How to screen shot a UAC prompt?
提问by Adrian McCarthy
I'm trying to document a work flow with a series of screen shots. At one point in the flow, a UAC prompt appears, and I'd like to grab a bitmap of it to make my storyboard complete. Because UAC prompts are on a virtual desktop (or something like that), the usual Alt+PrintScreen doesn't work. Any suggestions?
我正在尝试使用一系列屏幕截图来记录工作流程。在流程中的某个时刻，会出现一个 UAC 提示，我想获取它的位图以完成我的故事板。因为 UAC 提示在虚拟桌面（或类似的东西）上，所以通常的 Alt+PrintScreen 不起作用。有什么建议？

This method using the group policy editor should do the job:
这种使用组策略编辑器的方法应该可以完成这项工作：
1) Run gpedit.msc
2) Under Computer Configuration\Windows Settings\Security Settings\Local Policies\SecurityOptions:Change “User Account Control: Switch to the secure desktop when prompting for elevation” to disabled
1) 运行 gpedit.msc
2) 在计算机配置\Windows 设置\安全设置\本地策略\安全选项下：将“用户帐户控制：提示提升时切换到安全桌面”更改为禁用
Undo this change after the screenshot, because it makes the system less secure!
截屏后撤消此更改，因为它会降低系统的安全性！

Change your UAC settings to disable the secure desktop, and then you can take the screenshot. In Windows 7, this is one of the options on the UAC slider, in Vista, I believe you need to configure the Security Policy.
更改您的 UAC 设置以禁用安全桌面，然后您可以截取屏幕截图。在 Windows 7 中，这是 UAC 滑块上的选项之一，在 Vista 中，我相信您需要配置安全策略。
Alternatively, run Windows in a VM and take a screenshot of that.
或者，在 VM 中运行 Windows 并截取它的屏幕截图。

You can also remote desktop to the Windows 7 machine and run the screenshotter (or video capture) on the other machine. I've used this very successfully.
您还可以远程桌面到 Windows 7 机器并在另一台机器上运行屏幕截图器（或视频捕获）。我已经非常成功地使用了这个。
