How to fix
Windows activation error 0x87e107f9
on Windows

Hello. After I got my new PC I started receiving a Windows activation error 0x87e107f9. The computer came with a full license, so how can I fix this?

Windows is one of the most popular operating systems in the world. People love it for its user-friendly interface, customization abilities, and built-in troubleshooters that can fix the most common Windows problems. However, some people start receiving activation errors after they start using their new Windows machines.

Recently, users started getting the Windows activation error 0x87e107f9. This can cause a number of inconveniences. An unactivated copy of Windows will give users access only to a limited number of features. This means that users are unable to use most of the personalization settings.

Windows users cannot change the wallpaper, customize the lock screen, change icons, etc. The biggest disadvantage is that an unactivated Windows computer is not eligible to receive the latest security patches and feature updates[ref en-1] which can put the system in danger and make it unstable.

In this guide, you will find 6 steps that will hopefully help you fix these issues. However, troubleshooting Windows activation error 0x87e107f9 can be a lengthy process so we recommend trying to deploy a maintenance tool like [d1].

Method 6. Contact Microsoft Support

If none of the above methods have helped you in resolving the Windows activation error 0x87e107f9, you might have a serious issue with restrictions and activation servers. When you register your Windows license for the first time, it associates itself with your computer’s hardware. However, if you have made hardware changes, such as replacing your motherboard, Windows might be unable to verify the validity.

A support agent from Microsoft might help you find the reason and remotely fix the problem for you. Try to contact Microsoft support via the official contact page.
