Yesterday during Microsoft Build 2014, they have announced Windows Server 2012 R2 Update 1 and Windows 8.1 Update 1. For those with MSDN subscription, you can download from MSDN. (as highlighted)
But how about download freely? Well, nothing is available when you click “Check Update” on Windows Update yet. Don’t worry, it will be available to public on April 8 2014. So mark your calendar and prepare to update next week.
Update 1 consisted of previous update from Microsoft. Therefore, you do not need to manual download previous update. What’s new /enhancement for Update 1 for Windows Server 2012 R2? Feel free to check out the post from here to know more.
One thing to sure that “Future updates as of the patch Tuesday in May, including security fixes, will be based on Windows Server 2012 R2 Update as the baseline”
So if you got MSDN subscription, hurry to http://msdn.microsoft.com to grab while it last (joking).
I’m downloading right now …
