In the past few days early adopters have been able to give people a sense of what's to come, thanks to a leak of a next-generation version of Windows that appeared online last week.
The leaked build contains a variety of changes, many of which Microsoft could describe at its virtual event on Thursday.
If the next version of Windows looks anything like the leaked build, then it will be borrowing elements from the shelved Windows 10X, which had originally been conceived to run on dual-screen PCs, for an operating system that went by the name Windows 11.
The build incorporates a new Windows icon with four equally sized squares, unlike the icon used for Windows 8 and Windows 10 with window panes that widen from left to right.
The leaked build came with a few new ways for users to customize their PCs.
Some of the people who installed the leaked Windows 11 build ran tests and found that the operating system delivered faster performance than the latest version of Windows 10, which itself was advertised as being "fast and familiar" when it was released in 2015.
One place developers can expose their applications to end users in Windows is Microsoft's app store.
