May be you are right.

However every registry cleaner that I have used gives an option to back up the deleting that it does. Wise Registry Cleaner that I have never used, would have done the same. It should be quite simple to restore the the Registry back to its original shape.
I agree - the trick is to do it in the least damaging way, which is why I put the suggestions I made in the order I did.

The optimum solution is to use any internal restore functionality that the 'Cleaner' has - unfortunately, I haven't been able to test WiseFixer properly to find out what its capabilities are, so I can only hope that they do include some capability of that kind - especially when different versions of the program are involved.
There's also the possibility that the user has deleted the archive for some reason - either deliberately or accidentally.

Second-best is System Restore - which may also have been disabled by the 'Cleaner'.

Manual fixing is a poor third - because it can only address the obvious problem of the missing service, and not any other faults that the 'Cleaner' may have introduced.
