+# Enable or block Windows Mixed Reality apps in the enterprise
+
+**Applies to**
+
+- Windows 10
+
+Windows 10, version 1709 (also known as the Fall Creators Update), introduces [Windows Mixed Reality](https://blogs.windows.com/windowsexperience/2017/10/03/the-era-of-windows-mixed-reality-begins-october-17/). Organizations that use Windows Server Update Services (WSUS) must take action to [enable Windows Mixed Reality](#enable). Any organization that wants to prohibit use of Windows Mixed Reality can [block the installation of the Mixed Reality Portal](#block).
+
+
+
+## Enable Windows Mixed Reality in WSUS
+
+To enable users to download the Windows Mixed Reality software, enterprises using WSUS can approve Windows Mixed Reality package by unblocking the following KBs:
+
+- KB4016509
+- KB3180030
+- KB3197985
+
+Enterprises will not be able to install Windows Mixed Reality Feature on Demand (FOD) directly from WSUS. Instead, use one of the following options to install Windows Mixed Reality software:
+
+- Manually install the Mixed Reality software
+- IT admin can create [Side by side feature store (shared folder)](https://technet.microsoft.com/library/jj127275.aspx)
+
+
+
+## Block the Mixed Reality Portal
+
+You can use the [AppLocker configuration service provider (CSP)](https://docs.microsoft.com/windows/client-management/mdm/applocker-csp) to block the Mixed Reality software.
+
+In the following example, the **Id** can be any generated GUID and the **Name** can be any name you choose. Note that `BinaryName="*"` allows you to block any app executable in the Mixed Reality Portal package. **Binary/VersionRange**, as shown in the example, will block all versions of the Mixed Reality Portal app.
