Microsoft Windows XP - Is Something Missing Here? Sure, But You Can Add Hardware After SP2
Creatures of habit who recently upgraded systems to Windows XP Service Pack 2 probably adapt well to the large, advertised changes Microsoft warned people about. On the other hand, Microsoft introduced some small changes that they didn't discuss at length that might have you searching for alternatives.
One such change is that Microsoft removed the Hardware Wizard button from the Hardware tab of System Properties. While the removal may inconvenience you, you can work around it. If you must access to the Hardware Wizard, you'll need to access it by launching the Add Hardware shortcut in Control Panel.
