Did you notice that except for removing the first @echo off lines all the other changes are just adding a single @ before each command? echo off turns echo off for the current cmd.exe instance, @ turns it off for one line. @echo off is convenient and clean but there's no reasonable way to restore the caller's setting when you're done (yeah, batch is crap):

venv has got the same issue.

I can confirm, while this is pretty messy it is indeed the best way of doing this.

Can you please fill in a similar PR for venv? thanks!
