2020-10 Cumulative Update Preview for Windows 10 Version 1909 (KB4580386).2020-07 Cumulative Update Preview for Windows 10 Version 2004 (KB4568831).To give customers more control, we've enabled a workaround that involves changing a registry key value, available with the following Windows Updates: We've since received feedback that some customers, especially those with multiple physical monitors, would prefer to disable this virtual monitor pre-allocation.
Because of that feedback, alongside increased usage of Win32 applications, we decided to pre-allocate three virtual monitors during startup of Windows Mixed Reality to prevent this disruption and enable customers to launch up to three concurrent Win32 applications without experiencing the headset display freeze. Customers offered feedback that the experience was uncomfortable and disruptive. Unfortunately, creating a virtual monitor is an intensive task that can cause the headset display to briefly freeze. Each time a new Win32 application is launched, another virtual monitor has to be created. To enable this support, a virtual monitor must be created to host the Win32 application. Support for classic Win32 applications in Windows Mixed Reality was introduced with the Windows Update. Some customers, especially those with more than one physical monitor, may notice issues with desktop layout and input handling as a result. General improvements to keyboard launch and visuals.Īfter taking the 2020-01 Cumulative update for Windows 10 Version 1903 or later, virtual monitors will appear as generic physical monitors in Settings > System > Display during Windows Mixed Reality sessions.The WebVR Showcase app is present in the mixed reality home, despite WebVR no longer being supported.Selecting a hyperlink in the mixed reality home launches a web browser on the desktop instead of the mixed reality home.Attempting to activate those windows launches Edge in the Desktop app. Windows from the previous Microsoft Edge are still placed around the mixed reality home, but cannot be used.
