Assuming that the popup window is part of your assembly, just keep track of a reference to it when you create it on the first click and on the second click just change the WindowState of the reference, like:

frm.WindowState = FormWindowState.Normal

If the popup window is an external app you can get a handle to it via FindWindowEx and then call SetWindowPlacement. They're both Windows API methods that can be called via PInvoke. More information can be found here:
