Dear All,
I am currently joinedas a Lecturer In I.T and managing a computer lab also. But what happened is My senior left the job and installed Administrator password in almost all systems. I'm using windows Xp OS.When i contact him he told me that i forget the Password.Due to Administrator password privilege i won't able to install any new software.
I don't want to format the system.
Is there any way to install any software without giving the administrator password privilege.
All system is standalone PC. No networking.

Any Help?
