Inspecting DSC Configuration and Status Retention Settings

Once the folder size is known, inspect how DSC is configured and whether it should be removing old status records.

Check the types of files stored in the status folder:

Get-ChildItem "C:\Windows\System32\Configuration\ConfigurationStatus" |
    Group-Object Extension |
    Sort-Object Count -Descending |
    Select-Object Count, Name

This provides insight into what DSC is generating and whether unexpected file types are present.

Review the Local Configuration Manager (LCM) configuration:

Get-DscLocalConfigurationManager | Select-Object *

Pay particular attention to:

Finally, inspect the recorded DSC execution history:

Get-DscConfigurationStatus -All

If DSC reports deserialization errors, the status history or DSC state information may be corrupted and additional repair steps will be required.
