The first update, denoted as KB 955210, is said to repair a glitch that can occur when XPe's
File-Based Write Filter (FBWF) is active. "An access violation occurs during FBA.EXE due to fbwflib.dll being unloaded. We have removed the initialization and un-initialization of the worker thread, so the thread now only gets initialized if the notification API is used," Microsoft says.
The second update, KB 955222, is described as a fix to XPe's
Registry Filter, which is designed to monitor all changes to the Windows registry, and can discard them when a device is restarted. According to the company's description on its Windows Embedded Standard blog, "RegFilters DriverEntry is holding a handle on the RamDisk file, which breaks AutoChk. Regfilter does not synchronize and start monitoring keys until its user mode application calls the IOCTL [
link] via the session manager's Setup Execute Key. The fix was to have the IOCTL initialize the RamDisk rather than DriverEntry."
The third update, KB 955999, reportedly makes it possible for XPe users to add desktop shortcuts for DOS applications. A file required to enable this,
APPS.INF, was present in XPe's repository, but was not owned as a file resource by any component, according to Microsoft. "The fix was to add this file as a resource to the 'DOS Windows on Windows' component," the company says.
Further informationAccording to Microsoft, the above three updates are optional, and should be applied after the
August 2008 security updates that were announced last month.
