Edit sysoc.inf located in C:\WINNT\inf\
Find the line that reads as follows:
AccessOpt=ocgen.dll,OcEntry,optional.inf,HIDE,7
Delete the 'HIDE' so it reads:
AccessOpt=ocgen.dll,OcEntry,optional.inf,,7
Open Control Panel -> Add/Remove Programs -> Add/Remove Windows Components -> Accessories and Utilities -> Details -> Uncheck Accessibility Wizard -> OK
Hope that helps.
