Is there a windows store for the desktop version of windows 10?
I did not even know that. Does it also Work with Windows 7/8?
It was released with Windows 8.
It only carries the new 'modern ui' apps. There are a variety of technologies in place to make the apps more self contained (more sandboxed); as well as let you potentially deliver the same app to Windows Desktop, tablet, and phone, (and xbox) consumers in one transaction.
Its not all bad. The original 'metro' was far too "phone/tablet" and lousy for desktop. The only one I personally use is Netflix.
Its gotten better, the apps will run in windows now ("small w" windows ie not full screen), and they added title bars and so on to the desktop version but I still have zero desire to use it for games or anything paid.
Myself, I like steam and gog. Both steam and gog are cross-platform (mac+windows+linux); which I actually value a lot vs (winphone+windesktop+xbox) which I do not value at all.
I could see the Windows store coming to replace random download sites for a lot of things, and that would be a good thing for the user experience and for safety + security. (e.g. it would be a good source for stuff like CPU-Z, qbittorrent, Acrobat Reader, Dropbox... etc etc... ) Having all that in the windows store would be good for the windows platform -- updates could be centralized instead of each doing their own.
The trouble with that is right now none of those apps will actually currently work if delivered by the windows store; due to the restrictions and sandboxing etc. CPU-Z I think needs admin rights to get the CPU information it reports, which store apps can't have. Dropbox needs shell integration which store apps cant' have. qbitttorrent... not sure if the windows store can distribute GPL stuff due to GPL license rules on making source available via the distributor...Maybe it is? And acrobat reader installs browser plugins etc which the again... app store apps can't do.
So... its a neat concept, that needs to happen but the chasm between what an app store app can do, and what windows desktop users need is still too wide.
This is why MS is focussed on games -- games are generally pretty self contained, and they are hoping to tie it together with xbox which makes sense, and may be of some value to xbox owners... to be able to play chunks of their xbox library at home or on their laptop...
The point being... a good app store run by microsoft would be good for the windows ecosystem. However, if Microsoft tries to squeeze out the other app stores, that would be a bad thing.
