ConfigMgr Client Health is a PowerShell script that increased our patch compliance from 85% to 99%. It detects and fixes known errors in Windows and the Configuration Manager Client, and enforces required services to run and start as Automatic. The script should run in the system context on the computers you want to validate and fix. The script works with PowerShell version 5.1 and higher, and is tested on Windows 7 SP1, Windows 8.1 and Windows 10.

Current version: 0.8.1

Config.xml defines neccesary configuration for script to run. Use it to specify sitecode, management point, client source share, and specific errors to detect and fix. Store config.xml on a network share to easy update settings. Run with at least administrator priveleges. Corrupt WMI fix requires SYSTEM priveleges.

ConfigMgr Client Health stores the result of the health check in an SQL database and/or log files to a file share.

Example: ConfigMgrClientHealth.ps1 -Config \\server\share\config.xml -Webservice http://server/ConfigMgrClientHealth
