How to change the username in the processes tab in windows task manager

[m8rvil]

I noticed that my username in the processes tab in windows task manager has been changed by either malware or a windows update. It now appears in Taiwanese or Chinese! How do I change it back? I have googled this topic with no success. I am running Windows 7 Ultimate. I have scanned for malware with MalwareBytes, AVG 2012 and found no malware or spyware.

I just wanted to know,is just appearing as Taiwanese or Chinese in the windows task manager or it has affected the user account as well??? I mean are you having any issues in logging in with the same account?

It only appears in windows task manager. My user account has not been affected. I attached two files so that you can see what it looks like.
