  "textContent": "**[What and Why:]**\n\nTo help enterprises respond quickly to critical application regressions, Microsoft is introducing a new **Downgrade Version** policy for the **Microsoft Edge WebView2 Evergreen Runtime**. This policy enables administrators to temporarily roll back WebView2 to a previous supported version (N‑1 or N‑2) on a **per‑application basis** , without disabling Evergreen updates entirely.\n\nThis change strengthens enterprise‑grade manageability, giving admins a controlled, time‑bound mitigation option while maintaining the security and update benefits of Evergreen servicing.\n\nThis message is associated with Roadmap ID 561329.\n\n**[Rollout Schedule:]**\n\nGeneral Availability (Worldwide): We will begin rolling out in **early June 2026** and expect to complete by **mid-June 2026**.\n\n**[Impact on Your Organization:]**\n\n**Who is affected:**\n\nOrganizations managing **enterprise‑managed Windows devices** (domain‑joined or MDM‑enrolled) that use **WebView2‑based applications**\n\n**Platforms/Services:**\n\n  * Windows devices\n  * Microsoft Edge WebView2 Evergreen Runtime\n  * Group Policy / MDM (msedgewebview2.admx)\n\n\n\n**What will happen:**\n\n  * A new **Downgrade Version** policy becomes available in **msedgewebview2.admx**.\n  * Admins can map specific application executables to a previous WebView2 version (N‑1 or N‑2).\n  * The **Edge Updater** installs the target version side‑by‑side.\n  * The **WebView2 Loader** redirects only the targeted apps.\n  * Downgrades **automatically expire** as new WebView2 versions are released:\n    * Apps pinned to **N‑1** remain on that version until the next release (then move forward).\n    * Apps pinned to **N‑2** revert automatically to the current Evergreen version.\n  * The policy applies only to enterprise‑managed devices.\n  * No change occurs unless the policy is explicitly configured.\n\n\n\n**[Action Required / Recommendations:]**\n\n**No action is required** before rollout.\n\nRecommended actions:\n\n  * Review existing Group Policy or registry configurations related to WebView2 to understand potential usage scenarios.\n  * Update internal incident response or app compatibility playbooks to include this downgrade option.\n  * Share guidance with application owners on when and how to request a temporary WebView2 rollback.\n\n\n\n**Learn more:** Microsoft Edge WebView2 Policy Documentation | Microsoft Learn\n\n**[Compliance considerations:]**\n\nAn admin control is added that allows configuration of WebView2 runtime versions per application. No other compliance impacts are identified.",
