dman4x4,
Welcome to SevenForums, No It is not a stupid question. The same thing is in a few people's minds. The popular answer will be no, clean install only period. Why, because that way you will not have any old code or bits of buggy stuff in your install that may or may not be a problem for you. I intend to do a clean install for this reason. However I will be backing up my files and writing down all my tweeks so I can get my new install back to what it was. A very good OS with no problems at all for me. Hope this may have help you. lm
