Thank you for information!
How do you make Windows continue using the driver after rebooting out of ‘disable driver signature enforcement’ mode? My computer goes right back to the “cannot verify the digital signature” error.
The setting will return to its original state after restarting.
For your information, the command to close Disable driver signature enforcement (or enable driver signature enforcement) is:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
After these 4 steps, you can use uncertified drivers on Windows 8 and 8.1 (64 bit) whenever you want.
Tips: This operation reduces the security factor of the system. Therefore, it is not recommended to close Disable driver signature enforcement all the time. Meanwhile, it is not suggested for inexperienced users to use this operation.
Nice tutorial thanks for sharing. it will help all disabled persons using windows 8. What about OS?
This will work on Windows 8 and Windows 8.1(it will look a bit different on 8.1 but similar process)
Awesome! Glad to hear it worked for you too.
Hello,
this is really good. thank for this information..
hi there, I’m trying to install a driver that will restart the pc several times. so after the first time it restart the computer the enforcement kicks back in. what can I do?
thanks for your help
What printer driver are you trying to install. There is a good chance that the Windows 8 drivers have already been released.
Will your technique work with the Dell Inspiron 15 lap top and the V715W printer dribver?
These steps are meant for our line of professional photo dye sub printers from DNP, HiTi and Mitsubishi. I can’t really say if it will work on your V715W but it’s worth a try.
I have a problem with this, when i restart to press f7, my keyboard turns of and i can’t press anything. It is a USB keyboard.
Have you tried pressing just pressing the number “7” key? Try that. Is this on a laptop?
Sometimes the top “F#” keys get locked unless you press a specific function key to enable it. All depending on the laptop’s brand.
Thx for the comment, but I have 1 question: After I select the 7th point, and the computers restart, how can i check if this setting is on or off? Because it always displays the same text: “Disable driver signiture enforcement”
Sorry but I believe there might be no way of telling if it’s on or off after you do the setup. Let mew see if I can get confirmation on this.
