Oracle11g Express Edition schema locked

Question

I recently installed oracle 11g Express Edition on my Windows 7 (64-bit) OS. I set a password for the SYSTEM schema when installing Oracle. I tried to enter the SYSTEM system diagram. But I was not able to log in due to an incorrect password. The account is now locked. I could not find the password since I did not open another scheme.

Please help me reset or find the password.
