Struggling with e-mail systems

As a perfectionist, I have been struggling to have a perfect PIM (personal information management) solution. For the personal part, I currently use (Exchange-based) Outlook.com. For the professional (institutional) part, things have been so hard. This entry records some of the problems I have encountered so far, and for certain ones, a solution.

Windows 10 自动更新重启的观察

我之前在知乎问题“为什么很多人要禁止 Windows 10 自动更新”下多个回答的评论区宣传 ShutdownBlockReasonCreate 这个 API,尝试“教育”开发者正确处(阻)理(止)Windows 10 自动更新重启带来的关键任务被终止的问题,还因为这个被人挂了。一开始我抱着怀疑的态度提出的方法,之后不知什么原因就假设这个 API 确实有效了——我当时已经知道该 API 不能其效果的情况,但是我没料到“大更新”的时候 Windows 真的会用那么暴力的方法重启电脑。本文记录了一些我的观察,并从使用者的角度给出一些关于 Windows 10 自动更新处理上的建议。
