How to remove installed apps from apps list without uninstalling?

often i do things for "no good reason" as well. tinkering with a pc for me is often not "do i need to?" but rather "can i make it happen?"

so i can imagine valid reasons to try to do it, however, i find it hard to believe others have the same "valid" reasons to try it that i dream up :)
 


I do as well.
But, when a person asks for something weird like this..."Why?" is the default first comment.

If it were just for my playing around and investigation, and I was at a stopping point...I'd probably give a list of things I had actually tried and failed with.
Instead of just "How do I do this weird thing?"
