Microsoft is expected to drop the Windows 8 brand following user criticism since its high profile launch in 2012.
The operating system was tipped to secure the technology giant's place on the tablet market, but sales have been poor and customers have not responded well to its colourful tile interface and lack of many Windows staples, such as the 'Start' button.
An update, Windows 8.1, was released last year but the company is ultimately expected to scrap the brand for a new operating system, codenamed Threshold. It is expected that the replacement will simply be called Windows 9 when it is rolled out in 2015.
Respected Microsoft blogger Paul Thurrock wrote on his website: "To distance itself from the Windows 8 debacle, Microsoft is currently planning to drop the Windows 8 name and brand this next release as Windows 9. That could change, but that's the current thinking."
Microsoft is hoping make up lost ground to rivals Apple and Google in the tablet market in time for the Christmas.
ITV News' Lewis Vaughan-Jones reports.
Pricing has been announced for Microsoft's Surface tablet, at $499 for a 32GB computer.
This puts it as one hundred dollars more expensive than the iPad, but with double the memory.
Microsoft has started shipping its first Surface tablet computers ahead of the official launch tomorrow.
Microsoft's UK site says it has sold out of pre-orders for the 32GB version of the device.
Windows 8 will power a "new generation of all in one PCs", according to Microsoft's Steven Sinofsky.
Many of the new PCs running Windows 8 will have a touchscreen feature, with users being able to swipe and use gestures as well using as a keyboard and a mouse.
Steven Sinofsky, Microsoft's head of Windows has announced that Windows 7 has been installed 670 million times.
He says that Windows 8 is "computing for the next billion people", and sees it as a shift from the old age of desktops to the age of touchscreens, smartphones, and social networking.
"Windows 8 is simply the best release of Windows ever," he said.
Technology website Gizmodo has summed up Windows 8 as "incredibly innovative, incredibly important, not quite incredible."
In a review of the new operating system, Kyle Wagner said: "If you want, you'll be able to operate more or less as you have in Windows 7, with some minor changes, mostly for the better.
"That's what desktop mode is for. But the writing is on the wall. Nearly all of the features in need of upgrades that have been left largely untouched are associated with the non-Metro desktop and its structure."
