Oracle XE listener issue fixing when changing Windows 10 system/computer name

Change the host name with your computer name or localhost in below two files
listener.ora and
tnsnames.ora

Navigation path to the files :
C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN

Now, from the windows services, restart OracleXETNSListener and try connecting to XE SID as shown in below image.

Username : sys , Password : tiger (that is given at the time of installation)

Default password is : sysdba for sys user to connect to xe




The reason for changing host name in my case : 
Recently, I have changed the windows 10  system name and from that point of time, I didn't start oracle db in local but today when I started the oracle db and the listener, the connection for xe SID with sys/tiger credentials not worked.
