其中有一段关于它的描述：
Assign the Deny log on locally logon right to the built - in Support account - the Support_388945a0 account is the logon account for Remote Assistance.
Note: The Support_388945a0 account enables Help and Support Service interoperability with signed scripts. This account is primarily used to control access to signed scripts that are accessible from within Help and Support Services. Administrators can use this account to delegate the ability for an ordinary user, who does not have administrative access over a computer, to run signed scripts from links embedded within Help and Support Services. These scripts can be programmed to use the Support_388945a0 account credentials instead of the users credentials to perform specific administrative operations on the local computer that otherwise would not be supported by the ordinary users account. When the delegated user clicks on a link in Help and Support Services, the script will execute under the security context of the Support_388945a0 account. This account has limited access to the computer and is disabled by default.
译文：
Support_388945a0帐户是用于远程协助的帐户，系统拒绝使用它进行本地登陆。
注意：Support_388945a0 帐户允许帮助和支持服务使用签名脚本进行交互操作，这个帐户主要用于控制从帮助和支持服务中访问的签名脚本。管理者可以使用这个账户为登陆到当前计算机上，却没有管理权限的普通用户，授予一定的权限， 允许其运行嵌入在帮助和支持服务中的签名脚本。这些脚本以Support_388945a0帐户凭证，而非当前登陆帐户凭证，在本地计算机上被编译（解释），从而执行特定的管理操作。当被委派的用户在帮助和支持服务中点击链接的时候，脚本将会在 Support_388945a0 帐户的安全上下文中执行。这个帐户仅能有限制的访问计算机，而且默认是被禁止的。
