Feature overview
Administrators can temporarily roll back specific applications to a previous WebView2 Evergreen Runtime version (N-1 or N-2) using the new Downgrade Version policy in msedgewebview2.admx. This policy allows enterprises to mitigate critical regressions by specifying per-application exe-to-version mappings. The Edge Updater installs the target version side-by-side, and the WebView2 Loader redirects targeted apps accordingly. Downgrades auto-expire with each new WebView2 release: apps pinned to N-1 remain on the same version (now N-2) and auto-update in the next release, while apps pinned to N-2 revert to the current Evergreen version. The policy applies only to enterprise-managed devices (domain-joined or MDM-enrolled).
