Apprehension among system administrators and other IT professionals about Windows XP SP2 creating compatibility problems has led to many companies holding back on the update. Well, of course, Microsoft think that this simply will not do, and as such have introduced an application compatibility testing guide.
Downloadable from Microsoft's Download Center, the application compatibility testing guide is designed to help administrators test and mitigate application compatibility issues. It is intended for networks of any size, and goes right into detail about just some of the terrible problems a badly planned SP2 install could bring.
