For example, the following registry entry is omitted from the final
installation:

The changes are noted in the difference file, but they are not in the .INF
file created by SYSDIFF /inf.

RESOLUTION
==========

To resolve this problem, obtain the hotfix below, or wait for the next
service pack. Please note that you must rebuild any packages that were
built using the previous Sysdiff.exe. The latest version of Sysdiff.exe
propagates these entries and gives them the following value:

    REG_SZ:
