How to read Private Key form Windows Key Store?

Question

Is it possible to read valid private key from windows keystore like Windows-MY, Windows-ROOT in java? I can read private key from other storages eg: pkcs12 (.pfx, .p12), pkcs11, jks(.jks), jceks . I have tried something like this but which works fine for the other keystores but Windows-MY and Windows-ROOT return invalid and not-null Private key.

NB: here, private key and public key in chains is a valid key-pair.

final char[] keyPass = "test1234".toCharArray();
X509Certificate[] chains=......;

KeyStore sourceKeyStore = KeyStore.getInstance("Windows-MY");
sourceKeyStore.load("null", keyPass);

Enumeration<String> sAliases = sourceKeyStore.aliases();
while (sAliases.hasMoreElements()) {
    String alias = sAliases.nextElement();
    Key privKey = sourceKeyStore.getKey("testName", keyPass); // privKey is not null here but misses some information

    sourceKeyStore.setKeyEntry("testName", privKey, keyPass, chains); //gives Key protection algorithm not found error
}
