How to fix the Windows activation error: Error code 0x87E10BC6

Error code 0x87E10BC6 appears in Windows systems when attempting to activate the operating system and indicates a problem connecting to the activation servers. It can occur in Windows 7, Windows 8.1, Windows 10, and Windows 11 —in both Home and Pro editions. Although the message may seem vague, its causes and solutions are well-documented in most cases. In this article, we present a comprehensive, step-by-step approach to resolving this issue.

1. Check your internet connection

The most common cause of error 0x87E10BC6 is an unstable or inactive internet connection.

What to do:

• Make sure your computer is connected to the internet—preferably via a wired connection (Ethernet) or a stable Wi-Fi network.

• Try visiting a few websites (such as google.com or microsoft.com) to make sure your internet connection is working.

• If you're using a firewall or antivirus software, temporarily disable them and try activating again.

2. Run the activation troubleshooter

Windows includes a built-in activation troubleshooting tool that can automatically detect and resolve most issues.

How to get started:

1. Go to Settings > Update & Security > Activation

2. Click Troubleshoot

3. Follow the instructions on the screen

This tool can reset the connection to the servers and fix activation configuration errors.

3. Change the product key to the correct one

Error 0x87E10BC6 may be caused by an invalid product key or an incorrectly assigned system version.

What to do:

1. Go to Settings > Update & Security > Activation

2. Click Change Product Key

3. Enter the key you received from Key-Soft.pl that corresponds to your version of the system (Home or Pro)

4. Click Next, then Activate

Make sure you enter the key correctly—without any extra spaces or typos.

4. Check that the system version matches the key

Some product keys work only with specific editions of Windows—for example, Windows 10 Home cannot be activated with a key assigned to Windows 10 Pro, and vice versa.

Solution:

• Go to Settings > System > About and check the name of the system version.

• Compare it to the type of key you have.

• If necessary, reinstall the system using the version that matches your product key.

5. Reset the system activation settings

In some cases, the problem may be caused by corrupted system files responsible for activation.

Step by step:

1. Open Command Prompt as an administrator

2. Type the following command and press Enter:

   Arduino

   net stop sppsvc

3. Next, type:

   SQL

   net start sppsvc

4. Try activating the system again from the settings menu

6. Run a scan of system files

If the problem persists, you should scan your system for corrupted files.

How to do it:

1. Open Command Prompt as an administrator

2. Type:

   bash

   sfc /scannow

3. Wait for the process to finish, then restart your computer

7. Reset your network settings

An incorrect network configuration can also prevent the system from activating.

Instructions:

1. Open Command Prompt as an administrator

2. Enter the following and press Enter:

   Perl

   netsh int ip reset netsh winsock reset ipconfig /flushdns

3. Restart your computer and try activating the system again

8. Install the latest Windows updates

Failure to update Windows may result in incompatibility with Microsoft activation servers.

Step by step:

• Go to Settings > Update & Security > Windows Update

• Click Check for updates

• Install all available updates

• Restart your computer

9. Contact technical support

If none of the above methods work, we recommend contacting Key-Soft.pl’s technical support, which will help you select the correct key, verify that your configuration is correct, and suggest a customized solution tailored to your version of Windows.
