Oracle11g Express Edition SYSTEM schema is locked

Question

Recently I installed oracle 11g Express Edition in my windows 7 (64 bit) OS. I have set the password for SYSTEM schema while installing Oracle. I have tried to login SYSTEM schema. But I failed to login because of wrong password. Now the account is locked. I could not find the password as i didn't unlock any other schema.

Please help me to re-set or find the password.
