Microsoft unveils Windows 11 operating system
Product manager Panos Panay promised smaller, faster security updates - a common complaint for Windows users - and said they would happen in the background.
Windows 11 will be available as a free update to existing Windows 10 users - although some devices will not have the right specifications. These include a minimum of 64 gigabytes of storage and 4 gigabytes of RAM.
In addition, Windows 11 will feature tighter integration with Microsoft's communications platform Teams. Xbox Games Pass, a subscription service offering access to hundreds of games, will also be pre-installed.
The tech giant said it would share more profits from its app store with creators and developers - as rival Apple continues to face challenges over its business model.
When Windows 10 launched in 2015, Microsoft said it would be the final version of the operating system. It has since announced Windows 10 will be retired in 2025.
Microsoft chief executive Satya Nadella described the launch as "a major milestone in the history of Windows", but analyst Geoff Blaber from CCS Insight said he did not consider it to be "a revolutionary step".
