Microsoft confirmed on Tuesday that it is looking into an issue in which users of Internet Explorer 6 are forced into having Bing as their default search engine.
"We are aware of the issue with Bing on machines running IE6 and are investigating a solution," Microsoft said in a statement. "This issue is not impacting IE7 and IE8 users."
Although it is only affecting its older browser, many people still use IE6 and Microsoft has faced a lot of regulatory scrutiny over how default search preferences are set and changed within Internet Explorer.
The IE6 issue was noted earlier on Tuesday by Search Engine Land.
