Using App Store From Windows PC

Is anyone else searching for an answer as to whether you can use the app store on a windows computer? The answer is not here that's for sure. After googling for about an hour and reading multiple different blogs, I found out that you can only use the Apple app store from an Apple computer, i.e. MAC. I don't understand why though ?? The only advise I got from Apple Support was to click here and click here to view my purchase history. I know how to do that already and that's not what I'm looking for. I really just want to be apple to see a list of all apps I've purchased or downloaded. I would also like to be able to manage the apps as in delete, update, etc.
