Trying to figure out what programs I will use if I move from Mac to PC

I have been talking about it for ages, and have used Apple Computers since I was 7 and got an Apple IIC. I love my Mac, but it getting old, and the next macOS Sierra has end of lifed my 4,1 MacPro. Luckily I can hack it to become a 5,1 with a simple firmware hack, so I can install Sierra, but it is likely the last Mac OS my computer will run. And big Adobe updates usually require the latest Mac OS. And the new “MacPro”, the trashcan is a joke that has not been upgraded since it’s release in 2013. It isn’t upgradeable, nor can it have more than one harddrive internally, so it isn’t pro. And it’s use of a Xeon processor is not a boon. Xeon’s are usually a few generations behind on technology, the big difference is that Xeon’s don’t have an integrated graphics processor (which doesn’t affect you if you us a high end graphics card) and they 2 processors! But the trashcan can only use one! And yes it can have 12 cores (for an insane price), but i7’s have now reached 8 or 10 cores and are newer tech, so why not use those if you are only using one processor. I really don’t get it!

And yes I could build a Hackintosh, but I have been using a Quo at work,mand while it is great, upgrades are never too fun, and you must disable security features to even install El Capitan.
So it is looking like my next computer is a PC, cause I can put an NVIDIA Geforce 1080, but I need to figure out moving away from many of my current programs.
I know I can move iTunes to PC, though I hear it doesn’t work as well on the PC, but my library and ratings will make it over.
I can export and move my mailboxes, browsers and the like pretty easily. There is nothing to easily move my Photos library to Windows, but I can import my Library into Adobe Lightroom and it will take my Keywords, then move to PC so it will work there. Pages and the whole iWorks suite is a pain as I need to open each file and save it out to word (hopefully I can automate it).
Making my web sites is more of a pain. I have used many programs over time, starting with Net Objects Fusion before it went Windows only, and I have even used Dreamweaver, though my HTML skills have gone to hell, and I don’t want to code anymore. So currently I use Rapidweaver, which makes it easy and I have 2 different web sites for me and my mom’s web site, which can link to much web site content. Now I am starting to look at Adobe Muse as an alternative, but I am not sure it will easily plug into all the content I currently use, from YouTube, Vimeo, 500px, or Flickr, so sites you can easily upload things and have them automatically show up on your web site. And it looks like there is no way to embed my blogger blog into muse, as I have done with Rapidweaver. Might be able to do my self hosted wordpress, but not my blogger blogs. Damn!
Then I will of course have to figure out a bunch of other programs, and especially system tweaking, and a new backup system, as I can’t use time machine anymore.
It is surprising to me how little info there is online for moving from Mac to PC. Any info or even programs to help seem to be made to go the other way.
Oh well, when it happens I will likely be running both machines for a while, until I am sure everything is moved over.
And I am sure I will miss my Mac in many ways as I have Windows 10 in parallels and bootcamp on my mac, but it works, and honestly is a more pro system nowdays.
