Issue: How to fix Windows activation error 0XC004F009?
Hello. I had my Windows laptop for a couple of months and I started receiving an activation error 0XC004F009. The update services have stopped working also, which is causing problems. What can I do? Any tips would be appreciated.
Microsoft Windows is one of the most widely used operating systems in the world. Even though people love it for its user-friendly interface, built-in troubleshooters, and customization abilities, it is not flawless. It is an extremely complicated system that relies on thousands of processes to keep it running smoothly. People can experience bugs, crashes, errors, and other issues, which is never a fun experience.
Some users have encountered a Windows activation error 0XC004F009 or otherwise known as the Grace Period error. The term means that all users who installed a copy of the Windows operating system, fall into the grace period. They can use Windows and all of the features without any restrictions. However, if you receive the Grace Period Expired error, you might be left with a system that does not function properly.
When the system starts showing users an activation error saying that it has expired, they can encounter a shutdown of some important functions, like the update service. This can make the OS unstable and vulnerable. The issue can be caused by many things and in this guide, we will present you with 8 solutions that could fix the Windows activation error 0XC004F009.
Manual troubleshooting can be a lengthy process so you can try using a repair tool like ReimageMac Washing Machine X9 that can fix various system errors, like BSoDs, registry issues, and corrupted files.

- Type in cmd and hit the Ctrl + Shift + Enter keys
- When prompted by the UAC, hit the Yes button
- Type in slmgr -rearm command and hit Enter
- Restart your computer again
- Repeat the activation process
Method 6. Use the Command Prompt to Activate Windows
- Take note of your MAK key
- Press the Windows key and type cmd into the search field
- Run the Command Prompt as Administrator
- Type in vbs -ipk <your MAK key> command and hit Enter
- Wait as Windows is being installed
- After that, input this command: vbs -ato and hit Enter to proceed
- Close the Command Prompt and restart your computer
Method 7. Use a Default Product Key
If none of the fixes above worked, you can try to use a default activation key. This is a generic key provided by Microsoft to resolve common activation errors. If you use it, Windows will activate temporarily. This is a temporary solution as you will need to replace it with a genuine key later on.
- Press Windows + I keys to open the Windows Settings
- Select the Update & Security option and then click on the Activation tab
- Under the Update Product key section, click on the Change product key
