How to fix 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 —both Home and Pro versions. Although the message may seem unclear, its causes and solutions are well documented in most cases. In this article, we present a comprehensive step-by-step approach to solving this problem.

1. Check your internet connection

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

What to do:

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

• Try visiting a few websites (e.g., google.com, microsoft.com) to make sure the internet is working.

• If you are using a firewall or antivirus program, temporarily disable them and try activating again.

2. Run the activation troubleshooter

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

How to start:

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 incorrect 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 assigned to your system version (Home or Pro).

4. Click Next, then Activate.

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

4. Check that the system version is compatible with the key.

Some product keys only work 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 system build name.

• Compare it with the type of key you have.

• If necessary, reinstall the system version that corresponds to your key.

5. Reset the system activation settings

In some cases, the problem may lie with damaged system files responsible for activation.

Step by step:

1. Open Command Prompt as administrator

2. Type the following command and press Enter:

   arduino

   net stop sppsvc

3. Then type:

   sql

   net start sppsvc

4. Try activating the system again from the settings.

6. Run a scan of system files

If the problem persists, it is worth scanning the system for corrupted files.

How to do it:

1. Open Command Prompt as administrator

2. Type:

   bash

   sfc /scannow

3. Wait for the process to finish and restart your computer.

7. Reset your network settings

Incorrect network configuration may also block system activation.

Instructions:

1. Open Command Prompt as administrator

2. Enter and confirm with 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 all of the above methods fail, we recommend contacting Key-Soft.pl technical support, which will help you select the right key, check the configuration, and suggest a customized solution tailored to your version of Windows.
