I have searched the internet and this forum and I can't find what I am looking for. I have already changed the system font is the registry to Black Chancery but I can't figure out how to change the size of it. The key that I used to change the font is "MS shell DLG" under font substitutes. But I'm not sure what to change for the size and at the regular size it is so small you really can't see it. It is possible to change the default size?

Hi Chuck. I already know how to do all of those things with the desktop properties. I'm trying to change fonts in things like the task manager, start button and clock and even the download box. I have been able to change the font itself but it is way too small and I can't figure out how to change it. Have any other suggestions??

In order to change the fonts you want you can do a couple of things. In Display Properties you can change your font DPI to 'Large Fonts'. This will increase ALL font sizes. If you are using visual styles you can change whatever style you are using to make the fonts bigger. Using the normal method in Display Properties does not change all the fonts like the ones on the Start Menu. You need a visual style editor or do it yourself with a program like ResEdit. You have to know what you are doing.
