Sentinelctl.exe Unload May 2026
The sentinelctl.exe unload command is a powerful administrative function within the SentinelOne Agent command-line interface, used to temporarily disable and unload the agent’s services and drivers from a Windows endpoint. This action effectively stops the agent's protection capabilities, which is typically necessary for troubleshooting, performing specific system updates, or preparing a machine for an uninstallation that requires offline verification. Purpose and Usage
Navigate to the SentinelOne installation directory (usually C:\Program Files\SentinelOne\Sentinel Agent [Version]\) or simply call the executable if it's in your path. Use the following syntax: sentinelctl.exe unload -k "YOUR_PASSPHRASE_HERE" Use code with caution. The -k flag stands for the "key" or passphrase. 4. Verify the Status Sentinelctl.exe Unload
