When my setup install some Drivers the warning message "...
Has not passed Windows Logo testing to verify its compatibility with Windows XP"
appears. Is there a way to prevent it?

I don't believe so since that's by design, so the only legitimate way to prevent that is to get your driver signed by MS.

In the Windows registry you can define the reaction on installing not verified drivers:

go to
HKEY_CURRENT_USER\ Software\ Policies\ Microsoft\ Windows NT\ Driver Signing

set the REG_DWORD "BehaviorOnFailedVerify" to
0 for ignore
1 for warn the user
2 for block unsigned drivers

So maybe you just change this registry value while installing the drivers you need?

This key doesn't exist at all under windows XP!

But I found other info : M$ article

Is there any other solution???

[Perotin]

Well, on WinGuides Network you see, that the trick should work, if you add this key ...

They say it works for Win2k/XP.

Maybe you set up a test machine and give it a try ...

The other way would involve driver signing by MS!

Trust me, It doesn"t work at all. I won't test it again so if you don't trust me tests it by yourself!!! And if you say to me that this works with 50% of xp versions then where is the interst???

I've tested it on a fresh Windows XP Pro 2002. I've created exactely the same key with the same value then I reboot and it doesn't work(there is still a warning message). To be very sure I put 2 instead of 0 and the reaction was ok ->if I put 2 the warning is transformed into antother window which prevent to install the non signed driver.

Another suggestion?

Try using the GUI instead:

"Control Panel\System\Hardware\Driver Signing"

[ewwallace]

Setting the Registry key directly is not recommended, as this is a System Policy setting which should be set with either:

(1) the System Control Panel's "Driver Signing Options",
(2) the Local Security Policy Control Panel, or
(3) domain Group Policies

However, in my experience this setting doesn't really work. For a more detailed explanation with screen shots, see my post at http://www.ewall.org...yarticle93.html

So, not wanting to beat a dead horse, but my client is asking again... Anyone have any other solutions? Thanx...
