Microsoft regularly updates Windows to fix security flaws. These updates are critical. Without them, your computer could easily be attacked.
In software as large as Windows XP, it's likely that there will be security problems. That is certainly the case with Windows XP.
Your computer is probably set up to receive the updates automatically. The message you are getting means that the updates have been downloaded to your computer. It is essential that you install them.
You can search for updates manually. Open Internet Explorer.
Click Tools ->Windows Update. Let Microsoft scan your system.
In the left panel, you'll find three categories of updates:
- Critical Updates and Service Packs
- Windows XP
- Driver Updates.
The first should always be installed; the others are optional.
You should make the update process as automatic as possible. In XP,
click Start -> Control Panel
Double-click System
Select the Automatic Updates tab
Click the box next to "Keep my computer up to date."
Click "Automatically download the updates..."
Set a time when you're normally online.
Click Apply -> OK.
In Windows 2000,
click Start -> Settings -> Control Panel
Double-click Automatic Updates
Set a time when you're normally online.
Click Apply -> OK.
In Windows ME,
click Start -> Settings -> Control Panel
Double-click Automatic Updates
Select "Automatically download updates..."
Set a time when you're normally online.
Click Apply -> OK.
