Answer 2

Hello,

Thank you for posting in Q&A forum.

An error occurred with our activation server or licensing service. Wait a few minutes and then try the following Select the Start button, then select Settings > Update & security > Activation , and then select Troubleshoot to run the Activation troubleshooter. When the troubleshooter is complete, select Go to Store to launch the Store app. If the Store app shows there was a problem, select Try again. After a few minutes, you should see a message thanking you for activating genuine Windows, followed by another message showing that Windows was activated.

For more info about the troubleshooter, see Using the Activation troubleshooter.

I hope the information above is helpful.

Best regards

Zunhui
