or updates for other installed applications as well?
If it is just Windows Updates, then goto Windows Updates in the Control Panel and change they way they are downloaded. Mine is set to notify me when they are available, then I get to choose when to download and install them.
Updates for applications are more of a problem. You have to identify those applications first and then dig down into their options to turn off their automatic update checking. No easy job with, for example, Adobe products. I haven't yet found a way to turn that off.
I'm having and have had problems with scans and updates running behind the scenes that are slowing my PC way down. Updates are a particular problem because the cause hangs and lagginess on my PC without showing up in "task manager" or so it seems. Often these updates are not identified so I need to hunt them down to find out which one is causing the problem before downloading the software. Without running the task manager all the time, how can I identify these when they are functioning or calling for updates? Any "small" applications, gadgets out there on the Internet that might show these in real time? Something maybe for the desktop or browser.
