[]
This section is an add-registry-section, whose entries satisfy the following format :

[add-registry-section]
reg-root, [subkey], [value-entry-name], [flags], [value]

An HKR specification in such an add-registry section designates the ..Class\{SetupClassGUID}\device-instance-id registry path to the user-accessible driver (a.k.a. "software" key).

Processing this section will add into the registry under HKR, current subkey, the values :

CLSID (szString) <- %Proxy.CLSID%
FriendlyName (szString) <- %AC97SMPL.Wave.szPname%

The string tokens are defined as follows :

[Strings]
...
Proxy.CLSID="{17CCA71B-ECD7-11D0-B908-00A0C9223196}"
...
AC97SMPL.Wave.szPname="AC'97 Sound Card"

and their localized versions :

[Strings.0407]
...
Proxy.CLSID="{17CCA71B-ECD7-11D0-B908-00A0C9223196}"
...
AC97SMPL.Wave.szPname="AC'97 Sound Card"
