微软调整累积更新命名规则，在IT管理员强烈反对后恢复显示年月信息，但仍不包含架构和版本号等关键信息。此调整可能影响用户获取完整更新信息的能力。

嗯，用户让我帮忙总结一篇文章的内容，控制在100字以内，而且不需要用“文章内容总结”或者“这篇文章”这样的开头。直接写描述就行。 首先，我得仔细阅读文章内容。文章主要讲的是Group Managed Service Accounts（GMSAs），这是Windows 2012引入的特性。GMSAs由AD管理密码，自动更新，减少了手动管理的麻烦。但这也带来了安全风险，因为如果有攻击者获得了访问密码的权限，就可能控制整个AD。 文章还提到了几个关键点：GMSA的密码由AD管理，计算机需要请求密码来启动服务，配置GMSA允许特定计算机访问密码。如果攻击者控制了这些计算机或有权请求密码的账户，GMSA就会被攻破。 然后是对象类和属性，比如msDS-GroupMSAMembership、msds-ManagedPassword等。这些属性定义了哪些主体可以访问密码以及密码的管理策略。 最后是实验室的例子，使用PowerShell脚本Get-ADServiceAccount来查找GMSAs，并展示了一个实际案例中GMSA被配置在Domain Admins组中，导致潜在的安全风险。 用户的需求是简明扼要地总结内容。我需要抓住主要点：GMSAs的功能、自动密码管理、潜在的安全风险、关键属性和实验室示例。 现在组织语言：控制在100字以内，直接描述内容。确保涵盖所有关键点而不遗漏重要信息。 可能的结构：介绍GMSAs及其优势→自动密码管理→安全风险→关键属性→实验室示例→结论中的安全建议。 这样就能在有限字数内全面概括文章内容了。 本文介绍了Group Managed Service Accounts（GMSAs）的功能与安全性。GMSAs由Active Directory管理密码并自动更新，但若攻击者获取访问权限或控制相关计算机，则可能导致AD被攻破。关键属性包括msDS-GroupMSAMembership和msds-ManagedPassword等。实验室示例展示了如何通过PowerShell查找和分析GMSAs，并强调了配置不当可能导致的安全风险。
