The Windows 10 Start Menu is a redesign of the original Start Menu. It is not the Start Menu which we are used to seeing in Windows 7. It includes live tiles from the Start screen and eliminates the useful system and personal folders which used to be 1-click away. The Start Menu may look a bit cluttered out-of-the-box to some users. If you are not happy with its default look, here is good news for you - you can customize and tweak it by removing all the unnecessary items easily. Follow this tutorial to make Windows 10 Start menu look like Windows 7 Start menu.
Ever since Windows 8 got released, Classic Shell saw a massive boost in popularity as the most premier yet free Start Menu replacement. For those who don't know, Classic Shell is a free project with the goal to restore removed features in Windows - those features whose loss made Windows usability and productivity worse. Classic Shell began in the Windows 7 era (yes you read that right!), it existed much earlier than Windows 8.
