Customize the Windows interface extensively, with Classic Color Panel
Classic Color Panel is a free, portable and powerful utility that lets you customize colors and fonts in a lot of elements, such as buttons, borders, windows, controls…
If you prefer a more detailed customization than what Windows allows, here is Classic Color Panel to help. Just don’t neglect to backup your current configuration with this same utility, in case you’d like some time to revert your changes.
The program’s interface seems a little overwhelming with all those options, but it’s easy to use and you don’t have to change everything, you can just customize what is most important for you, even try your settings for a while and keep on customizing more elements if you like.
Again, after you finish your customization use the program to export a registry file to backup your settings and restore them whenever you need to.
