Disable Unsigned Driver Installation Dialog Prompt in Windows XP
In Windows XP, a WHQL-signed driver installs smoothly without any warning messages. WHQL (Windows Hardware Quality Labs) secure signature (file in .CAT) is given to a device driver after developers successfully completed HCT (Hardware Compatibility Tests), and included into the downloadable driver package. The unsigned non-WHQL compliant driver, meanwhile, will pop up and prompt a warning dialog window.
The warning message basically reminds users that the hardware device driver or software that being installed has not passed Windows Logo testing to verify its compatibility with Windows XP, and users can click on Continue Anyway to force install the uncertified drivers, or STOP Installation to terminate the installation process.
It’s pretty annoying to see the warning dialog prompted every now and then, and some more it delays the completion of device driver installation, in some cases wasting time when users forget to monitor the progress and leave the installation to run on its way, stopping at unsigned driver dialog indefinitely waiting for user input.
Here’s the trick to suppress the unsigned uncertified driver warning and force installation to continue automatically.
- Right click on My Computer then select Properties to open System Properties.
- In “System Properties” dialog box, select the Hardware tab.
- Click on Driver Signing button.
- In the “Driver Signing Options” dialog box, under “What actions you want Windows to take?” section, three levels of actions on digital signature verification is provided, with default as Warn – Prompt me each time to choose an action. Default will generate the Hardware Installation or Software Installation dialog box as shown earlier whenever an unsigned driver is detected.
To suppress and skip the warning dialog and install unsigned driver automatically, select the radio button for Ignore – Install the software anyway and don’t ask for my approval.
You can also select Block – Never install unsigned driver software to NOT INSTALL any uncertified driver – no question asked, and no way to change during installation – so it’s not recommended.
- In “Administrator option” section, tick the check box for Make this action the system default.
- Click on OK button twice to exit.
Above methods works for both Windows XP Professional and Windows XP Home edition. For XP Professional, users can use group policy to enforce the no warning dialog rule too.
- Click on Start button, then click on Run.
- In the Run box, type gpedit.msc, then press Enter.
- Expand User Configuration.
- Expand Administrative Templates.
- Select System folder in the tree.
- Right click on Code signing for device drivers, and then select Properties.
- In the “Settings” tab, you should see “Enable” as the default action. Select Ignore from the drop down list to silently allow all unsigned drivers to install.
Users can also select Disable to stop all unsigned drivers installation, which cannot be overrode during installation process.
- Click on OK button.
Now you don’t have to worry about clicking on Continue Anyway when installing a new device (or old device) to let Windows use the unsigned driver.

I have this same problem witn Windows 2003 Enterprise repair of an existing windows installation. Logmein Hamachi has not passed Windows Logo testing, and this window pops up with the option to install anyway or not.
The keyboard and nouse are locked. I tried a PS2 keyboard and mouse, but it was locked too. I used Hirem”s 14.0 to rename the .inf file in Windowsinf. That didn’t work either.
Now I need to figure out another way. Registry hack, install file hack, or something else!
Needed ASAP. I am still investigating ways, but probably I need to remove the entry from the devices list. Anyone know how to do that?
Thanks for any help.
is possible to do the same thing using registry, and if so what value needs to be changed to set it to ignore?
thanks
I verified this setting to "Ingore" on XP Home installation and am still being prompted to "continue anyway"
How can i do this via the command prompt?
Very usefull!
In Windows Repair process fase 2, when installing driver I was prompted with warn dialog window, but keyboard and mice stop responding.
To avoid this problem, still working keyboard press SHIFT+F10 to open command window. Then type sysdm.cpl to open System Properties dialog window.
Use steps from 2 to 6 in this tutorial and repeat verify if option is still. For me the option selected Ignore was resets once.
Excuse my english.
when my window pops up it only says cant be installed and a ok button, i dont have the choice to continue anyway, and i did what u said to have it just not pop up and it still popped up. i have tried every way i can find on the internet and nothing works. i have windows xp professional can any one help me. and whats even weird is that just a couple days ago this didnt happen and i know i didnt change any thing.
Pasha,
I have seen the locked keyboard and mouse during setup after device enumeration and driver selection. This typically occurs when the keyboard and mouse are USB devices. I have gotten past this by connecting a ps2 mouse to allow me to click ignore on that window. A ps2 keyboard would also let you get past this issue.
Thank you this was very helpful, a much easier way to over ride the GPO for unsigned drivers.
I am getting exactly similar warning messages, but I am in the middle of the installation and my keyboard & mouse locks.
Even after restarting computer also, system will ask for Windows XP CD and start installing and will stop at some point with this message and locks my keyboard and mouse. Could someone please help.
Awesome!
I've been looking for something like this for ages. Nice, clean and simple solution without any registry hacks. Thanks!
