I am in "control" of a project designed to prevent unauthorized installation of software on our company's many computers. The OS ranges from Win 3.0 to Win 2000(?). I need to shut them down and make sure they stay shut down if they install a new program. I have developed a system that does the same -- by by-passing DOS -- but I have received only complaints from the compliant users who only had to boot their systems and wait for 5 minutes to do their job. I need a way to "catch" the new installations when they "happen". Using VB 6.0. Thanks in Advance.<br>
