Thanks so much for responding. I can't tell you how happy I am to find this information; it's been bothering me forever that those fonts are so small. OK, I think I know what was wrong but I need to clarify this. First of all, I was looking in Shell 32.dll and then looking under MUI, which gave me that binary file. So now I've found Shell 32.dll.mui in both the System32 and SysWOW64 folders. Do I have to edit both of those or can I edit one and copy it into both folders? Just to remind you in case it matters, that I have Windows 7 not 8. I have another question: I was hoping to be able to edit to increase the size of the font in the task manager especially, but I see it is not listed among the dialogues in that file. Do you have any idea where it is?
