Had this problem recently converting a Win 8 x64 laptop install using VMWare converter 5.1, only difference was I had extra settings in the keyboard registry section (mouse section was clear and mouse worked ok):
Key in this case was:
SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318}
UpperFilters:REG_MULTI_SZ: had mutliple entries as above, removed all but "kbdclass" and rebooted.
Thanks for the tip!
Cheers
Benni
