Καλησπερα,

Μια απορια εχω στο University of Patras - APPSCI - MSDNAA | Academic Software Discounts msdn εχει δυο εκδοσεις windows την κλασσικη και την Microsoft Windows 7 with Service Pack 1 Debug/Checked Build Ποια ειναι η καλυτερη;

[MUL]

Αυτη με Service Pack 1 ,βέβαια και η απλή έκδοση θα κατεβάσει το Service Pack 1 μολις την εγκατστήσεις

Two distinct builds of the NT-based operating systems are available:

The free build (or retail build)

The free build of Microsoft Windows is used in production environments. The free build of the operating system is built with full compiler optimizations. When the free build discovers correctable problems, it continues to run.

Distribution media containing the free build of the operating system do not have any special labels — in other words, the CD containing the free build will just be labeled with the Windows version name, and no reference to the type of build.

The checked build (or debug build)

The purpose of the checked build of Microsoft Windows is to make identifying and diagnosing operating-system-level problems easier. The checked build differs from the free build in the following ways:

• Many compiler optimizations (such as stack frame elimination) are disabled in the checked build. Disabling such optimizations makes it easier to understand disassembled machine instructions, and therefore it is easier to trace the cause of problems in system software.

• The checked build enables a large number of debugging checks in the operating system code and system-provided drivers. This helps the checked build identify internal inconsistencies and problems as soon as they occur.

Distribution media containing the checked build are clearly labeled "Debug/Checked Build." The checked build distribution medium contains the checked version of the operating system, plus checked versions of HALs, drivers, file systems, and even many user-mode components.

Because the checked build contains fewer optimizations and more debugging checks than the free build, the checked build is both larger in size and slower to execute than the free build. As a result, the free build is used in production environments unless it is necessary to use the checked build to identify serious problems.
