I've been running a genuine W7 system under VirtualBox for some years now and after I installed a couple of updates on it today on rebooting it I get a Not Valid message and now I am unable to validate it online. Anyone any idea how I might do this? Any search on Microsoft says get W10 or W11 neither of which I want or need. I only use this copy of W7 for a couple of things which I cannot do with native Linux.
Apart from upgrade is there any way to validate this system?
