FAQ
,=== The Windows Logon Screen, Shutdown, UAC Dialogs, Ctrl+Alt+Del, LockScreen do not work. ===
These screens are on the "Secure Desktop", Microsoft has intentionally limited access to capture this screen to prevent malware attempting to capture information from these screens that might be sensitive. There is little we can do here unless Microsoft are is willing to let us sign the host application as an 'Accessibility' program.` The workaround for this issue is to turn down the security level in the `User Account Control Settings` dialog as shown here: [[Image:Uac.png]]
Users of NVIDIA cards that support the NVidia Capture API (Quadro, Tesla, etc) will find this limitation only applies to the Windows Logon Screen and Shutdown Screens, the NvFBC capture API is able to capture the "Secure Desktop" outside of Microsoft's control.
