Windows 11 二月更新可能导致部分三星笔记本电脑用户无法访问 C 盘
#Bug
微软正在调查一个影响部分三星笔记本电脑的问题。这些用户在安装 2026 年 2 月安全更新后无法访问 C 盘，无法启动应用。微软表示正与三星合作以确定该问题是否与 Windows 更新或受影响设备上安装的三星软件有关。微软称，受影响用户会遭遇 C 盘无法访问，访问被拒绝的错误信息。该问题也阻止用户访问文件，启动 Outlook、Office、浏览器、系统工具和快速助手（Quick Assist）。问题主要发生在巴西、葡萄牙、韩国和印度，影响三星 Galaxy Book 4 等消费类设备。该问题可能与三星共享应用有关，但确切原因尚未确认。

💀«Durov has died», «you will be killed tomorrow», «message not delivered», «access to the server has been completely terminated» — these scary messages were sent from the official Telegram account? These messages have been spreading since the launch of the Guest Mode functionality for bots. The most interesting thing is that the bot guest mode works not only in groups, but also in personal messages. And +42777 (and other support accounts) are also PMs.
🤖 At first, there was a #bug where forwarding messages from a PM sent by a bot with guest mode was attributed to your interlocutor — not a bot. You can imagine that a guy created his own bot where by writing " @yourbot" (without quotes) he sent a certain word specified in the script. 🔹 Now guest mode does not work in support, and the bug has been fixed — the authorship of forwarded messages is assigned correctly.
