Majority of SP2 updates come up as "failed" after installing S

[buckdog05]

I just installed Windows Vista SP2 from a CD Rom onto a Dell computer I had restored to factory settings. It said that SP2 installed successfully, but when I go into the update history, the majority of the updates on the day that I installed Sp2 show up as "failed." Is this OK since the computer does have SP2 and shows it when I go into the "properties" for the computer or should I try to reinstall SP2 or the failed updates?

Thanks!
