Windows Server 2008 build 6003

Windows Server 2008 build 6003 is an updated version of Windows Server 2008 Service Pack 2.

It was first introduced in the KB4493471 update because the minor revision numbers are required to stay within a certain range ( inclusive, or decimal 16384-24575; the version of the kernel in the previous month's update is , where the minor revision number is  ). This build number change allows the operating system to be serviced for the remainder of its lifecycle by pushing back the revision number, whilst keeping the overall version number unique.

This update features a new version of the HAL driver which fixes the corruption bug that affects Intel CPUs based on the Haswell and later microarchitectures, present in build 6002 and older.
