What version of Go are you using (go version)?

$ go version
go version go1.11.5 windows/amd64

What operating system and processor architecture are you using (go env)?

go env Output
$ go env
GOARCH=amd64
GOHOSTARCH=amd64
GOHOSTOS=windows
GOOS=linux

What did you do?

https://gist.github.com/TKSS3/dde5491ba0d96ae8bff0b816dd4d9fbc

What did you expect to see?

Since the windows registry part is not being used if GOOS=Linux, I expected to see no errors and succesfull build

What did you see instead?

.\test.go:24:17: undefined: registry.OpenKey
.\test.go:24:34: undefined: registry.CURRENT_USER
.\test.go:24:82: undefined: registry.QUERY_VALUE

You need to lookup build tags. https://golang.org/pkg/go/build/

Name one file task.go, then put linux specific calls into task_linux.go and task_windows.go and it will choose the correct files to compile be convention, even without build tags.
