How To Create Sys Env Var Programmatically?

[Spoodles]

I believe there is NT documentation that claims this is not possible. I find that hard to believe.

Anyone ever found a way to create a true system environment variable, ie, not a user var or a process var, programmatically?

Thanks.

Course you can create them. It requires writing to the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment and then broadcasting a WM_SETTINGCHANGE message.

However, note that the new (or altered) system environment variable is not retroactive, i.e the new/altered value will only appear in processes launched after the change is made

That was quick. Thanks.
