In April, we released a bigger, more comprehensive package of improvements to Windows 8.1
called the Windows 8.1 Update. We did the same for Server too, with
Windows Server 2012 R2 Update. As we said at the time, our goal is to continue to deliver improvements to Windows through regular updates in order to respond more quickly to customer and partner feedback. After all, we already have a regular monthly update process that includes security and non-security updates.
With the above in mind, rather than waiting for months and bundling together a bunch of improvements into a larger update as we did for the Windows 8.1 Update, customers can expect that we’ll use our already existing monthly update process to deliver more frequent improvements along with the security updates normally provided as part of “Update Tuesday.” So despite rumors and speculation, we are not planning to deliver a Windows 8.1 “Update 2.”
