What Does the 0x87e107f9 Error Indicate?

Users have recently been experiencing the Windows activation error 0x87e107f9. This can result in a variety of issues. Users with an unactivated copy of Windows will have access to a limited set of capabilities. Due to this, users will be unable to use most customization options.

Users of Windows cannot alter the wallpaper, personalize the lock screen, or change icons, among other things. The most significant downside is that an unactivated Windows machine cannot receive the most recent security patches and feature updates, which puts the system at risk and makes it unstable.

After you do any of the following tasks on your computer, Windows is deactivated:

  1. Windows 11/10 fresh install
  2. Motherboard/Hardware Replacement
  3. Using a third-party security program
  4. Using a product key that isn’t the original

Disable your third-party antivirus product before attempting to fix the issues listed below. External security software has a history of interfering with and corrupting system software. Disabling it will make it disappear, and you should be able to solve the problem quickly. You can use the System File Checker application to fix corrupted system files and folders.

Before you try the remedies below, try the following, and see whether you can successfully activate Windows without problems after each task:

  • Delete the SoftwareDistribution folder’s contents. The SoftwareDistribution folder is an integral part of Windows Update, as it stores files needed to install new updates temporarily. Booting into Safe Mode is the safest approach to clear/delete the contents of the SoftwareDistribution folder.
  • Disable AV/Firewall for the time being. The activation procedure may be hampered if you have third-party security software installed on your device. If this scenario applies to you, you can temporarily disable the AV/Firewall and then re-enable system protection once the activation is complete.

Use the Windows Activation Troubleshooter

If you recently made a significant hardware modification (such as replacing the motherboard) or reinstalled Windows, the inbuilt Activation Troubleshooter may be able to help you reactivate Windows 11/10. You must be logged in as an administrator to use this automated tool.
