Dear All,

1. In a VC MFC application we are using WMI class 'Win32_ComputerSystem' to
get the Administrative Password status ('AdminPasswordStatus' property),
Power On Password status ('PowerOnPasswordStatus' property) and Keyboard
Password status
('KeyboardPasswordStatus' property).
However when we retrieve password status using this class, results are not
consistent. It is not guaranteed that when password is enabled the password
status shall be returned as 'Enable'. Sometimes 'Unknown', 'Not Supported'
shall be returned as password status.

Could any one have idea behind this this behavior.

2. Is there any way available like WMI, Win32 API, etc. to retrieve HDD
password status that is 'Enable' / 'Disable'.
Please let me know the if any of such method is available.

3. Is it possible that some BIOS might treat Administrative Password
(privilege for doing BIOS settings) as Power On password. And when Power On
password is enabled, value of 'AdminPasswordStatus' property from WMI
'Win32_ComputerSystem' will change
Could any one plaese confirm this behavior.

Any hints on above issues are really helpful.


I had not known it was possible for Windows to query these bios level things. MS has been pushing the BIOS makers to give more control to Windows, but am not sure how much it now has, and of course older BIOS's are not compatible. Perhaps you should google "windows bios" or something and find a more appropriate document or forum. Sorry!
