I closed down the computer a second time as instructed. On restarting The black screen came up but the message about this copy of Vista not being genuine had disappeared. I have now replaced the black with a more colourful background.

So your instructions were fine - it was just that I am not familiar with the computer commands and was in new territory and made some elementary mistakes.

One question : when I selected Yes in Step 5 did I remove anything important which needs replacing?

PS  I never ran the two last commands at the end of your last e-mail. Did you want me to?

Yes please - if only for my own peace of mind :)

You should also run a new MGADiag report and post the results, so that we can confirm everything is as it should be.

I have the same problem, but the sticker on the bottom of my laptop has worn and I can't see the product ID.

Any suggestions?
