WInXP half working mouse and keyboard, no input after Vmware driver removal

[ruthan]

Hi,
i have strange problem.  I found out that i have some Vmware leftovers -vmkbd.sys , problem is when i remove it, i cant log into machine, but i had other issues.

  Setup Win XP SP3 with PS/2 mouse + keyboard and USB mouse + keyboard - all wired, 4 devices.

  Problem is when i remove Vmware driver - on logon screen only PS/2 mouse is working, until i press PS/2 keyboard key, after that it freeze.
  With Vmware driver installed, all PS/2 devices are working + USB keyboard is working, USB mouse is not working for some reason.
  Other issue is thas control panel - keyboard and mouse are not just starting, any other panels are ok, no input freezes within session etc, so its software problem.  

  I tried other clean XP install, same USB drivers, no Vmware and all devices are working fine. When i moved machine to Vmware for test, i had only keyboard, no mouse until Vmware tools installed - i dont thing that is normal behavior.

   Any ideas, what could be wrong and how to solve it?

Open the following key in registry:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}

Remove vmkbd from UpperFilters

 How extractly?
 I see some parent key like:
 {4D36E96B-E325-11CE-BFC1-08002BE10318}
 Should i just remove whole parent key, or just UpperFilters with value item?

modify UpperFilters, remove only vmkbd inside

Sorry, but on more claricifation. Only modify and let it blank (no value) or remove whole UpperFilters item?
