So basically you have some minor driver issues and blame Microsoft instead of doing any kind of root-cause analysis. Like how one of the most common reasons for problems like yours is malware infestation. If you've been a long-time Mac user, you may well have developed some bad habits that will land you in some trouble on Windows.
I personally went kind of the opposite direction. After using Linux for several years I gradually had less and less time to deal with all the upkeep required on Linux, so moved to Windows. Then started using OS X between 10.3-10.7, but 10.7 was a huge turnoff for me. Up to that point, each version of OS X was better than the last, but 10.7 was just a shameless iOS-ification of Mac OS X. They inverted mouse settings on everyone and you could only change them back via the GUI if you had an Apple branded mouse, made the interface look like crap on toast and unlike previous versions of OS X, there were no significant technical improvements worth the bother. About the only good thing they did was drop OS X Server as a $500/seat product and turn it into a small add-on package, which is all it ever really was.
I also had a job where I dealt with mid-level Apple managers on a pretty regular basis and just got so sick and tired of the arrogance and holier-than-thou attitude that is beaten into everyone who works there. Not to mention you can't get a straight answer out of them on anything. I worked as a repair tech for Apple stuff and they literally complained because I went an extra step and made use of their own team of techs to double check some of my diagnoses, claiming I was using the resource they advocate using in their own certification training material and all over their GSX website, too much. When I asked them to give me a specific number for how much is too much... Silence. A lot of times I went the extra mile to get Apple's people to verify that some unit had liquid damage or what not and the middle manager flunky I dealt with actually agreed it was a good idea.
That's not even getting into how it's part of their business model to basically beat up on "partner" companies. They will pick some aspect of your business and continually brow beat you over how you need to improve on that. Nothing will ever be good enough either, because the point is to have you constantly chasing your tail. You'll turn your entire business upside down and once you reach the 51% point, that's when Apple will suddenly decide they don't care about that anymore, they want you to focus on something else instead. Rinse and repeat ad nauseum. The whole thing is designed to give their own stores an unfair advantage. Any AASP that might pose even the slightest bit of competition to an Apple Store is subject to this treatment. If you're a company wanting to service your own units, they don't give two craps about you and you'll have a hard time getting your service rep to even answer an email. Same as if you're 100 miles from the nearest Apple store. But if you might pose even the smallest hint of competition to an Apple Store they will land on you with everything they've got and threaten to rip up your AASP contract at every single turn if you don't do what they say. They will be verbally abusive in conference calls or in-person meetings and assuming you manage to get a word in edgewise, if you try and push back against some unreasonable demand, they'll just increase their demands.
As I said, the whole thing is aimed at giving their retail stores an unfair advantage, which is a rather blatant violation of anti-trust laws. If you have your own retail stores, you cannot show favoritism, that's the gist of the law. But they do it anyway. They do everything they can to make it as difficult as possible for any AASP that might compete with an Apple store to actually fix customer units. In addition to everything else I've outlined, they also tend to restrict access to a lot of parts needed to fix units. Like when they redesigned the MBAir to the wedge shape, very early on it became clear there was a serious defect in the logic board. Specifically with the GPU didn't seem to be properly soldered and would cause a pre-POST boot failure. Within about a month of the product being on the market, no independent AASP could get access to those motherboards. It took them like 3 generations to finally knock that problem out IIRC. So you, as an independent AASP have to send a customer's unit in to this repair depot, meaning you don't get any money for fixing it short of charging the customer above and beyond what they would pay at an Apple store or peddling some other crap on them, but you still get to take the blame if Flextronics (who runs Apple's mail-in repair business) botches the job. It's a ding on your "Service Excellence" score, which determines how much Apple pays you for warranty repairs the following month. I remember quite vividly one time getting one of those Air units back, taking the bottom cover off to look at it, and seeing how the Flextronics tech had apparently gotten some thermal paste on their hand and just decided to wipe it off all over the battery and everything else in sight. They also stripped out virtually every screw on the thing. There was no way in good conscience I could give that back to the customer, so I had to argue for an exemption on the total repair turnaround time metric so I could have Apple ship me some replacement screws.
Apple is a monopolistic company that is very reminiscent of Microsoft in the 90s and early 2000s. They just absolutely thumb their nose at the law and even more than that, they are clearly out of ideas. The infamous deep product development well has run dry and now all Apple is doing is aping what Android device makers have been doing for years now: Getting into the phablet business. There hasn't been anything of particular note to come out of that company since Steve Jobs kicked it. They had to photoshop out the camera bulge on the promo shots of the iPhone 6. The Mac Pro that probably gets confused as a trashcan quite often, and is just a repeat of the Cube, the iMac is slowly morphing into a giant iPad, pretty soon I'm guessing the MacBook Pro line will be retired and all there will be is the Air, which is basically little more than an iPad with its own keyboard. Now the iPhone is slowly growing in size and will probably slowly merge with the iPod and iPad Air. You'll have one model with cellular antennas and one with only wifi.
I for one, will avoid using their crap as much as I possibly can going forward and will not be sad to see them go when probably by the end of the next decade they will be back in the position of having only enough cash on hand to keep going for another couple of weeks and either someone buys them up outright or they get parceled out at the liquidation sale.
