Your skill at finding all the possible settings of fonts in Display Properties, changing the font size in IE and use of Tweakui for other items is what is going to help.

Windows 2000 doesn't have a System Restore feature, so your plans on such backup or the user's skills on this "Proffessional" OS are usually what saves a person from reinstall.

I wish I could sit with you and ask to click here or there, but I can't see your screen and the words to describe it are difficult because the terminology of what to call the font in some screen/tool varies. Is it taskbar or toolbar? (For example.)

What I'm writing is that you dive in and test each effect in the display properties, go get TweakUI for other effects and learn what you can do.
