Priya is an 8-year Windows endpoint engineer who came up through service desk tier 2 at TCS, then spent three years at Insight Enterprises building Autopilot deployment profiles for retail and healthcare clients. She moved in-house in 2023 to run desktop engineering for a 2,800-employee insurance group, where she owns the SCCM-to-Intune co-management roadmap. She writes mostly about Autopilot, Win32 app packaging with the IntuneWinAppUtil, and the very specific pain of PowerShell detection scripts that work in test rings and fail in production. Her last big project was migrating 1,400 kiosk machines off Windows 10 LTSC 2019 to Windows 11 IoT Enterprise without losing the bespoke shell launcher config - a story she still tells at user group meetups in Manchester. She holds MD-102 and SC-300 and is slowly working through the Azure Solutions Architect track on weekends.
