Driver Verifier is a built in diagnostic tool in Windows 10. While designed to verify both native Microsoft drivers and third party drivers, in this tutorial I will be demonstrating this tool with. To disable Driver Verifier and go back to normal settings, open the Driver Verifier application again, select “Delete Existing Settings,” click “Finish,” and reboot your PC. If your computer crashes every time it boots and you can’t disable Driver Verifier, try booting into Safe Mode, launching Driver Verifier, and telling it to delete existing settings. You should then be able to boot your PC normally.
Driver Verifier monitors Windows kernel-mode drivers and graphics drivers to detect illegal function calls or actions that might corrupt the system. Driver Verifier can subject the Windows drivers to a variety of stresses and tests to find improper behavior.
You can run Driver Verifier on multiple drivers simultaneously, or on one driver at a time. You can configure which tests to run, which allows you to put a driver through heavy stress loads or through more streamlined testing.
Where can I download Driver Verifier.
You don t need to. Driver Verifier Verifier.exe is included in every version of Windows, starting with Windows 2000 in the windir system32 directory. There isn t a separate Driver Verifier download package.
Open a Command Prompt window Run as administrator.
Type verifier to open the Driver Verifier Manager, or type verifier /. to view command line options. See Driver Verifier Command Syntax for more information.
Caution
Running Driver Verifier could cause the computer to crash.
You should only run Driver Verifier on computers you are using for testing and debugging.
You must be in the Administrators group on the computer to use Driver Verifier.
For information about changes in Driver Version for Windows 8.1 and previous versions of Windows, see Driver Verifier: What s New.
When to use Driver Verifier
Run Driver Verifier throughout the driver development and test process.
Use Driver Verifier to find problems early in the development life cycle, when they are easier and less costly to correct.
Use Driver Verifier when you deploy a driver for testing using the WDK, Visual Studio, and the Windows Hardware Certification Kit HCK tests. See Testing a Driver.
Use Driver Verifier for troubleshooting and debugging test failures and computer crashes.
How to start Driver Verifier
You should only run Driver Verifier on test computers, or computers you are testing and debugging. To get the most benefit from Driver Verifier, you should use a kernel debugger and connect to the test computer. See Windows Debugging.
Open a Command Prompt window Run as administrator and type verifier to open the Driver Verifier Manager.
Select Create standard settings default and click Next.
You can also choose Create custom settings to select from predefined settings, or to select individual options. See Driver Verifier Options and Selecting Driver Verifier Options for more information.
Select a driver or drivers to verify.

Automatically select all drivers installed on this computer
Provides maximum coverage in terms of the number of drivers that are tested on a system. This option is useful for test scenarios where a driver can interact with other devices or drivers on a system.
This option can also exhaust the resources available for Special Pool and some resource tracking. Testing all drivers can also adversely affect system performance.
Select driver names from a list
Microsoft Verified Apps Disable
In most cases, you will want to specify which drivers to test.
Selecting all drivers in a device stack allows the Enhanced I/O Verification option to track objects and check compliance as an IRP is passed between each of the drivers in the stack and allows for a greater level of detail to be provided should an error be found.
Select a single driver if you are running a test scenario that measures system or driver performance metrics, or if you want to allocate the greatest number of resources available for detecting memory corruption or resource tracking issues deadlocks, mutexs. The Special Pool and I/O Verification options will be more effective when used on one driver at a time.
Click Finish and reboot the computer.
Note You can also run Driver Verifier in a Command Prompt window. For example, to run Driver Verifier with the standard settings on a driver called myDriver.sys, you would use the following command:
verifier /standard /driver myDriver.sys
See Driver Verifier Command Syntax for more information.
How to control Driver Verifier stop, reset, and view settings and status
To stop or reset Driver Verifier
Select Delete existing settings.
Reboot the computer.
Or type the following command in a Command Prompt window and reboot the computer.
To view Driver Verifier settings
Select Display existing settings.
Or type the following command in a Command Prompt window.
To view Driver Verifier statistics
Select Display information about the currently verified drivers.
How to debug Driver Verifier violations
To get the most benefit from Driver Verifier, you should use a kernel debugger and connect to the test computer. See Windows Debugging for more information.
