An update is always developed by using the most recent source code for a single product. The update is only tested in a specified configuration. Therefore, an update is only supported when it is installed on a specific product version with all previously issued update packages already installed. Therefore, you must install the previous yearly updates and all the monthly updates before you install the update that you want.
Understand update typesAn update may be found in one of the following update types:
- The version, followed by a hyphen
- A numeric date tag, in year month day format (yymmdd)
- A tag that specifies the Microsoft Knowledge Base article number, followed by a hyphen
- The processor type
The yearly update is a package that contains all monthly updates that are available at the time of release. Each package is provided separately for each processor kernel that is available in the target product. This is true except when a particular change does not apply to a particular processor kernel. Then, no package is required.
When a yearly update package is released, the monthly update packages are removed from the update site. The yearly update package can be quite large.
Determine fixes that are requiredThe installation packages are designed to install their components only if the components are newer than the components that are currently installed in the build environment. To most easily bring your system up-to-date, install all the currently available update packages. The build environment requires the installation of the following:
- The yearly update package
- All monthly update packages that are released after the yearly update package
Find update packagesUpdate packages are available at two different Web (HTTP) update sites:
- Microsoft Developer Network (MSDN) downloads
The MSDN Web site contains all the update packages for each version on an easy to read page. For more information, visit the following MSDN Web site:
- Microsoft Download Center
This Web site contains all the update packages. For more information, visit the following Microsoft Web site:
- Specify the following search words:<version> Builder UpdateNote The placeholder <version> is the operating system version number, for example 5.0, or 4.0 for Windows CE .NET.
- After the search is complete, set the Sort Results By: field to Release Date.
Understand the availability of update packages and Microsoft Knowledge Base articlesUpdate packages and Microsoft Knowledge Base articles are published to the Web by using separate publishing systems. If the Microsoft Web site is missing either the Microsoft Knowledge Base article or the corresponding update package, you may find that the missing publication is available in a few days. If you have to have the Microsoft Knowledge Base article or the corresponding update package immediately, telephone Microsoft Product Support Services.
Each update package also has associated Readme files. You can view the Readme files after you install the update package to the operating system base directory of the build environment. The Readme files give a list of individual changes that are included in the update. The Readme files will associate the individual change with the related Microsoft Knowledge Base article.
