The function of the executable is revealed by unpacking its name: PS Mini Session Executable . The "Mini Session" refers to a lightweight, isolated session that the PC-Doctor software creates to perform diagnostics without interfering with the primary user session. When a technician initiates a remote hardware scan—checking for failing RAM, a degrading hard drive, or thermal issues—the main application spawns psminitsessionexe to handle the low-level, sensitive interactions with the hardware. This process acts as a bridge, running with elevated privileges to access SMBIOS data, S.M.A.R.T. drive attributes, and temperature sensors, then securely reporting the results back to the main diagnostic interface.

No. If you kill or disable , users will lose the ability to connect to remote targets via CyberArk. It is a critical "bridge" component for secure, audited access. If the process is consuming high CPU, it is better to investigate the specific RDP session or target application rather than terminating the executable itself.
Do simply delete the file or kill the process via Task Manager if your computer is managed by an employer. You could break your ability to access required systems or violate security policies. This process acts as a bridge, running with
The file is a specific executable component primarily associated with CyberArk Privileged Session Manager (PSM) . If you’ve spotted this process running in your environment or found it while auditing your server's Task Manager , it is usually a sign that a privileged remote session is being initialized.
psminitsessionexe is a legitimate and necessary component of the Puppet configuration management tool on Windows. It solves a complex technical problem: safely executing automation scripts inside the isolated Session 0 environment.
