Why don’t elevated applications receive environment variables set by non-elevated calling process?http://blogs.msdn.com/cjacks/archive/2008/10/29/why-don-t-elevated-applications-receive-environment-variables-set-by-non-elevated-calling-process.aspxI had a conversation with a customer (via email) the other day, and I wanted to to into a bit of detail here explaining what is going on.
