for example I want to change factoryUicontrolFontSize with this command;
set(groot,'factoryUicontrolFontSize',10)
When I execute above command, I got;
Error using set Factory properties can only be queried, not set.

The whole point of factory settings is that they cannot be changed: this allows a system to be rest to its initial (working) state. If any user could simply play around and change the factory settings, then a true reset would never be possible.
Try adjusting the default values instead of the factory values.

You can't change the factory settings -- they are set at the "factory" (here at MathWorks.)
You can set the DEFAULT settings instead -- change the 'factory' part of your command to 'default' instead. Note that this will only change future uicontrols; it will have no effect on uicontrols that already exist, even if you didn't give them a different FontSize (and so they were using the default from when they were created.)

But msgbox() and other UI objects don't read the default values of properties, they read the factory value. On my computer, that results in very small print. And when the font size is modified (along with the box extent) after msgbox is called, on slower systems you then see the box changing - a rather ugly effect.

I have the same problem. I end up just overwriting inputdlg, questdlg, etc but it would be nice if there was a way to just increase the FactoryUicontrolFontSize.
