I think that it is a good idea to implement a good entropy source from
something like <wincrypt.h>.
I belive that it goes something like this (by looking briefly at the
platform SDK help).
HCRYPTPROV hCryptProv;
BYTE pbData[8];
CryptAcquireContext(
&hCryptProv,
NULL,
NULL,
PROV_RSA_FULL,
CRYPT_VERIFYCONTEXT);
CryptGenRandom(hCryptProv, sizeof(pbData), pbData);
