updates fail

Hello,

Welcome to the Microsoft Windows Community.

Good morning. This error is commonly associated with a connection failure to Microsoft servers. I am providing a script containing all the necessary commands to fix the error; simply open Notepad, copy and paste the text below, then click "File" > "Save as" (saving it to your desktop as "wufix"), and under "Save as type," select "All files." Run the script as an administrator; simply right-click on it and select "Run as administrator."
