Windows Phone 8 (codenamed Apollo) is a version of the Windows Phone mobile operating system. This is the first version based off of the Windows NT kernel instead of Windows CE, being developed as a version of Windows 8 in concurrency with it.
Windows Phone has its own versioning system. The build of Windows NT that a given build is based on is stated in the build's page.
Windows Phone 8 updates are distributed via Windows Update as CABs with three different extensions: a file of type .spkg
is a full package, a file of type .spku
is an update package containing PA30
delta compressed files that can be applied on top of a previous build,[a] and a file of type .spkr
is a removal package.
