During January 2025, Per Larsen updated the MicrosoftDocs/memdocs repository to clarify Windows 11 compatibility for Endpoint Security App Control Policies. He focused on improving the accuracy and maintainability of the documentation by revising endpoint-security-app-control-policy.md using Markdown and Git-based workflows. His work addressed potential confusion for administrators by providing clear guidance on supported Windows versions, reducing the likelihood of support requests related to OS compatibility. Although the contribution was limited to a single targeted documentation feature and did not involve bug fixes, it demonstrated careful attention to detail and a strong understanding of documentation best practices within the endpoint security domain.
