This article describes how to locate core operating system software updates for Microsoft Windows CE Platform Builder products. Core operating system software updates are only supposed to be used by operating system implementers. Core operating system software updates are not intended for any one of the following:
An individual change that is made to a Windows CE Platform Builder product and then released to users of the product separate from the retail product package is referred to as an "update." A group of files for a particular update is referred to as an "update package." An update package contains several packages for the various operating system processor kernels together with an HTM file that contains the list of fixed components. The HTM file points to Microsoft Knowledge Base articles about the individual fixes that are included in the update package. These articles contain relevant technical information about the fix, including a list of the modified files.
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 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:
%windir%\system32\ceqfecheck\ceqfecheck.exeYou can use the Ceqfecheck.exe tool to determine which packages are installed. Also, you can use the Ceqfecheck.exe tool to determine whether the actual binary product files match the current update state. You must have an Internet connection to obtain the latest package information.
Find update packagesUpdate packages are available at two different Web (HTTP) update sites:
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.
