How to reactivate your Unity license when you update/change Windows version
Raw
windows_update_unity_license_reactivation.md

Valid as of January 16th, 2022

  • Shutdown Unity Hub
  • Find the license .ulf file and delete it, it will typically be: C:\ProgramData\Unity\Unity_v5.x.ulf
  • Go to your account at Unity ID
  • Navigate to My Seats > scroll down to activations
  • Select your previous activation and remove it (note that this will not delete your license or seats! It will just deactivate the connection to your old-windows-version machine)
  • Now open Unity Hub and it will offer you to activate a free license, just cancel the prompt and proceed to hub main screen
  • Click on "Manage Licenses > Activate New License > Activate with a serial number"
  • Now copy your license serial number from Unity ID account's "My Seats" page, and that should be it!

Note #1: this official tutorial INCORRECTLY states that you should uninstall Unity, you don't need to, it's enough to just remove the license file.

Note #2: in case you get an INVALID LICENSE KEY in the last step it's probably because you didn't remove the activation in the previous step on Unity ID site
