Xp sp2

When I let SP2 install. It seems that I lost access to simple programs. Such as notepad and other type of programs found in the system32 folder. I also had difficulty accessing certain items under administrative tools, event logger and such. After uninstalling SP2 everthing was fine again.

About the only thing I can think of is that I was logged in as a user with administrative powers but not as the administrator. Any advise would be appreciated.

Thanks……..
