+Remove `WebDAV` modules and handlers from the `Web.config` file.
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<configuration>
+  <system.webServer>
+    <modules>
+      <remove name="WebDAVModule" />
+    </modules>
+    <handlers>
+      <remove name="WebDAV" />
+    </handlers>
+  </system.webServer>
+</configuration>
+```

+2. In the Windows Features window, expand Internet Information Services -> World Wide Web Services -> Common HTTP Features.
