Turn on PowerShell Script Block Logging

Computer and userNative Intune settingEnableScriptBlockLogging

Supported on At least Microsoft Windows 7 or Windows Server 2008 family

What it does

This policy setting enables logging of all PowerShell script input to the Microsoft-Windows-PowerShell/Operational event log. If you enable this policy setting, Windows PowerShell will log the processing of commands, script blocks, functions, and scripts - whether invoked interactively, or through automation. If you disable this policy setting, logging of PowerShell script input is disabled. If you enable the Script Block Invocation Logging, PowerShell additionally logs events when invocation of a command, script block, function, or script starts or stops. Enabling Invocation Logging generates a high volume of event logs. Note: This policy setting exists under both Computer Configuration and User Configuration in the Group Policy Editor. The Computer Configuration policy setting takes precedence over the User Configuration policy setting.

Security baselines

Microsoft's Windows 11 v26H2 Security Baseline v2 sets this to Enabled, in its GPO “MSFT Windows 11 26H2 - Computer”.

Policy value EnableScriptBlockLogging: Sets EnableScriptBlockLogging to 1 (REG_DWORD).
Log script block invocation start / stop events: Deletes the EnableScriptBlockInvocationLogging value, so nothing is set there and the product's own default applies.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: EnableScriptBlockInvocationLogging
