NOTE: I have not yet tried this utility, I am posting this in case some have the problem of blurry fonts in win 10 Device Manager etc. with a High Resolution, wide screen monitor.

Windows 10 uses a different scaling method than Windows 8, for reasons unknown—but it seems to scale poorly in certain built-in apps, like Device Manager, Computer Management, or dialog boxes. An app called “XPExplorer - Windows 10 DPI Fix” solves this problem by reinstating the old Windows 8 method of DPI scaling.
The problem in Windows 10:
When you have a widescreen, with a resolution of 1920x1080 or higher or a bit lower, in Windows Vista, 7, 8 and 8.1 you would put your DPI scaling to 125% or higher to make text and images appear larger and more easy to read.
But when you put the DPI scaling to 125% in Windows 10, you see in a lot of dialogs and windows the font gets very blurry.
It does not matter if you are using the regular or custom Windows DPI scaling functions at your 'Screen properties'. Text will get blurry on 125%.
You can test if you have this bug also if you put your DPI scaling to 125% at your 'Screen properties', then reboot Windows (or sign in again when it asks you).
Then goto 'Control panel > Administrative tools > Services'.
If you have this issue also you would see the titlebar of the Services window has a font scaled good. But the services list itself is very blurry/unsharp to read.
