With the Advanced System Font Changer, the system settings for text rendering in Windows OS can be changed. The software is designed to fill the gap created by Microsoft's decision to discontinue the option for setting the font sizes used by the system in Windows 10 Creator Update. Besides, according to the feedback and suggestions received since publishing the previous version of the program, the need for a version that allows more detailed settings has emerged.

With Build 1809 of Windows 10, Microsoft has introduced a system font size setting option, which made the text information displayed on the screen easier to read. The setting of other font attributes is not supported.

System Font Size Changer is a text display repair tool. It enables to change the font sizes used by the system. The program was created as a consequence of the fact that Microsoft has removed this option in the Windows 10 Creators Update version.

It is a fundamental problem of Windows operating systems that the default font sizes used by the system are quite small when using a high resolution display setting, thus making reading difficult. In previous Windows versions there was a customization option for this.

Microsoft removed the option to change Windows 10 system font settings from Build 1703. Since then, visually impaired users and those using high screen resolutions run into serious problems with the readability of the displayed text.
