It's important to install the security updates that Microsoft makes available at windowsupdate.microsoft.com/. This can keep you from being the victim of a hacker. Check this site often and install all Critical Updates. However, you're also given the option of installing Driver Updates. Since I was up to date on all critical updates, I thought I would download and install some updated drivers. Big mistake. One of the drivers was for my video card and the next time I rebooted the computer, my video card no longer worked. I spent a few minutes this morning with Gateway's tech support getting the driver changed back to the one I had before. Thanks, Microsoft, for providing an update that actually makes my computer stop working.So remember, get the critical updates, but pass on other updates from Microsoft unless you're sure you need them.
