Install Windows XP Embedded with Service Pack 1 Q: I already have SP1 tools and database installed.Should I install the SP2 tools and database on top of my old SP1 database, or should I set up SP2 on a separate computer?A: You are generally advised to keep your old SP1 system operational until you are no longer servicing SP1-based embedded devices.
The following procedures explain how to cleanly install Windows XP Embedded with Service Pack 2.
Skip the first procedure if your system already has SP1 installed.
If you have a configuration in a deployed device that requires a hotfix, you usually add the hotfix component to your Component Database, open your configuration using Target Designer, and then update only the one specific component.
Note SP1 QFEs and updates will be replaced with SP2 level components.
Note For every rule, there is usually at least one exception.
For example, private hotfixes are component fixes that are not generally released to the public, but are used to solve specific customer problems.
Q: What happens if I install SP2 updates into an SP1 database?
A: This is not recommended, as it is an untested scenario.
The key behaviors are as follows: If you keep the components in your configuration version coherent, you reduce the chance of cross-revision component incompatibility.
For this reason, any time you update your run-time image, you should always update the entire configuration, following the previous steps.
Note If you are currently servicing any run-time images that continue to use SP1 or earlier, do not update your existing SP1 database.
