Why Did the My Computer Icon Disappear?
Beginning with Windows XP, Microsoft added a link to My Computer in the Start Menu.

In an effort to declutter the desktop, Microsoft chose to remove the My Computer icon beginning with Microsoft Windows Vista. Along with this change, Microsoft also dropped the “My” from “My Computer,” changing it to “Computer.”