If Driver Verifier detects a violation, it generates a bug check to stop the computer. This is to provide you with the most information possible for debugging the issue. When you have a kernel debugger connected to a test computer running Driver Verifier, if Driver Verifier detects a violation, Windows breaks into the debugger and displays a brief description of the error.
All Driver Verifier violations result in bug checks, the most common ones although not necessarily all of them are:
For more information see Handling a Bug Check When Driver Verifier is Enabled. For tips about debugging Bug Check 0xC4, see Debugging Bug Check 0xC4: DRIVER_VERIFIER_DETECTED_VIOLATION.
When you start a new debug session, use the debugger extension command. analyze. In kernel mode, the. analyze command displays information about the most recent bug check. The. analyze -v command displays additional information and attempts to pinpoint the faulting driver.
In addition. analyze, you can use the following debugger extensions to view information specific to Driver Verifier:
.verifier dumps captured Driver Verifier statistics. Use. verifier -. to display all of the available options.
.deadlock displays information related to locks or objects tracked by Driver Verifier s deadlock detection feature. Use. deadlock -. to display all of the available options.
.iovirp address displays information related to an IRP tracked by I/O Verifier. For example:
.ruleinfo RuleID displays information related to the DDI compliance checking rule that was violated RuleID is always the first argument to the bug check. All DDI Compliance Checking RuleID are in the form 0x200nn.

Driver Verifier: What's New
Today I found a program called Windows Driver Verifier in Windows Components. On Windows I could determine that it is the Verifier.exe process.
Driver Verifier is available in all versions of Windows starting with Windows 2000. Each version introduces new features and checks for finding bugs in Windows drivers. This section summarizes the changes and provides links to related documentation.
Driver Verifier in Windows 10
Updated: July 29, 2015
Starting with Windows 10, driver verifier includes new driver validation rules for the following technologies:
Driver Verifier in Windows 8.1
Updated: June 17, 2013
Starting with Windows 8.1, Driver Verifier introduces four new options for detecting errors.
Driver Verifier in Windows 8
Updated: October 20, 2012
Starting with Windows 8, Driver Verifier introduces five new options for detecting errors.
The Power Framework Delay Fuzzing option inserts random execution delays to help detect concurrency bugs in drivers that use the power management framework PoFx. The execution delays have upper-time limits. This option is not recommended for drivers that do not directly utilize the power management framework PoFx.
The DDI compliance checking option applies the same device driver interface DDI usage rules that Static Driver Verifier uses to verify that your driver makes function calls at the required IRQL for the function. The DDI compliance checking is run as part of the standard Driver Verifier options.
The Invariant MDL Checking for Stack option monitors how the driver handles invariant MDL buffers across the driver stack.
The Invariant MDL Checking for Driver option monitors how the driver handles invariant MDL buffers on a per-driver basis.
The Stack Based Failure Injection option injects resource allocation failures in kernel mode drivers.
When you build, deploy, and test your driver using Visual Studio 2012 and the WDK for Windows 8, you can also configure Driver Verifier to run on a test computer when you deploy your driver for testing.
Driver Verifier in Windows 7
Updated: October 22, 2012
For information about new features that were added in Windows 7, see the white paper Driver Verifier in Windows 7.
For Windows 7, Driver Verifier has been enhanced with new tests and features that allow Driver Verifier to expose more classes of typical driver bugs.
Incorrect References to User Handles from Kernel Drivers
I/O Verification Improvements
Special Pool, Pool Tracking, and Low Resources Simulation Improvements
Incorrect Usage of Synchronization Mechanisms
Incorrect Object References
Pool Quota Charges from DPC Routine
System Shutdown Blocks or Delays
Improved Force Pending I/O Requests
In Windows 7, Driver Verifier provides checks for queued spin locks, these checks resemble those provided to spin locks in earlier Windows versions. These checks include the following:
Verifying that an operation that should raise the interrupt request level IRQL value, such as KeAcquireInStackQueuedSpinLock, is not actually lowering the IRQL value.
Verifying that an operation that should lower the IRQL value, such as KeReleaseInStackQueuedSpinLock, is not actually raising the IRQL value.
