工程师分析 Win11 争议后台服务：用于性能诊断，含 84 个诊断脚本_我的网站

A |      8 月 26 日消息，逆向工程师 Xusheng Li 于 8 月 15 日发布博文，深度分析了 Windows Health and Optimized Experiences 服务。曾于 8 月 3 日报道，微软为 Win11 系统新增上述后台服务，网友反馈该服务会在电脑每次开机时自启动，持续监控 CPU 使用率、温度和电池情况，并每隔 15 分钟将数据发给微软。微软副总裁斯科特 · 汉塞尔曼回应表示该功能上线于 2025 年，用途主要是采集性能诊断数据。逆向工程师 Xusheng Li 逆向该服务的 whesvc，其结果基本印证了微软的说明，但也发现其底层架构比普通性能诊断工具复杂得多。    The Biden administration is drafting a $100 billion foreign aid package that includes assistance for Israel as well as other top security priorities, according to two people familiar with the details.Details on the spending request were still being finalized ahead of an official request sent by the White House to Congress this week.One person told ABC News that the “bulk” of the assistance will likely go toward Ukraine, while others also said that it included $10 billion for Israel. The officials spoke on condition of anonymity in order to discuss details that hadn't been announced yet by the White House.The request comes as President Joe Biden travels to Israel in a show of unity with the Jewish state following the brutal Oct. 7 attack on civilians by Hamas terrorists from Gaza.On Capitol Hill, Senate leaders suggested Tuesday that such a sweeping aid package would find support among lawmakers."We'd like to get the supplemental package moved as quickly as possible because the needs are great in both Israel and Ukraine," said Senate Democratic Leader Chuck Schumer of New York.Republican Leader Mitch McConnell said he would support bundling aid for Ukraine and Israel and that he expects the administration to include money for border security, too."The border part of it needs to be credible, not just some reference to it but a credible deal," he told reporters.Bloomberg was first to report the $100 billion total.The aid proposal for Israel follows extensive discussions between the two countries, with Israel appearing to opt -- at least for now -- against a massive ground invasion of Gaza, even as international groups accuse Israel of worsening a humanitarian crisis by not allowing food or water into Gaza and cutting off electricity.Behind closed doors, Biden officials have grown deeply worried about hardliners within Israel pushing for a scorched-earth military response that wouldn't do enough to prevent civilian casualties, according to a senior administration official who spoke on condition of anonymity. At one point this week, aides believed that only the president himself could convince officials there that allowing humanitarian aid in Gaza would be in their country’s best security interests.When asked about those discussions, White House National Security Council spokesman John Kirby said they’re not telling the Israeli military how to operate and that civilians should be protected. At the same time, following the law of war is critical and something Biden has pressed Israel on, he said.“Since almost the very, very beginning here, we have been talking about how important it is for democracies, like Israel and the United States, to stand up for the law of war, to respect innocent civilian life, unlike Hamas. So this is a foundational element of the discussions that we've had with the Israelis for forever, and we'll continue to do that going forward," Kirby told ABC's "Good Morning America."Following lengthy meetings earlier this week between Secretary of State Antony Blinken and his Israeli counterpart, the two allies seemed to have reached some kind of consensus. Details of the aid package are now circulating among U.S. officials as Biden is en route to the region.Budget experts say Israel’s assistance needs aren’t likely to be urgent due to a 2016 agreement that provides Israel $3.8 billion a year over 10 years. More pressing, they say, is Ukraine, which has run out of long-term funding as it seeks to fend off Russia.Some House Republicans have questioned the need for more U.S. aid to Ukraine. By tying Ukraine and Israeli aid in a single legislative package, the White House would make it harder for GOP hardliners -- who are staunch allies of Israel -- to reject it.Pro-Israeli groups have also called on Biden to include at least $500 million in grant funding for Jewish communities in the U.S. to protect synagogues and other community sites due to threats. It was not immediately clear if that request was part of Biden’s aid package as of Tuesday.ABC's Chief Global Affairs Correspondent Martha Raddatz and ABC reporters Justin Gomez and Shannon Crawford contributed to this report.。

B | whesvc 服务的核心功能位于 windiag.dll（229 KB），该动态链接库内嵌 Lua 5.4.7 脚本语言。微软还提供 whesvc_assets.dll，其中包含 84 个已编译 Lua 脚本，用于处理不同诊断场景。脚本引擎公开了 79 个原生函数，可访问 Windows 的多类系统能力。该服务可以读取和修改 Windows 注册表，执行文件操作，创建并交互进程，查询 WMI（Windows 管理规范），收集 ETW（Windows 事件跟踪）记录，检查安全令牌，获取电源和温度信息，下载符号文件，创建 .cab 文件，并发起 HTTP 请求。服务还提供通用 FFI（外部函数接口），允许脚本调用原生动态链接库，并操作多种 Windows 句柄。不过，Li 没有发现微软利用这些能力随机修改文件或注册表，现有脚本主要执行常规诊断任务。这些脚本可以在应用停止响应后采集跟踪记录，监控输入延迟和显示异常，识别启动缓慢的应用，并检测长期处于挂起状态的服务。电源相关模块能够调查电池异常耗电，判断阻止电脑进入睡眠状态的原因，并响应持续的高功耗行为。memory_handle_leak 模块会在多个时间间隔内跟踪内存和句柄数量，再结合连续增长情况与线性回归斜率，区分潜在内存泄漏和正常增长。system_summary 模块会生成 900 秒、即 15 分钟的 JSON 摘要，但文件保存在本地。

C | 尽管服务具备网络功能，Li 没有找到任何会实际发起任意 HTTP 请求的场景。相关阅读：。
