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?
This method using the group policy editor should do the job:
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
Undo this change after the screenshot, because it makes the system less secure!
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.
Alternatively, run Windows in a VM and take a screenshot of that.
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.
