Report list computer if not exist registry key

[BryceB]

Hello,

I would like to list all computers that do not have this registry key :
Regkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\ValidCommunities
Valuename: TEST
Value: 4

This report will be used to deploy the package that configures SNMP Comunity with this registry key.

Can I use an IF exist or equivalent ...?

thanks

I would also like to know how to run a report that looks for IF a registry key exists. I have a deployment to do on machines where it does not exist. I can scan for the key, but nothing comes back on machines where it does not exist. Is there a way to get a negative scan result to make a report on machines needing the registry update?
Thanks.
