Well, in the sense that many Windows users don't use the command line at all, this is true. However, startup time is a definite problem for Windows users who *do* use the command line, because process creation cost is a lot higher than on Unix, so starting new commands is *already* costly, and therefore minimising additional overhead is crucial. It's a bit of a chicken and egg problem - Windows users avoid excessive command line program invocation because startup time is high, so no-one optimises startup time because Windows users don't use short-lived command line programs. But I'm seeing a trend away from that - more and more Windows tools these days seem to be comfortable spawning subprocesses. I don't know what prompted that trend.
