I've been making a thesis for vb6 but all I can do is search all the registry keys and don't know if it's bad or good. can anyone please help me. I know that installers nowadays delete those registry keys if they are uninstalled. maybe my thesis is nonsense but then please help me. :(

What is the thesis?
What are you searching for (both 'why are you searching' and 'what do you hope to find')?

deleting unwanted registry keys and backing them up. it's like a registry cleaner.
