In Creator Update build, ability to change system fonts was removed from desktops settings. One possible solution was Winaero tweaking utility, now Wintools released another utility, called System Font Size Changer which is small and portable.

Have to give credits for the news to Ghacks.net, posting here, because I saw a lot of questions about it.

Picture is self explanatory enough. All the fonts settings are there, so if you don't need all extra tweaking capabilities of WinAero, try this.
