I would like to start using OneGet for installing programs in windows. However, I would rather not have to go through and uninstall my current programs just so that i can use them with OneGet.
Does OneGet automatically import installed programs and if not is there any kind of tool i can use to do so?
OneGet does not support such a functionality and so the answer is you cannot do this.
