This is the Ctrl icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
This icon for control is a rectangle with sides that are nearly equal in length. The width is a bit larger than the height. The corners are rounded, and at its center are there letters ctrl, with the C being capitalized.
