Singleton Implementation Issue

Tech-Archive recommends: Fix windows errors by optimizing your registry

Unless I'm misunderstanding the pattern and it's various implementations,
Singleton effectively makes the constructor unavailable to clients. The
constructor for any given class, however, is what we otherwise use [outside
of Singleton implementations] to *require* specific parameters be supplied
upon instantiation (provided of course that we've removed the default
constructor).

So my question: I want to have a Singleton implementation that requires
specific parameters to be supplied upon instantiation.

My initial shot at a reasonable answer (please provide your thoughts on
this):
1. I'll go with one of the Singleton implementations that results in lazy
instantiation.
2. Then, in order to *require* the parameters to be supplied, I'll have a
*method* named Instance() instead of a *property* of that name. The method
then defines the arguments for which clients are to supply the parameter
values upon accessing the Singleton.

Thoughts? Considerations? Perspective?

Thanks.
