# Enable the Block at First Sight feature in Windows 10 # Block at First Sight
**Applies to** **Applies to**
- Windows 10, version 1607 - Windows 10, version 1607
**Audience**
- Network administrators
Block at First Sight is a feature of Windows Defender cloud protection that provides a way to detect and block new malware within seconds. Block at First Sight is a feature of Windows Defender cloud protection that provides a way to detect and block new malware within seconds.
You can enable Block at First Sight with Group Policy or individually on endpoints. It is enabled by default when certain pre-requisite settings are also enabled. In most cases, these pre-requisite settings are also enabled by default, so the feature is running without any intervention.
## Backend processing and near-instant determinations ## How it works
When a Windows Defender client encounters a suspicious but previously undetected file, it queries our cloud protection backend. The cloud backend will apply heuristics, machine learning, and automated analysis of the file to determine the files as malicious or clean. When a Windows Defender client encounters a suspicious but undetected file, it queries our cloud protection backend. The cloud backend will apply heuristics, machine learning, and automated analysis of the file to determine the files as malicious or clean.
If the cloud backend is unable to make a determination, a copy of the file is requested for additional processing and analysis in the cloud. If the cloud backend is unable to make a determination, the file will be locked by Windows Defender while a copy is uploaded to the cloud. Only after the cloud has received the file will Windows Defender release the lock and let the file run. The cloud will perform additional analysis to reach a determination, blocking all future encounters of that file.
If the Block at First Sight feature is enabled on the client, the file will be locked by Windows Defender while a copy is uploaded to the cloud, processed, and a verdict returned to the client. Only after a determination is returned from the cloud will Windows Defender release the lock and let the file run. In many cases this process can reduce the response time to new malware from hours to seconds.
The file-based determination typically takes 1 to 4 seconds.
> [!NOTE] > [!NOTE]
> Suspicious file downloads requiring additional backend processing to reach a determination will be locked by Windows Defender on the first machine where the file is encountered, until it is finished uploading to the backend. Users will see a longer "Running security scan" message in the browser while the file is being uploaded. This might result in what appear to be slower download times for some files. > Suspicious file downloads requiring additional backend processing to reach a determination will be locked by Windows Defender on the first machine where the file is encountered, until it is finished uploading to the backend.

## Enable Block at First Sight ## Confirm Block at First Sight is enabled
### Use Group Policy to configure Block at First Sight Block at First Sight requires a number of Group Policy settings to be configured correctly or it will not work. Usually, these settings are already enabled in most default Windows Defender deployments in enterprise networks.
You can use Group Policy to control whether Windows Defender will continue to lock a suspicious file until it is uploaded to the backend. > [!IMPORTANT]
> There is no specific individual setting in System Center Configuration Manager to enable Block at First Sight. It is enabled by default when the pre-requisite settings are configured correctly.
This feature ensures the device checks in real time with the Microsoft Active Protection Service (MAPS) before allowing certain content to be run or accessed. If this feature is disabled, the check will not occur, which will lower the protection state of the device. ### Confirm Block at First Sight is enabled with Group Policy
Block at First Sight requires a number of Group Policy settings to be configured correctly or it will not work.
**Configure pre-requisite cloud protection Group Policy settings:**
1. On your Group Policy management machine, open the [Group Policy Management Console](https://technet.microsoft.com/library/cc731212.aspx), right-click the Group Policy Object you want to configure and click **Edit**. 1.
