Windows have a built-in tool called “Driver Verifier Manager“. This tool is built to verify and validate device drivers installed on Windows System. Driver Verifier Manager is capable of a variety of functions such as displaying all drivers installed on the computer, Signed and unsigned driver list, schedule & verifying drivers, etc.

boot.
/driver <name> [<name> ...]
Specifies one or more drivers (image names) that will be verified.
Wildcard values (e.g. n*.sys) are not supported.
/driver.exclude <name> [<name> ...]
Specifies one or more drivers (image names) that will be excluded
from verification. This parameter is applicable only if all drivers

/flags <options> [<options> ...]
Specifies one or more options that should be enabled for verification.
Flags are applied to all drivers being checked by Driver Verifier. The
provided options values must be either in decimal, hexadecimal ("0x"
prefix), octal ("0o" prefix) or binary ("0b" prefix) format.
Standard Flags:
Standard Driver Verifier options can be specified using '/standard'.

/ruleclasses or /rc [<ruleclass_1> <ruleclass_2> ... <ruleclass_k>]
This parameter is larger set of '/flags' above. While '/flags' is
limited to 32 bit bitmap expression, this can include more than 32
verification classes. Each positive decimal integer represents a
verification class. Multiple classes can be expressed by separating
each class id with space character. Following rule classes IDs are
available and leading 0's can be omitted.
Standard Rule Classes:
1 - Special pool
2 - Force IRQL checking
4 - Pool tracking
5 - I/O verification
6 - Deadlock detection
8 - DMA checking
9 - Security checks
12 - Miscellaneous checks
18 - DDI compliance checking
34 - WDF Verification
Additional Rule Classes:
These rule classes are intended for specific scenario testing. Rule
classes are marked with (*) require I/O Verification (5) that will
be automatically enabled. Flags marked with (**) support disabling
of individual rules.

/log.code_integrity
This option suppresses Code Integrity violation breaks and collects
only statistics for verified drivers. Statistics could be extracted
via /log option or kernel debugger. This parameter is applicable only
if Code Integrity checks are enabled.
/rules {query | reset | default <id> | disable <id>}
Specifies rules level control (advanced).
query Shows current status of controllable rules.
reset Resets all rules to their default state.
default <id> Sets rule ID to its default state.
disable <id> Disables specified rule ID.
/query
Display runtime Driver Verifier statistics and settings.
/querysettings
Displays a summary of the options and drivers that are currently
enabled, or options and drivers that will be verified after the
next boot. The display does not include drivers and options added
using /volatile.
/bootmode
Specifies the Driver Verifier boot mode. This option requires system
reboot to take effect.
persistent Ensures that Driver Verifier settings are
persistent across reboots. This is the default
value.
resetonbootfail Disables Driver Verifier for subsequent reboots
if the system failed to start.
resetonunusualshutdown
Driver Verifier persists until unusual shutdown
happens. Its abbrevation, 'rous', can be used.
oneboot Enables Driver Verifier only for the next boot.
/persistthroughupgrade
Makes the Driver Verifier settings persist through upgrade. Driver
Verifier will be active during system upgrade.
/reset
Clears Driver Verifier flags and driver settings. This option requires
system reboot to take effect.
/faults [probability [pool_tags [applications [delay_minutes]]]]
Enable the Randomized low resources simulation feature and optionally
control parameters for the Randomized low resources simulation.
Probability Specifies the probability that Driver Verifier will
fail a given allocation. The value represents the
number of chances in 10,000 that Driver Verifier will
fail the allocation. The default value 600, means
600/10000 or 6.
Pool Tags: Specifies a space separated list of the pool tags to
be injected with faults. By default, any pool
allocation can be injected with faults.
Applications Specifies a space separated list of image file names
(an executable) that will be injected with faults. By
default, any pool allocation can be injected with
faults.
DelayMinutes Specifies the number of minutes after booting during
which Driver Verifier does not intentionally fail any
allocations. This delay allows the drivers to load
and the system to stabilize before the test begins.
The default value is 8 minutes.
/faultssystematic [<options> ...]
Controls the Systematic low resources simulation parameters.
enableboottime Enables fault injections across reboots.
disableboottime Disables fault injections across reboots.
This is the default value.
recordboottime Enables fault injections in 'what if' mode
across reboots.
resetboottime Disables fault injections across reboots and
clears the stack exclusion list.
enableruntime Dynamically enables fault injections.
disableruntime Dynamically disables fault injections.
recordruntime Dynamically enables fault injections in
'what if' mode.
resetruntime Dynamically disables fault injections and
clears the previously faulted stack list.
querystatistics Shows the current fault injection statistics.
incrementcounter Increments the test pass counter used to
identify when a fault was injected.
getstackid <counter> Retrieves the indicated injected stack id.
excludestack <stack_id> Excludes the stack from fault injection.
/log <file_name> [/interval <seconds>]
Creates a log file with the specified name and periodically writes the
runtime statistics to this file. The interval between log file updates
is controlled by the '/interval' parameter. The default value is 30
seconds. Use CTRL+C to close the log and return.
/volatile
Changes Driver Verifier settings without rebooting the computer.
Volatile settings take effect immediately and are in effect until the
next system reboot.
/volatile /adddriver <name> [<name> ...]
Starts the verification for the specified driver or drivers.
/volatile /removedriver <name> [<name> ...]
Stops the verification for the specified driver or drivers.
/domain {wdm | ndis | ks | audio} [rules.all | rules.default] /driver ...
[/logging | /livedump]
Controls the verifier extension settings. The following verifier
extension types are supported:
wdm Enabled verifier extension for WDM drivers.
ndis Enabled verifier extension for networking drivers.
ks Enabled verifier extension for kernel mode
streaming drivers.
audio Enabled verifier extension for audio drivers.
The following extension options are supported:
rules.default Enables default validation rules for the selected
verifier extension.
rules.all Enables all validation rules for the selected
verifier extension.
/logging
Enables logging for violated rules detected by the selected verifier
extensions.
/livedump
Enables live memory dump collection for violated rules detected by
the selected verifier extensions.
