The simplest way is you type something in Word Pad, change text into the font you want, and then paste that text into Sticky notes. However, I don’t want to carry out copy-paste task all the time. I want to reset the default font for Sticky Notes.
I replace all the “Segoe Print” in StikyNot.exe.mui with Arial font. (StikyNot.exe.mui is placed in folder “C:\Windows\System32\en-US\StikyNot.exe.mui”). By changing the *.mui file, we can make sure that Sticky Notes now use Arial as the default font instead of Segoe Print.
