List installed ConfigMgr Hotfixes automatically

I tried to store the current ConfigMgr patch state during ConfigMgr Backup automatically to make sure i can restore the exaclty configuration after a Server Crash.
Unfortunately the command wmic qfe list does only list installed Windows Updates.
If you want to to the same you can use the following command

For a 64 Bit Windows Server
reg query "HKLM\SOFTWARE\Wow6432Node\Microsoft\Updates\System Center Configuration Manager 2007\SP2" /s > ConfigMgrPatchState.txt

For a 32 Bit Windows Server
reg query "HKLM\SOFTWARE\Microsoft\Updates\System Center Configuration Manager 2007\SP2" /s > ConfigMgrPatchState.txt

You can automatically execute the command after the Backup by using the AfterBackup.bat

NULL Values in SCCM Hardware Inventory

I tried to capture the value of the registry key HKLM\SOFTWARE\YOURCOMPANY\Department from all systems independed of the OS architecture. I had the problem that the inventory delivered NULL Values in the database, although everything seemed to be configured correctly. The problem occurred very sporadic. Sometimes a system delivered a value and sometimes it didn’t.
Here’s my basic configuration.mof and sms_def.mof

configuration.mof
#pragma namespace ("\\\\.\\root\\cimv2")
#pragma deleteclass("CustomHINV86", NOFAIL)
[DYNPROPS]
class CustomHINV86
{
[key] string KeyName = "";
string Department;
};

[DYNPROPS]
instance of CustomHINV86
{
KeyName="CustomHINV";
[PropertyContext("localHKEY_LOCAL_MACHINE\\SOFTWARE\\YOURCOMPANYDepartment"),
Dynamic, Provider("RegPropProv")]
Department;
};

#pragma namespace ("\\\\.\\root\\cimv2")
#pragma deleteclass("CustomHINV64", NOFAIL)
[DYNPROPS]
class CustomHINV64
{
[key] string KeyName = "";
string Department;
};

[DYNPROPS]
instance of CustomHINV64
{
KeyName="CustomHINV";
[PropertyContext("localHKEY_LOCAL_MACHINE\\SOFTWARE\\YOURCOMPANYDepartment"),
Dynamic, Provider("RegPropProv")]
Department;
};


sms_def.mof
#pragma namespace ("\\\\.\\root\\cimv2\\SMS")
#pragma deleteclass("CustomHINV86", NOFAIL)
[SMS_Report(TRUE),
SMS_Group_Name("Your Custom HINV"),
SMS_Class_ID("YOURCOMPANYYour Custom HINV1.0"),
SMS_Context_1 ("__ProviderArchitecture=32uint32"),
SMS_Context_2 ("__RequiredArchitecture=trueboolean")]

Class CustomHINV86: SMS_Class_Template
{
[SMS_Report(TRUE),key] string KeyName;
[SMS_Report(TRUE)] String Department;
};

#pragma namespace ("\\\\.\\root\\cimv2\\SMS")
#pragma deleteclass("CustomHINV64", NOFAIL)
[SMS_Report(TRUE),
SMS_Group_Name("Your Custom HINV"),
SMS_Class_ID("YOURCOMPANYYour Custom HINV1.0"),
SMS_Context_1 ("__ProviderArchitecture=64uint32"),
SMS_Context_2 ("__RequiredArchitecture=trueboolean")]

Class CustomHINV64: SMS_Class_Template
{
[SMS_Report(TRUE),key] string KeyName;
[SMS_Report(TRUE)] String Department;
};

The result was the following entry in the SQL table

ResourceID	GroupID	RevisionID	AgentID	TimeStamp	Department0	KeyName0
33	1	3	1	14.09.2010 16:59:19	NULL	CustomHINV

That’s the problem!
As the hardware inventory listed above is designed for both OS architecture, there should be created two entries in the table. I then compared those entries with some working one, from another customization and saw the differences.
The entries were overwritten, as the column KeyName0 is not unique. This also explained the sporadic behavior. Depending on which inventory entry (32bit or 64 bit) was written into the database in which order, the first one was overwritten.
The correct entries for a 64 bit system should look like this:

ResourceID	GroupID	RevisionID	AgentID	TimeStamp	Department0	KeyName0
33	1	3	1	14.09.2010 16:59:19	NULL	CustomHINV86
33	1	3	1	14.09.2010 16:59:19	MyValue	CustomHINV64

So the result was to customize the configuration.mof file the get unique KeyName0 columns. Here it is:
#pragma namespace ("\\\\.\\root\\cimv2")
#pragma deleteclass("CustomHINV86", NOFAIL)
[DYNPROPS]
class CustomHINV86
{
[key] string KeyName = "";
string Department;
};

[DYNPROPS]
instance of CustomHINV86
{
KeyName="CustomHINV86";
[PropertyContext("localHKEY_LOCAL_MACHINE\\SOFTWARE\\YOURCOMPANYDepartment"),
Dynamic, Provider("RegPropProv")]
Department;
};


#pragma namespace ("\\\\.\\root\\cimv2")
#pragma deleteclass("CustomHINV64", NOFAIL)
[DYNPROPS]
class CustomHINV64
{
[key] string KeyName = "";
string Department;
};

[DYNPROPS]
instance of CustomHINV64
{
KeyName="CustomHINV64";
[PropertyContext("localHKEY_LOCAL_MACHINE\\SOFTWARE\\YOURCOMPANYDepartment"),
Dynamic, Provider("RegPropProv")]
Department;
};
