Your computer must have all the latest windows updates.  Keeping Windows up-to-date is one of the best ways to help keep your computer running well.  To make sure Automatic Updating is enabled to go to Start -> Settings -> Control Panel.  Double-click on the System icon and in the "System Properties" window, find the tab labeled "Automatic Updates" and click once on the tab.  Check the box next to "Keep my computer up-to-date."  Set the radio button next to the description that says "Automatically download the updates, and install them on the schedule that I specify."  Select "Everyday." The time you select can be whatever is most convenient.  Press the OK button.
