• Your Windows build number: (Type ver at a Windows Command Prompt)

Microsoft Windows [Version 10.0.17134.48]

• What you're doing and what's happening: (Copy & paste specific commands and their output, or include screen shots)

I'm trying to use the color tool to change the color scheme. Whenever I execute it within cmd.exe, it does not exit. Also the effects (even with --both) don't seem to persist when I close the hung window and open a new one.

• What's wrong / what should be happening instead:

1. Color tool does not exit and freezes cmd

To repro:

cd Downloads
colortool.exe --both OneHalfDark

Please see attached screenshot:

Start by reproducing colortool.exe --both OneHalfDark from cmd.exe on Windows 10 build 17134.48 and observe whether the command returns and the color scheme persists in a new window. Done means colortool exits without freezing cmd.exe and the selected scheme remains effective after reopening the window; the issue names no source file or test.
