Windows 7 - Service Pack 1

Service Pack 1

Windows 7 Service Pack 1 (SP1) was announced on March 18, 2010. A beta was released on July 12, 2010. The final version was released to the public on February 9, 2011. At the time of release, it was not made mandatory. Technet has information on blocking it, or getting it via Windows Update, direct download, or by ordering the Windows 7 SP1 DVD. Microsoft confirmed that the service pack is to be on a much smaller scale than those released for previous versions of Windows, particularly Windows Vista.

Windows 7 Service Pack 1 adds support for Advanced Vector Extensions (AVX), a 256-bit instruction set extension for processors, and improves IKEv2 by adding additional identification fields such as E-mail ID to it. In addition, it adds support for Advanced Format 512e as well as additional Identity Federation Services. Windows 7 Service Pack 1 also resolves a bug related to HDMI audio and another related to printing XPS documents.

Some programs have compatibility issues with SP1 and a limited number of programs may experience a loss of functionality.

Famous quotes containing the words service and/or pack:

    A man’s real faith is never contained in his creed, nor is his creed an article of his faith. The last is never adopted. This it is that permits him to smile ever, and to live even as bravely as he does. And yet he clings anxiously to his creed, as to a straw, thinking that that does him good service because his sheet anchor does not drag.
    Henry David Thoreau (1817–1862)

    Madame Sosostris, famous clairvoyante,
    Had a bad cold, nevertheless
    Is known to be the wisest woman in Europe,
    With a wicked pack of cards.
    —T.S. (Thomas Stearns)
