So many points, and almost all of them wrong
First of all, Linux isn't a clone of MINIX, Linus just used MINIX when he was writing Linux and used some of its POSIX documentation as a base for writing the POSIX layer in Linux. A lot of the early ideas in Linux are borrowed from MINIX, but just as many aren't, and the current versions of Linux and MINIX are completely different architecturally. If anything, Linux borrowed more heavily from UNIX than it did MINIX. Shall we next perhaps discuss how Microsoft borrowed most of its GUI from Apple, who in turn borrowed most of their GUI from Xerox (implemented on top of UNIX naturally)?
On the topic of OS X to even suggest that it stole ideas from Vista is ludicrous. There's nothing in OS X (barring maybe expose) that hasn't been around for years in UNIX/Linux, so if anything they copied from Linux (or UNIX or Solaris, at the application layer it's really all the same for the most part). OS X never claimed (to my knowledge anyway) that any of its features were new or particularly innovative, but in typical fashion Apple delivered a lot of existing concepts in a very clean and consistent finished package, something Microsoft still fails to achieve with astonishing regularity. Apple has a long history of taking other peoples ideas, polishing them up, and combining them in interesting ways to make finished products that provide a very nice end user experience. Microsoft on the other hand has a long history of taking other peoples ideas, using nasty marketing tactics to drive competition out of business and to jack up the price of their offerings, and then delivering a hastily slapped together beta^h^h^h^h finished product that quite often doesn't even make it through the install process without running into problems. There's a reason the industry standard for Microsoft products is to wait to buy anything till at least service pack 1 is released.
On the topic of MS Office, all I'm going to say is that I've never seen a genuine need for anything they have to offer, as everything Office does can be done better by other tools. MS Office is the MS Paint of the working world. It's finger-painting for middle managers.
.NET is not in fact a lightweight copy of Java, I'll give you that. It's a complete heavy weight re-implementation of Java with a couple new features of questionable merit tacked on. As such, all the things that Java gets regularly bashed for are equally applicable to .NET. There is nothing in .NET that hasn't been done as good or better in other languages, so the claim that it's genuinely innovative is absurd. Actually, to be clear we really should be comparing .NET to the JVM, and C# to Java. C# brings nothing to the table that's better than Java in any meaningful way. As for the implementation of .NET and the JVM I haven't seen that either one is particularly better than the other.
If I was going to point out genuine innovation, I'd point to in no particular order: L4, Singularity (MS Research, which is not the same as MS proper), Haskell, Scala, the original inventor of multitouch (no it wasn't Apple or anyone you've likely heard of), and LLVM. This is of course by no means a complete list and new and interesting things are being created all the time, this is just what I could pull off the top of my head in short order.
As a final point, Windows success has nothing to do with standard anything, it has to do with network effect, shrewd marketing, ruthless business decisions, and some very lucky timing.
