4 <title>Drag'n Drop not Working</title>

8 Microsoft Windows uses technologies like UAC (User Account Control) and
9 UIPI (User Interface Privilege Isolation) to prevent and/or mitigate
10 security issues. By default, UAC and UIPI are enabled.
11 </p>
12 <p>
13 When an <ph conkeyref="vbox-conkeyref-phrases/product-name"/> VM process is running with a higher so-called
14 privilege level than another process that wants to interact with the
15 VM process via drag'n drop (or system clipboard), Windows prevents this
16 by default due to security reasons. This results in <ph conkeyref="vbox-conkeyref-phrases/product-name"/> not
17 being able to receive any Windows messages for drag'n drop. To make this work,
18 the <ph conkeyref="vbox-conkeyref-phrases/product-name"/> VM process must be running with
19 the same (or lower) privilege level as the process it is interacting with
20 using drag'n drop.</p>
21
22 <p>Disabling UAC and/or UIPI is not recommended.
