I have W XP Home edition. Clicking into Support > Windows Updates I find I have seven updates which Microsoft considers are Critical and recommends downloading / installing and gives me the Option to do so. Meanwhile I have an Icon in the Taskbar which comes on every time I go into the Internet - which isn't often-which when highlighted shows a "Windows Update" and is a percentage which is very very slowly increasing. It is about 50% at this time.
Can anyone tell me what the difference is between specifically downloading programmes via Update, and just leaving the computer connected to the Internet to download these percentage Updates ? I do not have downloads as a schedule as I prefer to be in control of the time element they take.
