Batch QZ Tray Session Stealer

Custom session stealer for Windows fast user switching

For a pure PowerShell solution, see here instead: https://gist.github.com/tresf/4e19e15ad38354af6732ee701c990102

Problem

• QZ Tray is a singleton application, so only one instance can run at a time.
• Windows fast-user switching feature leaves applications running when a new user signs onto a shared workstation
• QZ Tray can "steal" the instance, however this is retroactive and places a burden on the user
