Fonts extremely small in some applications - Windows 10

The title bar, menu bar and some fonts applications (such as Quickbooks, Microsoft Onedrive) get so small that the words get cut off vertically and very difficult to read.

I searched online and tried using a regedit hack to change the size, and also altering the Advanced Display Setting in control panel but none of them worked.

Any idea why this is happening? How can I correct the size, along with the containers around the small titlebar/menubar text?

One possible reason is because you're using a high DPI screen.

When programs run, Windows says "hey, are you high DPI aware?". If a program says "no", then Windows handles the scaling to ensure that they aren't microscopic. If a program says "yes", then Windows lets the program do the scaling.

Unfortunately a number of programs incorrectly say "yes" (when they actually mean "no") and, as a result, end up being displayed extremely small.

Previously you needed to change a registry setting and use manifest files to resolve this - however in the latest version of Windows you can now right click on the executable, select properties and override the DPI setting:

The options are:

• Application - The default setting, scale only if a program reports itself as not high DPI aware.
• System - Windows will stretch the UI, this will cause all text and graphics to become blurry.
• System (enhanced) - Only works with certain (GDI) programs but will scale programs whilst reducing the amount of blurring.

My recommendation would be to always try "System (enhanced)" first and fall back to "System" if that doesn't work.

On another question, i found a probably useful answer. It shows two different methods to change font sizes. Please give feedback if one of these worked for you.
