Hi, The easiest way to control an executable like updaterui is via a group policy removing non-admin user's rights to the executable. Means it runs for admins and no-one else. eg. Edit group policy for terminal servers OU, Computer configuration > windows settings > security settings > file etc Saves rummaging around in the registry and gives you a global solution for all your TS servers. regards, Rick Ulrich Mack Volante Systems ******************************************************** New Site from The Kenzig Group VistaPop.com!
