问题

超级用户阅读器gate\u engineer想知道Windows中“shutdown/r”和“shutdown/g”的区别是什么：

I was reading through some of the opti*** for the shutdown command in Windows when I stumbled across the following option descripti***:

I thought that when Windows restarts, every application would be closed during the shutdown process, then started again after the system boots. Some possibilities that come to mind are:

• A holdover from previous versi*** of Windows that performed some type of restart trickery
• A temporary override of the system configuration’s default behavior

Is it either of these or something completely different?

Windows中的“shutdown/r”和“shutdown/g”有什么区别？

答案

超级用户贡献者DavidPostill为我们提供了答案：

What is “shutdown /g”?

The /g option will restart applicati*** that are registered for restart with the RegisterApplicationRestart API.

The Windows Restart Manager (introduced in Windows Vista) supports gracefully shutting down and restarting applicati*** that registered for restart with the RegisterApplicationRestart API.

This functionality is used by Windows Update. Thanks to the Restart Manager, when I show up to my desktop computer yawning in the morning (even following a system restart), I have my Outlook, browser, OneNote, Visual Studio, and messenger applicati*** all lined up as they were when I went to bed.

Suppose that you want to initiate “automagically restarting” everything after a restart. As of a few weeks ago, I thought it was necessary to write a **all application that uses the Restart Manager APIs (i.e. RmStartSession and RmShutdown) to do this. And then it hit me that the shutdown command must already have support for doing this. And indeed, it has:

• shutdown /g
