Nwiz.exe – What Is It And How To Remove It From Startup

Purpose of nwiz.exe

The nwiz.exe (Nvidia nView Wizard) process is associated with the newer versions of the Nvidia graphics card drivers (2002 onward). Nvidia nView Wizard allows users to improve and customize desktop layouts by providing a range of options, including the option to have up to 32 virtual desktops, split the display across more than one monitor, have a desktop that is larger than the viewable area of the monitor, add transparency to applications windows, zoom portions of the display, and much more.

The nwiz.exe file is installed on your PC along with Nvidia graphics video cards. The purpose of nwiz.exe is to reinstall the special features of your Nvidia graphics card automatically when you boot your system. If you do not use any special features, such as the ones mentioned above, the nwiz.exe process terminates, otherwise it stays in the background.
