A simple command line utility to quickly load and unload Windows drivers
Basically, you just pass a path to the driver you want to load. For example: KLoad.exe C:\Windows\System32\ARandomDriver.sys
In addition, if you are loading a filter driver you can pass an altitude value after the driver path. See here for more information.
To unload pass "unload" as the driver name followed by the service key name. Example: KLoad.exe unload Random.sys
This will target the registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Random.sys
and attempt to unload the driver at this key.
Please note that not all (especially filter) drivers are designed to be unloaded.
