I'm using MATLAB version 2018b with the Image Processing Toolbox. I've run into the following error recently after not having a problem with it before. Having recently upgraded to Windows 10 I've made sure my graphics drivers are all up to date.
As soon as I open MATLAB
Warning: MATLAB previously crashed due to a low-level graphics error. To
prevent another crash in this session, MATLAB is using software OpenGL instead
of using your graphics hardware. To save this setting for future sessions, use
the opengl('save', 'software') command. For more information, see Resolving
Low-Level Graphics Issues.
When I opened Volume Viewer feature of the Image Processing Toolbox
Error using images.internal.app.volview.checkOpenGLDrivers
Windows Software OpenGL support does not meet the minimum requirement of this app. Try executing the command "opengl hardware". Type
"doc opengl" for more information.
Error in images.internal.app.volview.VolumeViewer
Error in volumeViewer (line 28)
images.internal.app.volview.VolumeViewer();
This happens each time I open MATLAB, additionally I did not save the "opengl" setting. Any help is appreciated thanks.

You can work around many graphics issues by using the software version of OpenGL® built-into MATLAB instead of using your graphics hardware. In some cases, MATLAB automatically switches to software OpenGL, for example, if it detects known issues such as outdated drivers or graphics virtualization. Software OpenGL does not support some graphics features, such as graphics smoothing.
To determine if you are using hardware or software OpenGL, type 'opengl info'. The returned information contains the line Software: 'false' if you are using hardware OpenGL or Software: 'true' if you are using software OpenGL.
To switch from hardware to software OpenGL, start MATLAB from the command prompt or terminal on your system using this command:
matlab -softwareopengl
To set your preferences so that MATLAB always starts with software OpenGL on this computer, execute this command at the MATLAB command line:
opengl('save','software')
These commands work only on Windows® and Linux® systems. Macintosh systems do not support software OpenGL. For more information about switching between hardware and software OpenGL, see the documentation for <http://www.mathworks.com/help/matlab/ref/opengl.html opengl> and the Renderer property for figures.
For the best results with graphics, use graphics hardware that is compliant with OpenGL 2.1 or later. For more information about the graphics features that different versions of OpenGL support, see System Requirements for Graphics.
Graphics hardware vendors frequently provide updated graphics drivers that improve hardware performance. To help ensure that your graphics hardware works with MATLAB, upgrade your graphics drivers to the latest versions available.
Check your computer manufacturer website for driver updates, for example, Dell® or HP®. If no updates are provided, then check your graphics hardware vendor website, such as one of the vendors listed here. To determine your vendor, type opengl info and check the Vendor field.
Alternatively, you may be able to check your driver vendor and versions outside of MATLAB. On Windows systems, enter dxdiag into the Command Prompt, and look at the "Display" tab. Certain Linux distributions will allow you to use glxinfo in the Terminal to see OpenGL and driver information.
If you saved a setting to always start MATLAB with software OpenGL, then after updating your drivers, you can revert that setting by executing:
opengl('save','hardware')
Then restart MATLAB.
If you cannot resolve the issues using the options described here, then you might have encountered a bug in MATLAB. Please contact MathWorks Technical Support and provide the following information:
