When you run Windows Update, you will see the message “Installation failed, error code 800706BE.” It’s important that you download the latest version of Windows, because the previous version of Windows had a bug that prevented it from installing properly. To fix the error, follow the instructions in the message. If the error persists, try reinstalling your operating system. Hopefully, this will solve the problem.
