# User Option Settings

The optional User Options registry settings control additional service options. These settings reside under the subkey:

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\Research\Options

Note These settings cannot be set through the user interface.

Entry name | Value type | Value data | Required? | Default value
--- | --- | --- | --- | ---
GroupTimeout | DWORD | Integer denoting the number of milliseconds before a time-out occurs when searching more than one service. | No | 60000
Timeout | DWORD | Integer denoting the number of milliseconds before a time-out occurs when searching only one service. | No | 120000
DiscoveryNeedOptIn | DWORD | Boolean used to ask the user to opt in to the discovery mechanism. This setting is irrelevant if NoDiscovery is set to 1. The HKEY_CURRENT_USER version of this value overrides the HKEY_LOCAL_MACHINE value. Possible values include: True (1). Ask the user to opt in to the discovery mechanism. False (0). Enable the discovery mechanism without asking the user. | No | False is assumed if absent.
