Windows 11 Removes WMIC Completely With September Update

Microsoft has fully removed WMIC (Windows Management Instrumentation Command-line) from Windows 11 with KB5124008, the September 2026 security update.

Microsoft had already announced plans to remove WMIC, but the September 2026 Update completes the process.

WMIC no longer ships with Windows 11, and Microsoft has also removed it as a Feature on Demand. Organizations that still rely on WMIC should move their apps, scripts, and administrative workflows to supported alternatives.

Microsoft removes a tool often abused by ransomware

WMIC served as a legitimate Windows administration utility for years, but attackers also used it extensively in malware and ransomware campaigns.

Ransomware could use WMIC commands to delete Windows Shadow Volume Copies, removing one recovery option after encrypting files. Attackers could also use the utility as part of scripts that gathered system information or changed Windows configurations.

Removing WMIC from Windows 11 means malware can no longer assume the command-line utility exists on every updated system.

Malware also used WMIC against Microsoft Defender

Attackers have also used WMIC to check whether Microsoft Defender was running and interact with security-related Windows settings.

Its removal therefore eliminates another built-in tool that malware could abuse during an attack.

However, removing WMIC does not block every technique that attackers previously performed through the utility. Organizations still need standard endpoint protections, patching, and monitoring.

Microsoft still offers WMIC for legacy compatibility

Organizations with older software or scripts can still restore WMIC through a downloadable package from Microsoft.

Microsoft recommends using that option only as a temporary compatibility measure while administrators migrate legacy workloads away from WMIC.

Users who do not explicitly need the tool should avoid reinstalling it. They should also treat requests from unknown apps or websites to download WMIC with caution.

For most Windows 11 users, KB5124008 marks the end of WMIC as a built-in Windows administration tool.
