Perhaps, if your going for the "nobody uses it so that makes it secure" argument. Or it's corollary, "Lots of people attack Windows, that's why it has so many bugs," which is false.
There are millions of Linux web servers. Somehow they don't get compromised. That shoots down the idea that a well-used OS can't be secured. It also shoots down the idea that only Windows is used a lot.
The reality is that Windows is malware-ridden because Windows is bug-ridden. And bugs come from the factory.
And that's Microsoft's fault.
OK... so you don’t like Microsoft. Big deal.
Sure, I’ve got a bunch of linux boxes. They’re good for some things. I’ve got a bunch of Windows boxes too. And Mac boxes. Until recently I also had some VMS. Of the hundreds of servers I’m responsible for I don’t really have any chronic problems with *any* of them, or I wouldn’t have them. They do what they do and they all do it pretty well.
If it makes you happy to just simply hate Windows, well... then go for it.
Been seriously giving thought to the idea of installing Linux myself, if for no other reason than to see what all the fuss is about.
