Silent Install Process Hacker with driver + taskmgr replacement

[teknixstuff]

What arguments are required to install process hacker 2.39 with the driver and taskmgr replacement enabled?

[Advait251206]

For Process Hacker 2.39, the installer is based on Inno Setup and supports silent installation switches such as:

processhacker-2.39-setup.exe /VERYSILENT /SUPPRESSMSGBOXES /NORESTART

To enable both the KProcessHacker driver and Task Manager replacement during installation, the commonly documented tasks are:

processhacker-2.39-setup.exe /VERYSILENT /NORESTART /MERGETASKS=create_kph_service,set_default_taskmgr

Where:

• create_kph_service = installs the KProcessHacker driver/service.
• set_default_taskmgr = configures Process Hacker as the Task Manager replacement.

Alternatively, if the driver was not installed during setup, Process Hacker also exposes command-line options to install it later:

ProcessHacker.exe -installkph

and remove it with:

ProcessHacker.exe -uninstallkph

So the command I'd try first is:

processhacker-2.39-setup.exe /VERYSILENT /SUPPRESSMSGBOXES /NORESTART /MERGETASKS=create_kph_service,set_default_taskmgr

If you're deploying this in an enterprise environment, I'd recommend testing on a VM first, since the available installer tasks can vary slightly between builds and forks of Process Hacker. :contentReference[oaicite:3]{index=3}
