[bagus.laksono () indofood co id]

Hi..

I am new in it- security especially in computer security, currently  I have
problem to controlling many pc & notebook users wiith most operating system
used are Windows system (Win 98, 2000 and XP). Can anyone help me to find
the solution of how to restrict or avoid users to installing any
application from windows registry ?
Any help or advice is appreciated..

Thanks
