Some modified drivers lack a valid driver signature and this prevents them from being installed on a 64-bit Windows OS. To bypass this restriction and be able to install those drivers you need to run Windows in Test Mode or boot Windows with "Disable driver signature enforcement" option. These methods are only needed for x64 versions of Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10, Windows Server 2008, Windows Server 2012, Windows Server 2016 and Windows Server 2019.

|installation||<+> set it and forget it||<-> redo it each time you want to install a unsigned driver|
|security||<-> always allows installation of other unsigned drivers, this allowance could be used to install malicious drivers that would be unsigned, this is a very rare possibility and should not be a problem for a system running an antivirus or if the user is cautious||<+> does not permanently allow the installation of unsigned drivers|
|additional setup||<-> watermark on desktop that requires additional steps in order to hide it||<+> no watermark on desktop<-> drivers may stop functioning, requiring that you reinstall them|
|compatibility||<-> there are some applications, such as Battleye anticheat <1>, that will not work while Windows is in Test Mode|
