Microsoft has begun the roll-out of the preview versions of the coming 'Blue' versions of its core Windows and tools just ahead of its Build conference kick-off.



From All About Microsoft:

Several MSDN subscribers said on Twitter they were downloading the Windows Server 2012 R2 Datacenter preview, as well as the SQL Server 2014 Community Technology Preview (CTP) 1 bits starting around 9pm this evening (ET).

Microsoft officials disclosed at TechEd North America earlier this month that the company planned to deliver previews of the next versions of Windows Server, SQL Server, Visual Studio, and System Center around June 26. June 26 is the date when Microsoft will also be making the public preview available of its Windows 8.1 (codenamed "Blue") client.
