+

+<!--Validation-->
+**Validation procedure**
+
+The validation requires a check whether Refresh ("Keep my files") and Reset ("Remove everything") requires admin authentication in WinRE.
+The process of starting Push Button Reset (PBR) in WinRE:
+
+1. Open a cmd as Administrator, run command "reagentc /boottore" and restart the OS to boot to WinRE.
+1. OS should boot to the blue screen of WinRE UI, go through TroubleShoot -> Reset this PC, it should show two options: "Keep my files" and "Remove everything".
+
+If the MDM policy is set to "Default" (0) or does not exist, the admin authentication flow should work as default behavior:  
+
+1. Start PBR in WinRE, choose "Keep my files", it should pop up admin authentication.
+1. Click "<-" (right arrow) button and choose "Remove everything", it should not pop up admin authentication and just go to PBR options.
+
+If the MDM policy is set to "RequireAuthentication" (1)
+
+1. Start PBR in WinRE, choose "Keep my files", it should pop up admin authentication.
+1. Click "<-" (right arrow) button and choose "Remove everything", it should also pop up admin authentication.
+
+If the MDM policy is set to "NoRequireAuthentication" (2)
+
+1. Start PBR in WinRE, choose "Keep my files", it should not pop up admin authentication.
+1. Go through PBR options and click "cancel" at final confirmation page, wait unit the UI is back.
+1. Click "TroubleShoot" -> "Reset this PC" again, choose "Remove everything", it should not pop up admin authentication neither.
