Microsoft has announced it will offer a preview version of its first major update to Windows 8 next month.

The news comes amid growing criticism of the software's user interface.

Microsoft said the revision to the operating system (OS), codenamed Windows Blue, would be released at Build, a three-day developers event in San Francisco starting on 26 June.

However, while the company said it had listened to "feedback", it has still not disclosed what changes are planned.

Microsoft added that a final version of Windows Blue would be released before the end of the year, and highlighted that it had already sold more than 100 million licences for the system.
