Hi, I'm John! I will help you with this.
Which which specific update (KB number) is failing to install? And what specific error message are you seeing?
Also, could you provide me with a screenshot of your current Windows OS Build?
To do this, press the Windows key + R to open the Run dialog, type winver and press Enter, capture a screenshot (make sure not to include your email address), and attach the screenshot in your next response.
