Hi I can tell you what I found in the few minutes I used OS X (I'm thinking about buying mac), I guess I could find more with more time.
1. The whole, maximice, minimice, multitask window it's much better optimiced and it's easier to do on Windows.
2. Yo got right click create document, shortcut, word, txt, etc... vs only folder on mac.
3. Deleting documents it as easier as click "delete" no need to FN combos like mac. Also this will force you to remap keys if you are using windows software on your mac.
4. Cortana vs Spotlight. Again i can just tell cortana to search some files or instance presh only one button to open it a start writing vs FN combo on mac.
5. Like it or not, believe it or not, there are mac virus, and worst, it appears to be one of the less secure systems.

Due to my studies, in my classroom there were a lot of Macs, not only find they break too at the end of the last year a few colleagues ask me to take a look at their macs because they were slow, some of them installed antivirus and find several infections. So this no virus is pure myth. Also never had a virus on W10 as long as you don't go to weird webpages or know where to download things.
6. Didn't find anything to show recent files used in APPs, but I think that was my fault.
Edit. of course: 7. Less software compatibility. Allmost all of my colleagues emulated Windows to run software like autocad, and at the end that choice gives them worst performance than just runing the software on a Windows laptop.
// On the other hand I find things better in Mac too, like the multiple-desktop and gestoures trakpad. But I think it will eventually come to windows in future updates.
I wouldn't say "less functional" at the end you do the same more or lees, but for me "less practical" and not so well polished as iOS.
1. I can agree that maximizing is more consistent in Windows. In OS X double-clicking on the title bar (or alt/option-clicking the + button, depending on how things are set up)
does zoom the window to the entire screen
most of the time in most apps, but not always. Sometimes it ”zooms to fit” like in Safari and Finder. This doesn't always work consistently depending on what is viewed within the window, so I think I agree Windows handles this a bit better. That being said, I rarely see the need to zoom a window to fit the entire screen. For most Windows users, this is often first thing they do when they open up an app – double click to mazimize. Why? There's most often not a point in running a web browser maximised on a widescreen display you will just get blank sides with no content.
2. I think you have to let go of some Windows way of doing things. You can't expect everything to work exatcly as in Windows. Since that function isn't in OS X I have never missed it.

I mean why not create the document from within the app? Is it that big of a deal?
3. Deleting items in the Finder using ”cmd backspace” is nothing strange once you're used to it. I think it's quite good a thing like that isn't very easy to do so it doesn't happen accidentally. But
I do agree that it would be nice if pressing ”delete” in the Finder while having items selected gave dialog ”Are you sure you want to move the selected items to the Trash?”, just like it behaves in Windows. Still, not a major thing I think.
4.
This will come in the next major OS X version it seems, but I think Spotlight works better than search does in Windows 10 (I guess that's the Windows version we're comparing to here?). I also really like that I can look up words in the built in dictionary from Spotlight.
5.
I remember that report. I think it's unfair. Why is it showing all Windows version separately, but OS X and iOS lumped together?
A good comment:
”Article is very biased and misleading, i mean, having iOS in comparison but not Android nor Windows Phone os, and putting Windows by versions but Linux as grouped. That’s some really bad journalism, together with all news portals that shared this article. It says P.R. all over it. Sad to see that it’s getting harder and harder to get proper information on internet, and knowing web space is polluted with misleading and bad informations such as this article.”
It's a myth that there is no
malware for OS X (does anyone think that?) but no myth that there's
no viruses. There are different kind of classifications for malware, and the ones known that exists for OS X doesn't count as viruses (as far as I know). I can tell you that at the office where I worked as an IT support guy for almost 10 years there's never been any continuously running antivirus software running on the about 100 Macs that has been in use and I can count on my five fingers how many times there has been problems with malware on the Macs. One example was two users that managed to get trojan called Mac Defender, which took me about one minute to manually remove on each computer after reading online how to do it. Good luck doing that on a Windows computer. So… while there are security concerns being an OS X user I'd say there's (still, after all these years) much less problems for the end user when it comes to this compared to being Windows user.
To finish, some good things I like in OS X that I can't find in Windows (let me know if I'm just being ignorant):
-The ability to colour tag files in the Finder
-The ability to search after a menu item in an app using the Help menu's Search filed.
-Being able to press Space to preview many files and items (Quick Look).
-Being able to calculate folder sizes of all folders in one window in the Finder and sort them after size in list view.
-Just seeing the running apps when using ”cmd tab” makes it easier to find the app I want when I have many apps (and open windows) running. Can be quite messy in Windows when a lot is open. But I do like what they've done with ”alt tab” and ”Task Overview” in Windows 10. Still prefer OS X when it comes to this.
-Ability to add or edit the keyboard shortcut for any meny item (System Preferences > Keyboard > Shortcuts).
-Preferences are in almost all apps found in the app menu (shortcut ”cmd ,”). Not so in Windows, where it can be in different named menus, and called ”Tools” or ”Settings” or ”Preferences” etc. More inconsistent.
-The ability to drag an item or a folder from the Finder to an Open/Save dialog in an app to make the dialog go to that location (try it and you'll see what I mean).
-Drag and drop seems to work in more places…
…and so on.
Edit:
One really awesome thing I found out the other day was how quick it can be to restore a disk image (clone) created from a clean install of OS X despite the size of a newly installed OS X ”El Capitan” 10.11.3 being more than 9 GB in size it can be restored to an empty and formated drive
in about three minutes, and this is even without involving SSDs. This is because ”sectors” is copied (using something called ASR – Apple Software Restore) and not the actual files.
More about that here:
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man8/asr.8.html
Can that be done in Windows? All images restoring I've seen in Windows takes ages. But maybe there's some quick way I don't know if? Which reminds me of that it takes
ages to do Windows Updates in Windows 7 (which is still used at work). Good this is improved in Windows 8/10.
