If you are experiencing this error on your system, the following solutions may help you:
1] Run the activation command in the elevated Command Prompt
The slmgr.vbs is a command-line licensing tool that you can use to configure licensing in Windows devices. It also helps to see the current licensing status of your Windows 10 installation. Many users do not know that Windows license activation requires administrative privileges. They enter the command slmgr.vbs -rearm to activate the product key or to expand the expiration time of the Windows server by launching the Command Prompt in normal mode. This is the reason why they get this error. If you are making the same mistake, try to execute the command in an elevated Command Prompt. To do so, type cmd in the Windows search box, right-click on the Command Prompt app, and select Run as administrator. If you get a UAC (User Account Control) window, click Yes.
