Not Necessary to Reinstall Windows 2000 Service Packs After System State
Changes
View products that this article applies to.
This article was previously published under Q274215
SUMMARY
After you change the system state by adding or changing additional Windows
2000 components, you do not need to reapply Windows 2000 service packs.
MORE INFORMATION
When you install a Windows 2000 service pack, the Update.exe tool performs
the following actions:
The Layout.inf file is updated with an additional source for Windows 2000
service pack files so when you add or change additional components the
Layout.inf file points to the correct source. The source location is stored
in the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\ServicePa
ckSourcePath

The source could be a network share of the Windows 2000 service pack, the
Windows 2000 service pack CD-ROM, or if you install the Windows 2000
service pack by using the Express Installation from the Web, the source is
set to the %systemroot%\servicepackfiles folder.
Windows 2000 service packs also update the Drvindex.inf file to point to an
additional .cab file for drivers that are updated in the Windows 2000
service pack. The name of this .cab file is Spn.cab (where n is the service
pack version number) and this file is installed to the %systemroot%\driver
cache\i386 folder.
A new Spn.cat file (where n is the service pack version number) is also
installed for the updated files. This replaces any previously installed
Spn.cat file that was installed with a Windows 2000 hotfix. The Spn.cat
file is installed to the
%systemroot%\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE} folder.
Hotfixes do not update the Layout.inf file. Therefore, if you install a
hotfix and system state changes occur, you may need to reapply the hotfix.
Windows 2000 service packs also perform version checking on files so that
post Windows 2000 SPn hotfixes (where n is the service pack version number)
remain in place and do not need to be reapplied after installation of the
service pack. For example, hotfixes prior to Windows 2000 Service Pack
(SP1) are updated to the service pack files.
