I don't really need this
I understand that Microsoft download the Windows 10 update files without PC owners being aware. I am custodian of a laptop belonging to our local U3A. The C disc is not very big and partitioned with windows 7 and windows 8.1 installed. The laptop is used at meetings, connected to projector and screen in order to demonstrate aspects of Win 7 or 8.1 which most of our members still use. These update files are not needed and are taking up room unnecessarily. Does anyone know how I can identify, locate and remove them, and take steps to inhibit further Windows 10 downloads.
