Underneath the 组 key is a list of user groups who have entries in the policy file. Since a user may belong to many groups and those groups may have conflicting settings, it is important to specify an order in which groups are processed. This order is contained in the GroupData\优先 key, which has values in the form "1"="【组名】", "2"="【组名】", and so on. "1" is highest priority, and the priority diminishes as the number in the value name increases. The downloader reads the group priority values and then processes groups from lowest priority to highest; that is, the downloader begins with the highest numbered value and works to the value "1".
对于优先级列表中的每个组，下载程序确定用户是否是该组的成员。如果用户在组中，下载程序应尝试在组键下找到组名称的密钥。如果存在这样的键，则下载程序将该键下的注册表图像合并到HKEY_CURRENT_USER键中。如果在优先级列表中指定了组，但没有组键下的条目，则不是错误;这只是意味着没有任何反应。优先级列表中的每个组重复此过程。（如果组中有组键下的条目，但在优先级列表中没有条目，则不会处理该条目。）
