A custom attribute was mistakenly created in Windows Core Library MP. This attribute is causing WMI errors on all of my servers. How can I remove the attribute from Windows Core LIbrary?

    So, the discovery causing your issue is called "Group - SEC_SRVADMIN_SERVER_SUPPORTDiscovery" and is stored in the Management Pack called "AD.Partner.Management.Pack"
    (try Get-SCOMManagementPack -Name "AD.Partner.Management.Pack" to find its displayname)

    If I were you, I would export that MP and check in the XML code what that discovery does precisely before savagely deleting it.

    Try running the following powershell command, it should give you details about the discovery that contains the wmi query :

    Get-SCOMDiscovery -Name "AttributeDiscoveryGeneratedByUIedec1a0ad2994c53bf4f6ede5ffee9b8"

    That's not returning any results

    PS C:\WINDOWS\system32> Get-SCOMDiscovery -Name "AttributeDiscoveryGeneratedByUI"
    PS C:\WINDOWS\system32>

    Removing AD.Partner.Management.Pack corrected the issue.

    Thank you very much for your help
