Microsoft has revealed a little more of the Windows 8 Store experience, with screenshots and video of browsing the store, application search, and the install and upgrade experience.
The store will be the sole source for non-enterprise users to get Metro applications; it will also include links, but no purchasing or installation, to certain desktop applications. The post describes the major parts of the store—browsing, searching, the descriptions for each application—and showed how application pages will pick up their particular application's branding.
The store will handle installation and updating for Metro applications. Updates will be automatically downloaded in the background—though only when using an unmetered Internet connection—and installed on-demand.
Recognizing the growth in multi-PC households, the store also handles reacquisition of previously purchased/downloaded applications on different PCs. Apps can be installed on up to five machines, and the store can show you all the apps you've bought or installed on other systems plus allow you to install them all together on the current machine. Applications can even implement roaming, allowing not just the app itself, but also all its states and settings to be installed on a different computer.
