Which shell are you using, cmd.exe?
Did this work previously?

I use the default windows terminal option cmd.exe. I cannot say if it ever worked.
Today, after having updated my insider build, Backslash works, strange....

Actually I would like to use VSCode as my Haskell IDE....
But when starting the Haskell Interactive ghci via "stack ghci", it does not accept Backslashes.
So no Lambda can be defined interactively.....

starting "stack ghci" in cmd directly, lets my input backslashes.
