You've already specified the switches in the command definition , so 
your service definition should read something like:

define service{
         use                           generic-service
         host_name                 Windows_1
         service_description     C:\ Drive Space
         check_command        check_nt_disks!USEDDISKSPACE!90!95
  }

You've also hardcoded the drive letter in your command definition, but 
left the type of check as a variable.  Since check_nt_disks will always 
be running USEDDISKSPACE, it should really look like:

define command {
         command_name    check_nt_disks
         command_line    /usr/lib/nagios/plugins/check_nt -H 
'$HOSTADDRESS$' -p 12489  -v USEDDISKSPACE -l '$ARG1$' -w '$ARG2$' -c 
'$ARG3$'
}

with a service definition of:

define service{
         use                           generic-service
         host_name                 Windows_1
         service_description     C:\ Drive Space
         check_command        check_nt_disks!C!90!95
  }
