What's Wrong?

When using claude code on windows within VS code, Claude pops up visible command windows when executing commands. This takes away user focus and prevents them from doing other work while claude silently works in the background. When creating a sub-process on windows, use the CREATE_NO_WINDOW to avoid popping up on the screen and taking away focus from what the user is working on. This is very annoying.

What Should Happen?

No visible window is popoed up when executing commands.

Steps to Reproduce

1) Ask claude to do something that requires Git or other command to execute on windows using VS code
2) Watch the command shell pop up for a few seconds, take away your window focus, and then the command window disappears
