SILENTTRINITY can use the `GetRegValue` function to check Registry keys within `HKCU\Software\Policies\Microsoft\Windows\Installer\AlwaysInstallElevated` and `HKLM\Software\Policies\Microsoft\Windows\Installer\AlwaysInstallElevated`. It also contains additional modules that can check software AutoRun values and use the Win32 namespace to get values from HKCU, HKLM, HKCR, and HKCC hives.
