I log on Windows as an Administrator, and check EWF state
EWF state is "Enable"
I log on Windows as a Guest, and check EWF state
EWF state is "Disable"
EWF state is Enable in fact
I used ewfmgr.exe for the trial, ewfmgr.exe cannot read EWF state

I create an application to change EWF state. I use ewfapi.dll.
I log on Windows as an Administrator, and check EWF state. EWF state is "Enable".

How do you check that?
AFAIK, EWFMgr requires administrator proviledges. I am not sure about the API but I would expect the same.
 
We use RAM-based EWF and we show for Guest the EWF state
based on Registry information in
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EWF\P
arameters\Protected\Volume0]
value - Enabled

Best regards,

Eddy.

EWF API's require administrator or system privileges. My guess is that your application is failing to read EWF and interpreting that to mean EWF is disabled.
