Onderwerp: Windows Update - Unsafe ActiveX control

Hello,

I just tried to download the latest Microsoft security update by using the
Windows update utility in Internet Explorer. However, I could not do so
because I had disabled all ActiveX controls in the security settings (after
reading a terrifying paper on ActiveX security).

After this I enabled "Download Signed ActiveX Controls" and "Run ActiveX
controls and plugins". I ran the Windows update utility again and got this
message:
"An ActiveX control on this page is not safe. Your current security settings
prohibit running unsafe controls on this page. As a result, this page may
not display as intended."
URL: http://v4.windowsupdate.microsoft.com/en/default.asp

After I clicked "Ok", I got the error message that this utility is to run by
"Administrators Only".

I am running Microsoft Windows 2000 Server SP4 and IE 6.0.2800.1106 SP1
Q818529.

So Microsoft expects me download critical patches using an unsafe ActiveX
control??

Regards,

Siddhartha Jain

Safe for Scripting indicates that a control does not access files, memory,
or registers directly. The only purpose of the Windows Update control is to
access (and update) files directly, so it should not be marked as safe for
scripting.

You should not enable "unsafe activex", in order to get Windows Update
to work, however.

http://*.windowsupdate.com , http://download.microsoft.com,
http://windowsupdate.microsoft.com , https://download.microsoft.com, and
http://*.windowsupdate.com should all be enabled in trusted sites zone.
This is by default on Windows 2003.

Some references which are a good rule of thumb:

Windows 2003 does have a good system in this way for the paranoid. It
disables activex and activescripting, but it allows for Windows Update
to properly work. Its' settings are documented in the above url.
