The "product key already used" message in this thread typically means Windows believes the key is already tied to another PC or the wrong license channel was used. As suggested, Microsoft phone support can resolve many activation cases; ’s VM approach is a valid portability workaround when the license permits, but the license channel still determines what is allowed.

The following checks can be run locally from an elevated Command Prompt (right-click, Run as administrator):

slmgr.vbs /dli
slmgr.vbs /dlv
slmgr.vbs /xpr

Those commands report license status, the Channel (Retail, OEM, Volume) and whether the license is expired. Note the Channel and License Status fields — they determine the next steps.

What to do based on Channel:

  • Channel = Retail: generally transferable to a different PC. If online activation fails, run slui 4 to start phone activation and have proof of purchase available. Deactivate or stop using the old machine per the license terms before moving the key.
  • Channel = OEM: normally tied to the original hardware (motherboard) and not transferable.
  • Channel = Volume: requires the organization’s KMS or MAK activation — contact the IT/admin.

Do not paste a full product key into the thread. Posting the Channel and License Status (mask the key) or a short excerpt of the slmgr.vbs /dlv output will allow targeted advice. Note: Windows 7 reached end of support on January 14, 2020; official support options are limited.

Myself, I run Linux on my systems and run Windows in a virtual machine, which I can back up, export, reinstall on another system, or whatever, and to MS it looks like the same machine in all cases. So, I can run Windows in a VM on my workstation, or my laptop, or if I need a new machine I can move or copy the VM there without problems.
