reg and Machine2.reg, respectively,
as described earlier in steps 2 and 3.
What you now have is a snapshot of the entire Registry taken before and
after the change was made. It??™s important that the snapshots be taken
immediately before and after the change, so that other trivial settings,
such as changes in window positions, aren??™t included with the changes
you care about.
7. All that needs to be done now is to distill the changed information into a
useful format. Windows comes with the command-line utility File Compare
( fc.exe), which quite handily highlights the differences between the
before and after files.
There are several Windows-based third-party alternatives
that are easier to use or offer more features than fc.exe, such
as UltraEdit (available at http://www.ultraedit.com); even
Microsoft Word can do text comparisons (although you??™ll
need to remember to save the results as plain text).
Open a Command Prompt window (type cmd in the Start menu Search
box and press Enter), and then at the Command Prompt, use the cd
command (Chapter 9) to change to the directory containing the Registry
patches. For instance, if you saved them to your desktop, type:
cd %userprofile%\desktop
8. To perform the comparison, type the following two lines:
fc /u user1.reg user2.reg > user.txt
fc /u machine1.reg machine2.reg > machine.txt
At this point, the File Compare utility scans the two pairs of files and
spits out only the differences between them.
