How To Find What Service Pack Your Windows XP PC Has Installed

Follow these steps to find out what service pack is currently installed in your Windows XP system.

1. Click on Start and then Control Panel.

2. Click on the Performance and Maintenance link.

Note: If you're viewing the Classic View of Control Panel, you won't see this link. Simply double-click on the System icon and proceed to Step 4.

3. In the Performance and Maintenance window, click on the System Control Panel icon at the bottom of the window.

4. When the System Properties window opens it should default to the General tab. If not, choose it manually.

5. In the System: area of the General tab you'll find the operating system version and the service pack level. See the screen shot below for an idea of what you're looking for.

Note: If you don't have any service pack installed, you won't see "Service Pack 0" or "Service Pack None" - there will be no reference to a service pack at all.
