Deprecation: Windows CPU plugin attribute changes. (OHAI-5)
The Windows Ohai plugin has been updated to correctly return CPU information. Previously the CPU plugin reported a model_name value, which was actually the CPU’s description and not the actual model name. Ohai now reports the proper name value for model_name and provides description with the previous description value. This behavior aligns CPU plugin behavior between *nix and Windows hosts in Chef.
Remediation
If you rely on the format of a CPU model_name value such as node['cpu'['0']['model_name'] you will need to update your cookbook code to reference node['cpu']['0']['description'] instead.
