What did you do?

What did you expect to see?

Please may the GetConsoleWindow and ShowWindow functions be added to the Golang windows package?

What did you see instead?

The GetConsoleWindow and ShowWindow functions aren't currently functions of the Golang windows package.

You don't need to wait for these functions to be added to golang.org/x/sys/windows package. You can just add them to you own code.

But, if you want to contribute these functions to golang.org/x/sys/windows package, here https://go.dev/doc/contribute is how to contribute.
