HFS+ For Windows: “Driver Blocked Because It Is Not Signed Properly” Scenario. You may encounter mounting issues with driver operability on Windows 10 (system asks to format the inserted HFS+ drive). Despite the facts, that directly connected drive has Master Boot Record partitioning scheme (if it is a USB stick), does not contain Core Storage solution, and the product has been activated. Guide to quickly find and identify unsigned drivers on your Windows 10. Software Drivers are the main driving force for your system hardware, without proper.

By default, 64-bit versions of Windows Vista and later versions of Windows will load a kernel-mode driver only if the kernel can verify the driver signature. However, this default behavior can be disabled to during early driver development and for non-automated testing. Developers can use one of the following mechanisms to temporarily disable load-time enforcement of a valid driver signature. However, to fully automate testing of a driver that is installed by Plug and Play (PnP), the catalog file of the driver must be signed. Signing the driver is required because Windows Vista and later versions of Windows display a driver signing dialog box for unsigned drivers that require a system administrator to authorize the installation of the driver, potentially preventing any user without the necessary privileges from installing the driver and using the device. This PnP driver installation behavior cannot be disabled on Windows Vista and later versions of Windows.
Use the F8 Advanced Boot Option
Windows Vista and later versions of Windows support the F8 Advanced Boot Option -- 'Disable Driver Signature Enforcement' -- that disables load-time signature enforcement for a kernel-mode driver only for the current system session. This setting does not persist across system restarts.
Attach a Kernel Debugger to Disable Signature Verification
Attaching an active kernel debugger to a development or test computer disables load-time signature enforcement for kernel-mode drivers. To use this debugging configuration, attach a debugging computer to a development or test computer, and enable kernel debugging on the development or test computer by running the following command:
To use BCDEdit, the user must be a member of the Administrators group on the system and run the command from an elevated command prompt. To open an elevated Command Prompt window, create a desktop shortcut to Cmd.exe, right-click the shortcut, and select Run as administrator.
Enforcing Kernel-Mode Signature Verification in Kernel Debugging Mode
However, there are situations in which a developer might need to have a kernel debugger attached, yet also need to maintain load-time signature enforcement. For example, when a driver stack has an unsigned driver (such as a filter driver) that fails to load, which may invalidate the entire stack. Because attaching a debugger allows the unsigned driver to load, the problem appears to vanish as soon as the debugger is attached. Debugging this type of issue may be difficult.
In order to facilitate debugging such issues, the kernel-mode code signing policy supports the following registry value:
This registry value is of type REG_DWORD, and can be assigned a value based on a bitwise OR of one or more of the following flags:
0x00000001
This flag value configures the kernel to break into the debugger if a driver is unsigned. The developer or tester can then choose to load the unsigned driver by entering g at the debugger prompt.
0x00000010
This flag value configures the kernel to ignore the presence of the debugger and to always block an unsigned driver from loading.
If this registry value does not exist in the registry or has a value that is not based on the flags described previously, the kernel always loads a driver in kernel debugging mode regardless of whether the driver is signed.
Note This registry value does not exist in the registry by default. You must create the value in order to debug the kernel-mode signature verification.
Problem description: In Windows 8 and Windows 8.1 you cannot install a device driver that isn't digitally signed. The full error message is : 'Windows found driver software for your device but encountered an error while attempting to install it. The third-party INF does not contain digital signature information'. You receive this error message because in latest Windows OS, all drivers and programs must have a driver signature in order to be installed on your computer.
In Windows 7 & Vista OS you can bypass this problem and install any unsigned driver on your computer during the installation process, but in Windows 8, 8.1 OS the installation of unsigned drivers is impossible. The driver signing or digital signature is a method to verify the integrity of driver packages and to verify the identity of the vendor (software publisher) who provides the driver packages. By using Digital Signatures MS protects Windows OS from been infected from malicious codes that may be included in driver or programs.
In this guide you can find easy instructions on how you can disable driver signature enforcement in Windows 8 & Windows 7 Operating systems (both 32 & 64 bit) in case that you want to install a legitimate and trusted program on your computer.
How to disable driver signature in Windows 10, 8 (or 8.1) & Windows 7.
Step 1: Run Command Prompt with elevated rights.
Run Command Promptwith administrative privileges. to do that:
In Windows 8 or 8.1:
In Windows 7.
Step 2: Disable driver signature enforcement.
Important: If your BIOS supports Secure Boot, then DISABLE it.
In command prompt window, type these commands in order. (Press Enter after each command)
That's it.

If you want to enable signature enforcement to protect your computer from been infected, then open Command Prompt (with administrative rights) and type these commands in order:
That's all folks!
