we use UWF in one of our cumster's systems (Windows 10 IoT Enterprise 2019 LTSC), and told them that they may use Sean Liming's "UWFUtility" to configure UWF since Windows 10 does not provide the nice GUI tools known from Windows Embedded Standard 7 or the MMC-Plugin from Windows 8.1 "Embedded".
After some months of operation our customer claims that the "UWFUtility terminates with an execption" immediately when started. Analysis has shown that:
As per stack trace from event viewer, it seems that the tools seems to attempt some kind of enumeration
Checking the WMI Provider shows that there is no instance for the "UWF_Filter" class any more (compared against a new system where UWF works)
Even the uwfmgr utility reject command like "uwfmgr get-config" with error "Access denied"
My assumption is that the UWF configuration has became damaged in some way. It is known that the customer does not shutdown the system before power interruption. Use of UWF - among others - is based on the supposition that it should protect the file system even in case of unexpected power losses. Now I have some doubts if this is really true...
Are there any known issues regarding UWF and unexpected power losses? Or do you have any ideas how the UWF configuration may became damaged, or what else could happen that UWF does not work any more?
Have much thanks in advance.
Yours Willi K.
