Fix : Keyboard Mouse not working after login in Windows 8 , windows 7 , Vista & XP

This post will help you fix / troubleshoot an issue with your Windows PC, where, after login or at welcome screen your keyboard and mouse stops working. This can happen with either a USB interface keyboard / mouse or even with a PS2 Keyboard and mouse. Do remember that your keyboard will work in your BIOS & both your keyboard / mouse will work with a Live CD too. In some cases your Keyboard and mouse will start to work in Safe Mode.

The Methods mentioned herein are based on both the scenarios where your keyboard & mouse will or won’t work in safe mode

Method 1

  • Sometime a LAN ( Network connection ) can be a culprit for this problem
  • Disconnect your LAN ( network wire ) from your computer
  • Start your computer
  • Check if your keyboard /mouse are working
  • If yes,
  • Go to Command Prompt ( with administrator privileges )
