I want to increase icons and texts
icons and texts of Toolbar, Table of Contents and Search window is very small!!!
But, Texts in menu-bar is proper size. I don't understand this situation
Now, I use window 10 and arcmap 10.1
The easy one to fix is the icon size for the buttons on your toolbars.
Use the Main Menu to find Options tab on the Customize | Customize Mode dialog, and tick the Large icons checkbox.
Increasing font size is messier but explained well at https://gis.stackexchange.com/a/31347/115
