How can I change the file with wzcsvc.dll file is 5.1.2600.2180
Is there other files that also needs to be changed?

Sorry I couldn't find your part 1... anyway, the WZC consists of several files
and you install all of them together as one of recent MS updates:
kb 893357
kb 918997

These patches may also repair the WZC service startup and registry settings,
however I haven't tested this. Of course, if some 3rd party app keeps
fighting with WZC over your wireless card, it is a different issue.
