Hi Dale Walsh,
I understand how concerning this is, especially when systems that have been working for years suddenly begin reporting that Windows is not genuine.
Since both computers are showing similar activation messages, it would be helpful to first confirm the current licensing status and identify whether Windows is detecting a blocked product key or another activation-related issue.
Please try the following checks:
- Open Command Prompt as Administrator.
- Run:
slmgr /dlv - Then run:
slmgr /xpr - Take screenshots of the results and share them in your reply.
Also check that the system date, time, and time zone are correct on both computers, as incorrect settings can sometimes affect activation validation.
If the output confirms that the product key has been blocked, please let us know:
- Which edition of Windows is installed (for example, Windows 7 Professional or Ultimate).
- Whether the license was purchased as a retail copy or came preinstalled with the PC.
- Whether any hardware changes were made before the issue started.
These details will help determine the most appropriate next steps and whether additional activation assistance may be required.