Trimming the System process s working set if the Force IRQL Checking option is enabled, when the IRQL is being raised to DISPATCH_LEVEL or above, in an attempt to expose possible references to pageable memory while the driver is running at elevated IRQL.
Predicting possible deadlocks when the Deadlock Detection option is enabled.
Trying to use the same KSPIN_LOCK data structure both as a spin lock and as a stack queued spin lock when the Deadlock Detection option is enabled.
Checking for obviously incorrect pointer values, such as a user-mode virtual address that is used as a spin lock address.
Logging IRQL transitions in the Driver Verifier IRQL log. This information appears when you use the. verifier 8 extension of the Windows Debuggers.
See. verifier.
Additional Debugging Information
In Windows 7, Driver Verifier provides the following additional information that is useful for debugging:
There is a log with stack traces in chronological order for recent calls to KeEnterCriticalRegion and KeLeaveCriticalRegion from verified drivers. The log contents are displayed by using the. verifier 0x200 debugger extension of the Windows Debuggers. This information can be useful for understanding scenarios in which a thread is unexpectedly running in a critical region or is trying to leave a critical region that it has left already.
You can display additional information from the Force Pending I/O Requests Log by using the. verifier 0x40 debugger extension. In earlier Windows versions, the log contained just one stack trace for each IRP that Driver Verifier forced to be pending. This was the stack trace from the time when IoCompleteRequest was called for the first time for the forced pending IRP. Windows 7 has at least two log entries, possibly more than two, for each forced pending IRP:
Stack trace at the time when Driver Verifier picked the IRP to be forced pending. Driver Verifier chooses some of the IRPs to be forced pending when one of the verified drivers calls IoCallDriver.
Stack traces for each IoCompleteRequest call for the forced pending IRP before the completion reaches the verified driver. More than one IoCompleteRequest call can exist for the same IRP because one of the drivers can temporarily stop the completion from its completion routine and then resume it by calling IoCompleteRequest again.
There are more valid stack traces in the IRQL Transition log. This log is displayed by using. verifier 8. In Windows versions earlier than Windows 7, Driver Verifier could have tried to log some of these stack traces at elevated IRQL and failed to capture the stack trace because of the high IRQL value. In Windows 7, Driver Verifier tries to capture these stack traces:
In this way, Driver Verifier can capture more of these IRQL transition stack traces.
.analyze can triage issues that are exposed by the Enhanced I/O Verifier checks that are part of I/O Verifier in Windows 7. In earlier Windows versions, the Enhanced I/O Verifier error reporting consisted of displaying a description of the driver defect that was detected by Driver Verifier followed by a break into debugger. Running. analyze after such a break does not result in meaningful triage for many of these breaks because. analyze cannot use the information from the error description text that appears in the debugger. In Windows 7, the meaningful information about these driver defects is saved by Driver Verifier in memory. analyze can find this information and perform a much more meaningful automatic triage for many of these breaks.

You don t need to. Driver Verifier Verifier.exe is included in every version of Windows, starting with Windows 2000 in the windir system32 directory.
Driver Verifier Manager helps in monitoring the kernel mode drivers in Windows systems. The Driver Verifier Manger is also responsible to identify inappropriate calling of different functions that may harm the system.
Driver Verifier Manager helps to detect the improper working of various Windows drivers as it includes variety of stress tasks. Driver Verifier was launched as a command line utility application in the earlier version of Windows. However, Windows modified this application to a Graphical User Interface called the “Driver Verifier Manager” in which a user has the option to perform custom set of settings for testing and verifying drivers. Whenever the Driver Verifier Manager detects a violation in its drivers, it initiates a bug check to stop the computer. It also provides different options for code developers as they use to test and verify various system drivers for proper working of their applications. So, it is versatile in nature.
Windows 10 possess different options to access Driver Verifier Manager; some of them are discussed below:
Option 1: Through Windows Search Bar
Type “verifier” in Windows Search Bar located on the lower left corner of your screen. Click on the first option provided.
Option 2: Through Run Dialog Box
Press “Windows Key+R” to open the Run Command Dialog Box. Type “verifiergui” in the command line and Press Enter or hit “OK” button.
