| 11 | +# FailedToTakeScreenshot error during computer use action |
| 12 | + |
| 13 | +This article provides troubleshooting guidance for "FailedToTakeScreenshot" errors that occur during [computer use actions](/microsoft-copilot-studio/computer-use) for Copilot Studio agents. The computer use model requires screenshots to interact with the desktop. If capturing a screenshot fails, a "FailedToTakeScreenshot" error is given and the computer use action ends. |
| 14 | + |
| 15 | +## Symptoms |
| 16 | + |
| 17 | +During a computer use action a "FailedToTakeScreenshot" error occurs and the action ends in failure. |
| 18 | + |
| 19 | +## Cause 1: a UAC prompt is displayed |
| 20 | + |
| 21 | +If Windows displays a [User Account Control](/windows/security/application-security/application-control/user-account-control/) (UAC) prompt, the desktop is blocked by the prompt and capturing the screen fails. |
| 22 | + |
| 23 | +### Solution |
| 24 | + |
| 25 | +- Ensure that a UAC prompt isn't displayed when you open a new Remote Desktop session to the machine. |
| 26 | +- Verify that the [UAC level](https://support.microsoft.com/windows/user-account-control-settings-d5b2046b-dcb8-54eb-f732-059f321afe18) isn't set to **Always notify** as that can cause UAC prompts to be displayed during session startup. |
| 27 | + |
| 28 | +## Cause 2: the Windows OOBE experience is displayed |
| 29 | + |
| 30 | +The first time a user logs into the machine, Windows displays the [Out Of Box Experience](/windows-hardware/customize/desktop/customize-oobe-in-windows-11) (OOBE). This experience usually starts by displaying the message "Getting things ready". If the OOBE is displayed during the computer use action, capturing the screen fails. |
| 31 | + |
| 32 | +### Solution |
| 33 | + |
| 34 | +The OOBE is only displayed the first time a new user logs into the machine. Make sure to manually log the user into the machine at least once before using computer use actions. |
| 35 | + |
| 36 | +## Cause 3: the Remote Desktop session isn't displayed |
| 37 | + |
| 38 | +Capturing the screen fails if the Remote Desktop session isn't displayed. This can occur in the following cases: |
| 39 | + |
| 40 | +- When using an existing Remote Desktop session in the browser (for example connecting to a Power Automate Hosted machine), screen capturing fails if the Remote Desktop tab is not focused. |
| 41 | +- When using a Remote Desktop session in the [Windows Application](/windows-app/overview), screen capturing fails if the application window is minimized. |
| 42 | + |
| 43 | +### Solution |
| 44 | + |
| 45 | +Before starting a compute use action, ensure that the Remote Desktop session is focused and visible on the screen. |
