my playbook running on ansible automation platform and using setup to gather facts from windows server . the job template configuration don’t make any modification on playbook ,execution environment .

in 5/6/2026 , gather facts can return ansible\_os\_name properly .  
“ansible\_os\_name”: “Microsoft Windows Server 2019 Datacenter”,

but gather facts return null on 5/28/2026 .  
“ansible\_os\_name”: null,

any ideas for this strange issue ?  
Thanks

There was a bug in the 3.6.0 release of `ansible.windows` that caused some facts to not be set [ansible\_distribution will be null with version 3.6.0 · Issue #900 · ansible-collections/ansible.windows · GitHub](https://github.com/ansible-collections/ansible.windows/issues/900). I’ve pushed out 3.6.1 of `ansible.windows` that fixes this issue so please make sure you are on that version of the collection.
