Reinstall SCCM Client on Windows 11 Workstation

Question

SCCM did not install properly on a newly imaged system and need to reinstall SCCM on a Windows 11 workstation.

Answer 1

Hello Robert,

Below is a step-by-step guide you can follow whenever a newly imaged Windows 11 PC needs a fresh ConfigMgr/SCCM client install.

I) Uninstall the existing client

1. Open an elevated PowerShell or CMD window: Win + X → Terminal (Admin)
2. Run the built-in uninstall command: ccmsetup /uninstall
3. Wait for the process to finish: Watch C:\Windows\ccmsetup\Logs\ccmsetup.log until you see the entry CcmSetup is exiting with return code 0.

II) Remove leftovers (recommended)

Action	Purpose
Delete C:\Windows\CCM and C:\Windows\ccmsetup	Clears any corrupt files
Delete C:\Windows\CCM and C:\Windows\ccmsetup	Clears any corrupt files
Delete C:\Windows\CCMCache	Frees disk space & resets cache
Open Services.msc and stop SMS Agent Host (if still running)	Ensures no handles are open

(Rare) WMI repair:

winmgmt /verifyrepository

If “WMI repository is inconsistent,” run winmgmt /salvagerepository | Fixes WMI errors that prevent re-enrollment |

Reboot once the cleanup is complete.

III) Reinstall the client

A) Manual install (works offline)

\\<SiteServer>\SMS_<SiteCode>\Client\ccmsetup.exe ^
  /mp:<MP_FQDN> ^
  SMSSITECODE=<SiteCode> ^
  SMSMP=<MP_FQDN> ^
  /source:\\<SiteServer>\SMS_<SiteCode>\Client ^
  /skipprereq:scclient_x64.msi	

• Replace <SiteCode> (e.g., ABC) and <MP_FQDN> with your values.
• Add /logon if you want it to pick up AD site assignment automatically.
• If the device is on the VPN, use the VPN-resolvable FQDN.

B) Client Push from the console

• Assets and Compliance → Devices → Right-click PC → Install Client
• Tick “Uninstall existing ConfigMgr client” and “Restart if required”.

IV) Verify a healthy install

1. Logs
   • C:\Windows\ccmsetup\Logs\ccmsetup.log -> look for Return code 0.
   • C:\Windows\CCM\Logs\ClientIDManagerStartup.log -> look for “Successfully registered.”
2. Control Panel -> Configuration Manager should show:
   • Correct Site Code under Site Tab.
   • Client Version matches your current release (e.g., 5.00.9128.1000).
3. Console status -> Device should flip to “Active” and “Client = Yes” within a few minutes.
