I would just perform Google searches for each thing you want to do. For example, if you want Windows 10 to look more like Windows 7, do a search for that ("make windows 10 look like windows 7). Downloading and using "Open Shell" (formerly Classic Shell) is the first thing you should do and should make you feel much better very quickly.
I don't know what you mean by "removing Bing". Bing is a search engine. If you don't like it, just use Google instead.
If there is anything specific with which you continue to have problems, just ask and we'll do our best to help.
