3] Check the status of some Windows Services

If you’re still experiencing the problem, you can check the status of some Windows Services and determine whether all the services are running. Follow the below steps to do this.

Open Windows Services Manager and check the Windows Update related Services like Windows Update, Windows Update Medic, Update Orchestrator Services, etc are not disabled.

The default configuration on a standalone Windows 10 PC is as follows:

• Windows Update Service – Manual (Triggered)
• Windows Update Medic Services – Manual
• Cryptographic Services – Automatic
• Background Intelligent Transfer Service – Manual
• DCOM Server Process Launcher – Automatic
• RPC Endpoint Mapper –  Automatic
• Windows Installer – Manual.

This will ensure that the required Services are available.

Apart from the direct service, you should find the dependencies of Windows Update service and ensure if they are running or not.

To get started, search for “services” in the Taskbar search box and click on the search result. After opening the Services window, find out Windows Update, DCOM Server Process Launcher, and RPC Endpoint Mapper. Check if they are running or not.

If not, you need to start those services one after one.

4] Use SLMGR command

You can try running the SLMGR commands on the elevated Command Prompt to deactivate, uninstall & reinstall the Windows Product Key.

Type ‘cmd’ in the search bar and then press Ctrl +Shift +Enter to open the Command Prompt with administrative privileges.

If UAC prompts on the screen, click ‘Yes’ to grant administrative privileges.

Now in the command prompt window, type the following commands and hit Enter after each command.

This will reinstall the key:

slmgr /ipk <Windows Key>

The following command will make Windows OS attempt activation:

slmgr /ato

In the above command line, don’t forget to replace the Windows Key with your license key.

Once you’re done, restart your PC and see.
