App store for Windows [duplicate]

Software store/market for Windows with freeware?

I'm wondering if there is any good App Store for Windows.
I stumbled on allmyApps, and this question, but surely there are more out there.

My dream Windows App Store would do things like:

1. Allow me to download and install software
2. Allow me to pay for apps
3. Check which apps are already registered on my machine and keep track of them
4. Keep track of all my machines
5. Keep track of available upgrades and easily deploy them.
6. Let me discover new apps that may be useful

I know this is utopian on the Windows platform since development, upgrading, purchasing are so fragmented, but the Apple Store, Chrome App store, etc do make your life easier.
Just trying to find something to ease the pain a little bit...

So, are there any good services/software out there that would help me achieve some of the listed goals?

There are 2 sites I know:

1. Intel AppUp - tries to be an app store, has all the "usual suspects" (Angry Birds, Fruit Ninja etc) and even has a developer program
2. Ninite - sorta, but not the same. Allows you to pick several freeware/shareware apps and package them into a single installer. If you run it on multiple computers, you're guaranteed the same install base. And it supports updates.

As stated, such an app store does not currently exist. HOWEVER, it is my understanding that Microsoft is working on one for the next version of Windows - there have been several leaked reports suggesting this - a simple google "Windows 8 App Store" should provide you with more info on this.

Except of the sidebar gadget download section there is no app shop for widows. There may be third party things like that, but no native Microsoft one. If you want to use third party software like allmyApps or something like it, you will be disappointed because there is no really useful software in it. Most of those third party "AppShops" only contain tiny fun application for high prices which does not make any sense. The really closest thing to an appstore for windows is the chrome app store.

Correct me if I'm wrong, but wouldn't Steam be considered "an app store for windows". Just so happens that the store only contains games...

Following this idea, Direct2Drive... Games for Windows Live... Maybe even Good old Games if you don't mind it being entirely within the web browser...

Windows Marketplace has been available since Windows 95. Until 2008 this was very similar to what we now know as an app store: 3rd parties could submit software products for inclusion in the store. Microsoft would then vet the products for quality (they had to pass Windows Logo certification) and handle the monetary transactions, just like a modern app store. Of course, back in the Windows 95 days that most often meant shipping you a boxed installation CD after purchase, but there were some downloads as well.

Unfortunately, software vendors prior to the iPhone just weren't interested in the process. By the time the app store concept was validated Windows Marketplace was a damaged brand by the time Apple proved the App Store concept workable. Microsoft is now in the process of rebuilding Windows Marketplace as the Microsoft Store, but they no longer accept 3rd party software.

There are a number of products out there that would just love to take up the slack and become the new Windows App Store. However, what makes the app stores work for Apple and Google is that they are the premier and supported way for getting apps onto those platforms. This enables the stores to simultaneously attract both customers and developer submissions. Any similar option for Windows would have to be heavily promoted by Microsoft.
