when was windows 7 service pack 1 released
Windows 7 Windows 7 Service Pack 1 (SP1) was announced on March 18, 2010. A beta was released on July 12, 2010.[116][117][118] The final version was released to the public on February 22, 2011.[119] At the time of release, it was not made mandatory. It was available via Windows Update, direct download, or by ordering the Windows 7 SP1 DVD.[120] The service pack is on a much smaller scale than those released for previous versions of Windows, particularly Windows Vista.[121]
Windows Server 2012 Unlike its predecessor, Windows Server 2012 has no support for Itanium-based computers,[6] and has four editions. Various features were added or improved over Windows Server 2008 R2 (with many placing an emphasis on cloud computing), such as an updated version of Hyper-V, an IP address management role, a new version of Windows Task Manager, and ReFS, a new file system. Windows Server 2012 received generally good reviews in spite of having included the same controversial Metro-based user interface seen in Windows 8.
