As mentioned, I don't think that's feasible. You need to be able to interact with the desktop in order to click buttons, enter text, etc. When a machine is locked, the desktop is unavailable. No automation tool that I know of can interact with the desktop of a locked workstation. As mentioned, the solution is to go with a virtual machine.
There is a free license, I believe, of VMWare that you can run locally. That is probably your best solution. You'll need to make sure you have a floating user license of TestComplete so you can put your license server on your local machine and have your VM reference it. But honestly, I don't know of any tool that will allow you to interact with an application on a locked desktop.
