Here is a handy utility you can use to correct the problem called XPExplorer – Windows 10 DPI Fix, and it’s free.
Start it up and check the Use Windows 8.1 DPI Scaling option and then choose your scaling level.
A restart is required to complete the installation. When you get back fonts in the apps you were having issues with, they should no longer be fuzzy, but clean and clear again.
This utility is nice to have because it will work across the board and you won’t need to use the manual method for fixing everything that has fuzzy/blurry text.
