I need to know if there is any way to delete all the instances of a given environment variable, this means from all users and from the system itself.
The problem is about a software update. I need to keep installed a software in 2 versions, the old and the newer one. During the go live weekend i need to make sure that the OLD Version environment variable is deleted from the system (User and system) and just create the new one.
The problem is that i can log in the system with the admin user but not with the real user, so if he has the environment variable in his profile is when i have the problem.
Is there any way/soft for this purpose?
Thanks a lot.
