How to Fix Windows Genuine Advantage Error on Windows 10: Step-by-Step Guide

Windows Genuine Advantage (WGA) errors can be frustrating, especially when you know your copy of Windows 10 is legitimate. These errors often pop up unexpectedly and can interfere with your system’s normal functioning.

This guide will walk you through simple and effective steps to fix WGA errors on Windows 10. The instructions are easy to follow, even if you are not very tech-savvy.

By the end of this article, you will understand why these errors occur and how to resolve them quickly. Let’s get started on restoring your Windows activation status.

Follow each step carefully to avoid further issues and ensure your system runs smoothly.

Quick Note

Before you start troubleshooting, here are a few quick checks to make sure you are ready:

  • Ensure you have an active internet connection. Windows needs to verify your activation status online.
  • Check that your Windows 10 license key is valid and properly entered in system settings.
  • Make sure your Windows installation is up to date by running Windows Update.
  • Back up any important files to avoid accidental data loss during troubleshooting.

Step 1: Restart Your Computer

Sometimes, a simple restart can fix temporary glitches that cause WGA errors. Restarting refreshes system processes and clears minor errors.

How to do it:

  1. Click on the Start menu in the bottom-left corner.
  2. Select the Power button.
  3. Choose Restart from the options.

After your PC restarts, check if the WGA error still appears.

Step 2: Run the Windows Activation Troubleshooter

Windows 10 includes a built-in troubleshooter that can automatically detect and fix activation problems.

Follow these instructions:

  1. Open the Settings app by pressing Windows + I.
  2. Click on Update & Security.
  3. Select Activation from the sidebar.
  4. If you see an error message here, click on Troubleshoot.
  5. Wait as the troubleshooter scans your system and applies fixes.

The troubleshooter can resolve common activation issues by refreshing your license status.

Step 3: Check Your Product Key

An incorrect or missing product key can cause WGA errors. It’s important to verify your Windows product key.

To verify your product key:

  1. Open Settings (press Windows + I).
  2. Go to Update & Security > Activation.
  3. Look under Product Key or Activation status.
  4. If your key is missing or invalid, you can enter a valid one by clicking Change product key.

Important: Use a genuine product key purchased from Microsoft or an authorized retailer.

Step 4: Manually Reset the Windows Activation Files

Sometimes, activation files can become corrupted. Resetting them can help fix the WGA error.

Here’s how to reset activation files:

  1. Press Windows + X and select Windows PowerShell (Admin) or Command Prompt (Admin).
  2. Type the following commands one by one, pressing Enter after each:
net stop sppsvc
cd %windir%ServiceProfilesNetworkServiceAppDataRoamingMicrosoftSoftwareProtectionPlatform
rename tokens.dat tokens.old
net start sppsvc
slui.exe

This process stops the Software Protection service, renames the corrupted tokens file, restarts the service, and opens the Windows activation window.

Follow the prompts to activate Windows again.

Step 5: Update Windows to the Latest Version

Outdated versions of Windows 10 may have bugs affecting activation. Keeping your system updated ensures you have the latest fixes.

To update Windows:

  1. Go to Settings > Update & Security > Windows Update.
  2. Click Check for updates.
  3. Download and install any available updates.
  4. Restart your computer if prompted.

After updating, check if the WGA error persists.

Alternative Method: Use the System File Checker Tool

If the problem continues, corrupted system files might be the cause. The System File Checker (SFC) scans and repairs these files.

To run SFC:

  1. Open Command Prompt as administrator.
  2. Type sfc /scannow and press Enter.
  3. Wait for the scan to complete. It may take some time.
  4. Restart your PC after the scan finishes.

This can repair damaged system files affecting Windows activation.
