As others have said, you obviously don't understand the Windows security model.
An application, running as a normal user account, cannot do anything that requires administrative privileges.
And as for reboot messages, it IS the application that asks for a reboot, not the operating system itself.
Did you check that the application had done anything to actually require a reboot (file rename operation, installed a new service?) before coming on here and whinging about it? No, didn't think you did. As others have already said, check the Application log to see what really happened, rather than your worryingly inaccurate version of events. I too hope you don't actually work in IT.
