The "SuppressionPolicy" key is referenced in many posts and web sites
but I've not been able to find any information about the key's nature
and what the valid DWORD values are. I've looked through five
different (thick) registry reference books; searched for the term on
Google, Ask, Technorati, Yahoo and others; and have plowed through the
UseNet. No details on this key anywhere. Nevertheless, using the key
seems to be the solution to a number of different issues.

Can anyone point me in the right direction?

Thanks!

SuppressionPolicy is a Value Name.

This is a registry key...
HKEY_CLASSES_ROOT\*\Shellex\PropertySheetHandlers\CryptoSignMenu

The registry stores data in a tree format. Each node in the tree is called a
key. Each key can contain both subkeys and data entries called values.
Sometimes, the presence of a key is all the data that an application
requires; other times, an application opens a key and uses the values
associated with the key. A key can have any number of values, and the values
can be in any form.

Each of the trees under My Computer is a key. The HKEY_LOCAL_MACHINE key has
the following subkeys: HARDWARE, SAM, SECURITY, SOFTWARE, and SYSTEM. Each
value consists of a value name and its associated data, if any.

Verbs can be suppressed through policy settings by adding a
SuppressionPolicy value to the verb's key. Set the value of
SuppressionPolicy to the policy ID. If the policy is turned on, the verb and
its associated shortcut menu entry are suppressed. For possible policy ID
values, see the RESTRICTIONS enumeration.

Verbs are commands, like Open, Explorer or Search (Find) in a context menu.

I found eight instances of SuppressionPolicy on my machine.

HKLM\SOFTWARE\Classes\CLSID\{208D2C60-3AEA-1069-A2D7-08002B30309D}\

SuppressionPolicy REG_DWORD 0x00000080 (128)
{208D2C60-3AEA-1069-A2D7-08002B30309D} = My Network Places

Right click My Network Places and Open, Explore and Search for Computers are
the choices.

One possible restricion is REST_HASFINDCOMPUTERS.
If nonzero, the system administrator has disabled the ability to search for
computers on the network. Applications should remove the ability to search
for computers on the network.
