Microsoft App Updates
When Microsoft decided to make apps available through the Windows Store as part of Windows 8, we thought long and hard about the implications for our security update policy. We knew app updates would have to differ from traditional security updates (delivered on the second Tuesday of each month and often the primary or only updates made to a program).
The Windows Store introduces a model in which regular updates are a normal part of using software. Apps are updated frequently to add new functionality, fix bugs, and improve security. Improved Application Programming Interface (API) and security models help developers avoid introducing new bugs in updates. The operative expectation: quick and painless updates.
How the app update policy has changed
Our security update policy has been adapted to align with the new model. It will apply to Microsoft apps that are installed using the Windows Store and to apps like Mail (preinstalled with Windows 8 but updated using the Windows Store). The policy changes are outlined as follows:
What this policy means for monthly security updates
The policy changes described here do not change the way we update traditional software such as Windows itself, for which updates will continue to be released on the second Tuesday of the month with an accompanying security bulletin or in out-of-band updates when circumstances dictate.
Microsoft is committed to preserving the attributes valued in our traditional update policy while adapting security update releases to meet broader customer expectations around apps available through the Windows Store.
