I am in need to frequently use remote desktop sessions, and I was struggling to increase the font size.
I finally I discovered an easy way to complete the task.
- open the Settings window (by pressing <windows_key> + I)
- type the following string in the search bar:
make text size bigger
- click the suggested topic
The program will take you into the Display Settings page with a new unlocked option to tune the text size by a sliding bar.
NOTE: This string seems to work fine also for OS with different languages installed (Italian, …).
