DUA Fails to Update System Files (Windows Embedded Standard 2009)
4/23/2012
Learn what to do when DUA fails to update system files.
Resolution
DUA does not support the deletion of system files that are currently in use by the operating system. You must rename the system file, copy over the new file, and then queue the old system file for deletion on next reboot.
For additional information, see Update System Files by Using DUA.
Example
The device update program (.dup) file includes updates to system files, but updates to the system files fail.
