If by "things" you mean customer software support then yes, but development environments work consistently and are dead easy to set up. YMMV if you work on MS tech (.net, etc.), I don't. TBH one of my main reasons to move to Linux a few years ago is because I was pissed off by this particular problem (how to do it + ok and now tell me how to do it on windows and why half of what you describe doesn't work).
