You can solve this by modifying the registry a little bit. It's pretty easy.
- Go to registry : Start -> run -> regedit
- Go to : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts
- Right click the fonts you want to modify and type the name (the actual file name) of the font you want substituted. (For sticky notes, modify both Segoe Print and Segoe Print Bold. For example, arialn.ttf and arialnb.ttf for Arial Narrow)
Reset your computer, and you should be good to go.
