Hello weereXT,
thank you for posting on the Microsoft Community Forums.
Here are some steps you can try:
- Check Internet Connection: Ensure your laptop is connected to the internet as activation requires an active internet connection.
- Run the Windows Activation Troubleshooter: Go to "Settings > Update & Security > Activation", then click on"Troubleshoot" to run the Activation Troubleshooter.
- Sign in with the Correct Account: Make sure you're signed in to Windows with the Microsoft account associated with your E3 subscription. You can go to "Settings > Accounts > Your info" to confirm it.
Kind regards,
Lei
