Hi Philip,

Yes, I do think that would solve the problem, but I would recommend
limiting it to 64 KB which is Microsoft's recommendation per software
product. This keeps the registry small and prevents anyone from
heavily abusing it. After all, 100 values is quite a lot, and I can't
imagine any game requiring that many values for program settings etc.
I hope you stressed that saved games should be serialized and written
to a file not stored in the registry. As long as people do that 100
values isn't necessary for program settings, registration info, etc.
