Windows mixed reality error code 1-4

Hi rediadan

My name is Andre Da Costa; an Independent Consultant, Windows Insider MVP and Windows & Devices for IT MVP. I'm here to help you with your problem.

First, try restarting your graphics driver:
Press Windows key + Ctrl + Shift + B

If that does not work...

Press Windows key + X
Click Device Manager
Expand Display adapters
Right click the current display adapter
Click Properties
Click Driver tab
Click Rollback driver if the option is available

If not
Right click the current display adapter
Click Uninstall
Check the box that says, "Delete the driver software for this device.”
Exit Device Manager
Restart

Go to Start -> Settings -> Update & security, then Check for updates and install any available updates.

You might need to update the display driver from the manufacturer of your computers website.

If you have an nVidia, AMD ATI video card or Intel HD graphics installed, you can download the latest drivers from their website.

First, determine what type of graphics you have installed.

Press Windows key + X
Click Device Manager
Expand Display adapters

Once you have determined the graphics driver, go the vendors website and search for the driver in the download section:

Intel - Downloads for Graphics Drivers - Drivers & Software - Intel
https://downloadcenter.intel.com/product/80939/...

nVidia - http://www.nvidia.com/Download/index.aspx

AMD ATI - Download Drivers - AMD Support
http://support.amd.com/en-us/download

Some of these sites offer autodetect options.

Check if it works.
