About six months ago a Windows update was automatically installed and corrupted the Windows Registry. With the help of Microsoft the problem was fixed using a Startup Disk. When I asked should I download the update again, Microsoft advised the decision is up to me whether I want to risk it or not. Since this incident I have not downloaded any updates as I don’t want to risk going through this trouble again. Do you know what could have gone wrong? Also, when installing programs the installer often requests that I close any running programs. Does this mean I need to close programs such as Norton Internet Security as well? The computer is running Windows Me, with automatic updates configured to ask before downloading and installing.
