Windows 10: I fixed the screen getting smaller in size but have to fix desktop now

So i had this problem where screen got small in size and i fixed it. However desktop is completely messed up. before: (a bit messy) now:

:)

 

Screen size does not fix.

Since the new upgrades the screen size is too big for my 7 YR old Toshiba Laptop, which I use constantly. I Can not access the x or the scroll bar. The character's are Hugh, stretched and distorted. I have followed every single step listed in troubleshooting
and even paid two computer techs to fix it. NOTHING WORKS! There used to be a simple one step adjustment: Settings: Display: Screen Size. Neither, Resetting, troubleshooting app, driver updates, changing to another resolution (which btw is suggested as a
fix but non existant) nothing works. I am at wits end. The last guy I paid to fix it suggested I just buy anew unit? I can't afford that. Please please address this issue asap. Thank you

Poll: Desktop Screen Size

This goes along with my Desktop Screen Res poll. A lot of people have been posting their monitor size in addition to voting in the poll, but I wanted to make an actual poll to put the screen size votes in a more easily readable format.

This is for desktop systems, not laptops. I've tried to include all screen sizes that people are likely to have; if yours is not listed, round up. If you have multiple, different-sized screens, check all that apply. I've also listed projectors as an option.

I didn't list individual sizes over 32" as these are typically not intended as PC monitors; just select "Larger."
