There should be no need to reinstall earlier Windows versions now you've had Win 10 on your PC; Win 10/MS should automatically register your installation. (either 32 bits or 64 bits- whichever).
Suggest you download latest install media for Win 10, which hopefully (assumption) includes the Nov upgrade, if you see what i mean. Do a clean install of that.
Get a copy of Aomei Backupper or Macrium Reflect (Free) and an external USB disk at least twice as large as what you're going to back up, and create its boot disk.
Enable System Restore, and install utlities to
a. implement a daily (e.g.) scheduled restore point (Brink produced one- maybe in eightforums)
b. allow you to manually create a named one (ok that's just a convenience- you can do that using Windows GUI- I just find it less hassle and quicker)
As soon as your basic installation of Win 10 with drivers is up and running, image it using one of those tools.
Now cautiously start installing your programs; keep a simple log of what you're doing (not on C:!).
Periodically make an incremental or differential image as you prefer using one of those imaging tools.
Thus you can
a. Restore your image when things go wrong in a time limited way.
b. Identify what it is that causes you a problem - it sounds like some sort of incompatibility.
Disk imaging is ESSENTIAL. Windows is flimsy and easily takes offence.
