Troubleshooting: Windows 10 Activation Error Code 0X87E10BC6

After purchasing a Windows 10 license, you need to verify the product key to register the operating system. The validation process goes through the Microsoft activation server. If Windows has trouble connecting to the server, activation will fail and display an error code: 0x87e10bc6.

The full error message sounds like this: “Something has prevented us from communicating with our activation servers. Please wait a few minutes, then try again. Error code: 0x87e10bc6”. If you’re having trouble activating your Windows 10 license, learn how to fix the error here.

What causes Windows 10 activation error code 0X87E10BC6?

Poor license description handling: If you encounter this particular activation problem, you should be able to resolve it by running the Activation Troubleshooter and automatically applying the recommended solution. If this does not work, you will need to contact a Microsoft Live agent and ask them to activate the license key remotely.

Server Problem: If this error code occurs when you try to run the game through the Xbox application, likely, Microsoft is currently experiencing a server problem that is preventing users from validating their accounts. In this case, there is nothing you can do except acknowledge the server problem and wait for Microsoft to fix it.

These licenses are a remnant of an older version of the operating system: this problem can occur when trying to activate Windows 10 Home or Windows 10 home on a machine that previously had Windows 7 or Windows 8 installed. If this scenario applies, you may be able to solve the problem by trying manual activation with SLMGR.

Windows DVD Media Player Error: In some circumstances, you may make changes that affect your system’s ability to play traditional DVD content. If this scenario applies, the fastest way to solve the problem is to use system restore to return your computer to a healthy state.

Third-party firewall intervention: If you are using a third-party firewall, it may mistakenly see the Microsoft activation server as a suspicious connection and block communication with that server. If this scenario applies, you will need to remove the overly protective firewall so that your computer can resume communication with the MS server.

Outdated versions of Windows: It turns out that this error code can occur when you try to activate your Windows 10 license key on a computer with an assembly before 1809. In this case, you can only install it if you first make sure you have the latest version installed.
