ZIP archive of about 1 MB containing a Windows Update blocker utility, a software tool rather than a schematic or firmware dump. The name gives no version number or source. Shops use this kind of utility after a repair to stop Windows from automatically installing drivers or updates that could undo a working configuration or reflash firmware. Scan the contents with antivirus software before use, and remember to re-enable updates when the customer needs security patches. It has no connection to any particular motherboard.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @CLRINDORE. Enginerys does not host this file.
