There was also a number of separate security patches on Vista which caused the command to not work. It is believed this command was rendered useless with the release of Vista 圆4 SP1 and definitely doesn’t work on Windows 7 or 8. Into command prompt will do the job, but it doesn’t work on Windows 7 圆4. There are some tutorials suggesting that typing this command:īcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS
#WINDOWS 7 DIGITAL DRIVER SIGNING DISABLE DRIVERS#
Fortunately, there are ways to force the unsigned drivers to load in 64-bit (圆4) versions of Windows 7, 8 and Vista.
It appears the obtaining a certificate to perform driver signing costs hundreds of dollars per year and not every software developer can afford that kind of money especially when their software is freeware or open source. We know that PeerGuardian has been superseded by a program called PeerBlock which doesn’t have these issues, but it’s just being used as an example to demonstrate the problem. This becomes a problem when using some legitimate software and you’re unable to load an older program such as PeerGuardian with the error message “Windows cannot verify the digital signature for this file” because of an unsigned driver. It is also very difficult for software that belongs to a high risk category to obtain a digital certificate and one example is the Elite Keylogger where it took them years to get their driver signed. This is by design to provide a more restrictive environment to protect Windows from easily being infected by rootkits, a type of malware that uses a driver for low level hooking. One of the common problems that people face when using a 64-bit Windows is loading unsigned drivers.
