Microsoft's Internet Explorer, the internet browser that has been part of Windows since 1995, will not be a central part of the next version - Windows 10 - when it launches this summer.
At a conference in the United States where the technology giant confirmed Windows 10 would be launched in 190 countries later this year, the firm's marketing chief Chris Capossela said: "We're now researching what the new brand, or the new name, for our browser should be in Windows 10.
"We'll continue to have Internet Explorer, but we'll also have a new browser called Project Spartan, which is codenamed Project Spartan. We have to name the thing."
When Microsoft held a preview event for Windows 10 in January, it showed off Spartan for the first time, with the software firmly placed as the new flagship browser for the Seattle-based company's operating system.
Spartan was given a demonstration on-stage, with new features that include the ability to edit, annotate and make notes on web pages before saving and sharing them with others.
Microsoft also confirmed that Windows 10, and Spartan, will run across its range of devices, from smartphones to tablets and desktops.
Despite the major re-brand, Internet Explorer will continue in some form - mainly for the benefit of enterprise compatibility, similar to when the firm agreed to extend support for the Windows XP operating system for government and businesses in the UK and Netherlands last year, giving them more time to migrate away from the software that was released in 2001.
Many argue that a re-brand of Explorer was needed, as it has become the butt of web-based jokes for some years now, with users suggesting it was too slow when compared to the competition.
The arrival of competitors such as Mozilla Firefox, Google Chrome and Apple's native browser Safari has seen Explorer and its user numbers steadily decline.
Whether the name Project Spartan will be adopted permanently is yet to be confirmed, but Microsoft is taking steps to push the software out as far as possible.
A new upgrade deal for users in China has just been announced, and Windows will be offered for the first time to those in that country who have an unofficial copy, as Microsoft looks to cut down on piracy issues.
