So I was going to start working earlier this morning. I started my computer as usual and at Windows login screen my keyboard stopped working. However, the keyboard did work after I entered into BIOS Setup, but as soon as Windows started loading the keyboard will stop working, even if I boot Windows into Safe Mode. After spending many frustrating hours to try the methods available on the net, I found this solution and it worked great!<\/p>\n

Note:<\/strong> I recommend you to create a backup of your registry or create a System Restore point before you proceed! If your keyboard also doesn’t work in BIOS Setup, it may be physically damaged.<\/em><\/p>\n

Get Around Windows Login Screen<\/strong><\/p>\n

To use this method, you should be able to access the Windows Registry in some way and change the registry keys. I managed to get into Windows by using a separate USB mouse and accessing the On-Screen Keyboard by which I could login and do the necessary registry changes. You can access the On-Screen Keyboard from Windows login screen:<\/p>\n

    \n
  1. On the log on screen in the bottom left-hand corner is an “Ease of Access” button, pictured below. Click on this button to access the Ease of Access panel on the log on screen.\n

    \"ease-of-access\"<\/p>\n<\/li>\n

  2. On this panel, check the box for “Type without the keyboard (On-Screen Keyboard)” and then click on Apply.\n

    \"on-screen-keyboard\"<\/p>\n<\/li>\n

  3. In about five seconds, the on-screen keyboard will pop up and you will be able to use it to enter your password on the log on screen.<\/li>\n<\/ol>\n

    If both your keyboard and mouse stop working, try to boot your computer from a WinPE or Linux Live CD, the keyboard or mouse might just work fine and you can then proceed to the next step for changing registry keys.<\/p>\n

    Manually Fix Corrupted Registry Key<\/strong><\/p>\n

    This problem may be caused by a Windows registry entry that has become corrupted. To use Registry Editor to fix the corrupted Registry entry, follow these steps:<\/p>\n

      \n
    1. Press the Windows logo key + R to open the Run dialog box. Type regedit<\/code> and press Enter to open the Registry Editor.<\/li>\n
    2. In the left panel, navigate to the following registry key:\n

      HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Class\\{4D36E96B-E325-11CE-BFC1-08002BE10318}<\/code>\n<\/li>\n

    3. In the right panel, you should now see a key UpperFilters<\/code> which should contain at least one entry “kbdclass”. If there are more entries out there, double-click on the UpperFilters key and delete other entries except “kbdclass” (without quotes).\n

      \"kbdclass\"<\/p>\n<\/li>\n

    4. Restart Windows, and the problem should be fixed.<\/li>\n<\/ol>\n

      The problem in my situation was that there was also a keyboard driver installed from VMware. The VMware Keyboard Driver had an additional entry “vmkbd” in the UpperFilters key, but as I discovered the driver file that was needed (C:\\Windows\\system32\\drivers\\vmkbd.sys) was missing which in effect caused all the problems. <\/p>\n

      I hope this trick will be helpful to others in the same predicament.<\/p>\n","protected":false},"excerpt":{"rendered":"
