Regarding Registry Value

[sudheer059]

Hi All,

In Windows XP, When we

RightClick on My Computer and

select properties -> hardware ->driver signing .

there we see a check box "make this action the system default" under administrator policy .

can we check or uncheck this box using any registry value ?

If yes, what is registry value to be used ?

or

By changing any registry value can we install an unsigned driver without getting "continue anyway" message ??

Please reply to me, if u have the answer for this. I need this urgently.

This check box has no effect on my system. It reverts back to checked when you uncheck it and click OK.

Yes...

Windows Registry Editor Version 5.00

; Ignore Driver Signing
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Driver Signing]
"Policy"=hex:00

[HKEY_CURRENT_USER\Software\Microsoft\Driver Signing]
"Policy"=dword:00000000

Hi, I've tried with the registry value u have provided. But, it is not working for me.

Well according to this page you are not supposed to be able to do it. I've always just imported those values during windows setup(GuiRunOnce) and they worked. I presume after logging on it has no effect.

This one does seem to work regardless of what MS says....

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Driver Signing]
"Policy"=hex:00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup]
"PrivateHash"=hex:81,67,36,d1,1e,e5,14,21,8a,73,65,f2,1c,f9,ba,19

EDIT: I did some googling after posting this and PrivateHash may be different on your PC. It it is and the PrivateHash above does not work, then go into your Group Policy Editor as it states on the MS page and change the policy there while monitoring the PrivateHash key. See what value it gives u.
