Hi Sarah
You’re right, keeping Edge locked down against rogue extensions is a big deal, and Microsoft’s v139 baseline update makes life easier here. The fastest way to roll those new Administrative Templates into your environment is to grab the updated ADMX package directly from the Microsoft Security Baselines repo and import it into Intune or Group Policy Central Store. Once that’s in place, you don’t need to rebuild profiles from scratch just re‑sync your existing device configuration profiles so they inherit the new policy definitions. For Intune, that means editing the profile, confirming the Edge settings node now reflects v139, and saving to push the refresh. For on‑prem GPO, it’s a simple overwrite of the ADMX files followed by a gpupdate cycle. This way, your junior admins don’t have to chase down individual settings, and compliance stays tight without manual tweaking.
