Where does AU Stores Updates?
Normally, AU stores patches in C:\WUTEMP or C:\Program Files\Windows Update\wuaudnld.tmp while waiting to install the patches. Q. I see Error 0x80190194 in Windows update.log A. You can safely ignore this error, The error is logged when the Automatic Updates client tries to check the server that is running Software Update Services for driver updates that Software Update Services does not synchronize. Therefore, the AutoUpdate driver’s folder does not exist on the server that is running Software Update Services. Error 0x80190194 is actually an HTTP status code 404 (File Not Found). This code is returned to the client by the server that is running Software Update Services.
