The steady (RC) version of it Unofficial Service Pack 4 of Windows XP is now available. Contains new improvements better safetyand stability and shows increased performance. This version will become final if the testing of the users who download it does not show any problems.
SP4 RC contains all updates for Windows XP up to May 2014 (IE8, WMP11, MCE2005 with Update Rollup 2, MSN Explorer 10.5), .NET Frameworks 1.0, 1.1, 3.5, 4.0 (the latter is not installed by default), XPS Viewer EP, MSXML4.0, Windows Search 4.0 (disabled by default), Bitlocker Go Reader and Windows Powershell 2.0 (disabled by default) while removing Windows Messenger.
Also included are security improvements against DLL injection (using references to the full path in the register, so that it is clear which files are being referenced each time) and fewer catalogs are used – which increases performance.
Some Customizations have also been made that automatically solve some problems in special KB articles – for example on Windows Firewall – and digitally signed patched files that allow XP to run on more than 4GB of RAM (these files are available separately and must be used with SP4).
With regard to Beta 3, the new version is clearly improved, since it supports all planned installation scenarios and solves many glitches.
