I installed Uxstyle core successfully and was able to install the theme I wanted. However, Uxstyle core does not do things such as replace navigation buttons/start button. So I downloaded another program called Theme Manager which let's you load up the files provided with the theme you downloaded and install them.
My question is whether I can use this program to install only the explorerframe.dll file? I don't want to change anything but the navigation buttons. Will this work? I am also sort of apprehensive because I have heard from numerous people that messing with those files can really wreck your system if you do something wrong. It doesn't seem complicated but I know from experience how easy it is for something to go wrong! So would I just load the explorerframe.dll file into the program and that will replace all the navigation buttons?
I also made a system repair disc just now because I heard this would come in handy if something went wrong. Is that sufficient?
