I do not think you have to go to the extreme of uninstalling all the fonts.
Have you looked in Display Poperties>Appearance and then clicked on the Advanced button
and then changed the font style and size for the Active Window? Whatever that is set to is usually what changes the default text style and size in the windows.
Using Windows System Restore to return the computer to the way it was the day before these problems started is another option if the above doesn't work and there are bound to be other options too.
I would hold off on deleting the fonts until all other options have been exhausted.
It seems like Windows must have some fonts installed or else you will run into problems before you have a chance to reinstall them.
Also, have you rebooted since this problem started?
