Resolution & DPI

I still don't understand this dilemma. I'm working on a 22 inch monitor that has a native resolution of 1920*1080 but there are lots of elements in the Windows 7 x64 UI that is too small even for my vision which is 100% good. I also notice this tiny text phenomenon on programs like Photoshop & InDesign especially in the Preferences dialog box where the list of options in InDesign (General, Interface, UI scaling,...etc) are way too small for me to read to the point that I need the magnifier app just to read well! I thought it's a Windows 7 issue so I had to live with that but I've never seen any change in that aspect on Windows 8 and Windows 10 which I've tried only for the hope of finding a real solution to this problem but they both disappointed me so I'm back to Windows 7.

All the solutions I've read on the internet are talking about raising the DPI to 125% or even 150% but raising the DPI to e.g. 125% makes my screen's real estate even smaller thus I'm not taking full advantage of my screen/resolution so I'm really stuck between two hateful situations. Will we never have the ability to work with default 100% DPI and at the same time, those tiny text elements are taken care of to look bigger and more sharp? What's the difficulty for the programmers in having that become true?!
