+        Microsoft Windows uses technologies like UAC (User Account Control) and
+        UIPI (User Interface Privilege Isolation) to prevent and/or mitigate
+        security issues. By default, UAC and and UIPI are enabled.
+      </para>
+      <para>
+        When a &product-name; VM process is running with a higher so-called
+        privilege level than another process that wants to interact with the
+        VM process via drag'n drop (or system clipboard), Windows prevents this
+        by default due to security reasons. This results in &product-name; not
+        being able to receive any Windows messages for drag'n drop.
+
+        To make this work, the &product-name; VM process must be running with
+        the same (or lower) privilege level as the process its interacting with
+        using drag'n drop.
+
+        Disabling UAC and/or UIPI is not recommended.
