Executes command defined in the Registry. Requires 3 levels of the key structure containing some keywords. Such keys may be created with two reg.exe commands, e.g. `reg.exe add HKLM\SOFTWARE\Microsoft\Provisioning\Commands\LOLBin\dummy1 /v altitude /t REG_DWORD /d 0` and `reg add HKLM\SOFTWARE\Microsoft\Provisioning\Commands\LOLBin\dummy1\dummy2 /v Commandline /d calc.exe`. Registry keys are deleted after successful execution. (Executes arbitrary command)
