Windows needs to be activated.

When you see the message that Windows needs to be activated, it typically means that your copy of Windows has not been properly activated with a valid product key. Activation is a process that verifies that your copy of Windows is genuine and hasn't been used on more devices than the Microsoft Software License Terms allow.

If Windows is not activated, you may experience limitations such as a black desktop background and a watermark indicating that the copy of Windows is not genuine. To resolve this, you will need to activate Windows by entering a valid product key. You can do this through the System settings or by using the command line.

If you encounter errors during activation, such as error code 0x80070005 (access denied), it may indicate that you need elevated privileges to perform the activation. In such cases, running the command prompt as an administrator may help.

For more detailed troubleshooting steps, you can refer to the relevant Microsoft documentation.

Can you please type cmd in the search on the taskbar and hit enter to launch command prompt, then run the following command:

slmgr /dlv

Then share a screenshot please. Thanks!
