Yes there are significant differences between the two yet there are also
some similar or common elements. You should begin with a bit of light
reading to orient yourself around the NT registry. As a starting point
I recommend the following:
Windows NT Server Product Documentation
Appendix A - Windows NT Registryhttp://
www.microsoft.com/resources/documentation/windowsnt/4/server/p...
While some of the information about the technical limitations such as
RegistrySizeLimit are today vastly different and although some of the
tools mentioned (like Regedt32) have been replaced or incorporated into
other tools, the basic information in the above appendix is mostly all
the same or applicable to Windows XP.
Add the following to the read list and you will have a solid base of
information about the registry:
