Change 'System Account' to logged in 'User Name'.

Sometimes in SharePoint 2010, we come across a situation where, instead of showing the user name of logged in, the site is displayed as 'System Account'.

Here are the steps to change it:

Step 1:

Open 'SharePoint 2010 Central Administration'.

Goto 'Security' → 'Configure service accounts'.

Step2:

Select the 'web application' from 1^st dropdown list, where you want to change the display name.

Change 'managed account' from 2^nd dropdown list.

It will ask to do IISReset, click on OK.

Now goto the 'web application', see the reflected changes.
