How do you transfer Windows 8 licence to a new machine

I upgraded an old low spec machine from win 7 to win 8. The pc is old and whilst Win8 runs ok I have purchased a newer higher spec machine which I wish to transfer the license to. I will not be keeping or selling the old machine.


There is a chance after running the upgrade assistant that the new machine may have issues which would aborting the install.


Could anyone advise the best process to go about this please. The same question would also apply for instance is an existing machine died and wanted to reuse the licence on a new machine


Thankyou in advance


Phone activation is not available on the weekends, its best you do it during the week.


If don't want to format the old machine, then its best you just uninstall the license just in case you decide to go back to it.


Press Windows key + X

Click Command Prompt (Admin)

At the command prompt, type: slmgr.vbs -upk


Hit Enter, this will uninstall the product key from the computer and set it back to trial mode, you are now free to use it on another computer.
