No, I don't think it will help, it is too much work, and last time I updated windows I requested, I had problem with many programs, and had to reinstall.
The problem is with windows components like File Explorer, and sitting windows, the language & date in the task bar.
Resolution of the display is 2560x1440, don't know if this plays a roll.
Graphics card is nVidia p4000
I noticed that this dark rectangles disappear when resizing the explorer bigger, and return when the explorer small is.
