2. Reinstall KMS Key 

If the previous version of your OS had the KMS activated, this method could work for you. Here, we will first uninstall the service and then reinstall it. Follow the steps below to do so.

Step 1: From your Administrator account, go to Start, right-click and select Command Prompt (Admin) from the menu. 

Step 2: Type slmgr.vbs /dlv, hit Enter, and note down the details in the description window which comes up.

3. Disable And Renable DNS Host

When you try to activate the updated software, the wizard tool employs DNS to locate the corresponding machine that is running the KMS software.

Step 1: As Administrator, open up Command Prompt and enter regedit.

Step 2: In the registry, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform.

Step 3: Here, create a new DWORD value, namely DisableDnsPublishing and set the value to 1.

Step 4: This should disable the DNS publishing on your computer.

Step 5: Now, to re-enable the default behavior for publishing of KMS service records to DNS, set the value to 0.

Step 6: Upon completion, restart your computer and check if activation is facing any issues.
