Why the Windows 8.1 Update probably means no more Service Packs for Windows

In response to customer outcry, organizations holding off on deploying the Windows 8.1 Update will be able to get security updates for their systems for another three and a half months, as opposed to the 30 days that Microsoft originally promised.

When the Windows 8.1 Update designed to improve the mouse and keyboard experience of Windows 8.1 was initially released last week, Microsoft said that it was a mandatory update. Any future security updates, starting from next month, would require the update to be installed.
