ccleaner, Download it, And try to uninstall from the tools option.
If it still wont uninstall u can remove it from the list, then find the program u want and delete it from the directory manually.
After that you can scan the registry for issues, and 9 times out of 10 it will find the issues, and u can fix them.
Depending on the program they'll also be files in the hidden "appdata" folder but you shouldn't really need to worry about it.
