1.9.1445.0

Other Software

No response

Steps to reproduce

• Launch Windows Terminal Preview and ensure Terminal Preview is set as your default terminal
• Open a quake window
• Dismiss quake window with `Win+``
• Close initial terminal window
• Launch a ps1 file from file explorer

Since the quake window is the only open Terminal window, defterm launches into that instead of creating a new terminal instance.

Expected Behavior

A new terminal instance is created.

Actual Behavior

The quake window is opened and attempts to run the selected file.
