That is because the IconFactory made them.
I see what you mean... followed the link and thought....who in their right mind would pay for such rubbish? Certainly not I.
To say that the direction icons have been going recently is somewhat disappointing is a complete understatement, to say the least.
Yes, by all means make an OS as efficient as it can be for those who want ultimate speed and performance, but don't sacrifice appearance to achieve it and bring back Aero. It may have used some resources, but it needn't be activated by default, just make it an option for those who DO want it.to escape this crazy 'flat phase' the movers and shakers of PC world seem to be going through.
It's a bit like condoms, really... one size does NOT fit all... nor do 'flat' GUIs appeal to everyone. So okay, Microsoft, leave the prettying up of OSes to companies like Stardock, but at least give them an acceptable appearance for those who do not customise their desktops. Oh, and thank goodness for Stardock providing us the tools to vastly improve upon that which is sup-par in Windows, aesthetically speaking, that is. I love Win 8.1 in its customised state, it is fast, efficient and stable, but the default GUI is crap,
So there you have it, Microsoft... and please learn from this thread/your mistakes.
