Microsoft has announced that its Windows 8 Metro applications will
only be available from their own Windows Store, the official name given
to Microsoft’s apps store.
Following in Apple’s footsteps and taking full control over what will
an won’t be sold in their store. Microsoft director Ted Dworkin
explained that the Windows Store will be used to restrict Metro app
distribution to ensure the software applications are secure and
Microsoft also explained to developers that "We will examine
every application that will be submitted to us [and] we will run a virus
check and a malware check on every application,”.
Which will hopefully stop the Windows Store being plagued by
malicious applications laced with code and viruses which has happened
in the Google Market leading to applications having to be pulled. Unlike
Apple and now Microsoft Google allows its Android applications to be
purchased from other websites and sources.
Similar to Apple Microsoft will take a 30% cut in applications uploaded to the Windows Store. "Following
industry norms, developers pay a nominal yearly fee to upload apps to
the Store, and receive 70% of the gross income from those apps (for paid
apps and in-app purchases that use the default commerce engine),”
