Oh, I am sorry. Yes, you are right. The file "Windows XP No SSE2 Patch Rollup.zip" is in the directory "POSReady 2009" of the Windows XP post SP3 update pack.

The analysis of the newest version (5.1.2600.7334) of the file "win32k.sys" from the Windows XP update is now complete. The file "code.htm" has been updated. There are no big surprises in this version. It's basicly just another buggy version which needs to be fixed. The code is more or less the same as in Windows 2000 or any other Windows version.

---

A bug has been found in the version "5.00.2196.0001-V3" of the file "win32k.sys" for Windows 2000. That is why the version "5.00.2196.0001-V4" has been added to the file "code.htm". Even though only a single machine instruction has been changed, it will still go through some testing before the update "WINDOWS2000-OTSKB000001-V4-X86-INTL.exe" will be released to the general public. However, the help file has already been updated.

    This update is for Windows XP (32 bits) users. However, in theory it can also be used by Windows Embedded for Point of Service (32 bits) users. However, it was tested on Windows XP (32 bits). No tests have been done on Windows Embedded for Point of Service (32 bits). Also, this update announces itself as a Windows XP update in the title bar during the installation and deinstallation and in control panel -> software.

    I know, this is not perfect, but it's the best I have so far.

    Edit: see next post

    The tests on a Windows Embedded for Point of Service (32 bits) machine are complete and have shown, that the Windows XP (32 bits) update can not be used in Windows Embedded for Point of Service (32 bits). So there is a separate update available, now.

    The update "WINDOWSXP-OTSKB000001-V2-X86-EMBEDDED-INTL.exe" has been released to the general public. The help file "OTSKB.chm" has been updated accordingly. The code comparison file "code.htm" has not been changed.
