Windows 10 was made available for PC users at the end of July, but Microsoft is already moving ahead with new features, delivering the first post-launch technical preview to testers with memory management and user interface enhancements.
Microsoft has said that Windows 10 will be different from earlier Windows releases, in that it will be regularly updated with new features delivered via Windows Update over the lifetime of the platform.
The company has now made good on that promise with a new Build 10525 of Windows 10 released to testers on the Fast ring of the Windows Insider preview programme.
This provides new features and capabilities that Microsoft will roll out to Windows 10 once it has had time to analyse feedback from the Windows Insider community and fix any problems.
The chief new feature is support for compressed pages, enabling Windows to compress unused areas of memory instead of paging them out to disk, which takes time and causes a delay if the memory is suddenly needed again.
This is implemented using a new concept in the Windows Memory Manager called a compression store, an in-memory collection of compressed pages, according to Gabe Aul, Microsoft's director of programme management for the Windows Fundamentals team.
"When Memory Manager feels memory pressure it will compress unused pages instead of writing them to disk. This reduces the amount of memory used per process, allowing Windows 10 to maintain more applications in physical memory at a time," he wrote on the Windows blog.
This will also help provide better responsiveness across Windows 10, he added.
A less significant feature is an update on colour options in the user interface, specifically the default colour for Start, Action Centre, Taskbar and Title bars. Microsoft said that it received lots of feedback from users who said they wanted these features to change to reflect individual preferences, and this is given an early implementation in Build 10525.
However, there are some problems with the build, such as mobile hotspot functionality not working and optional language packs not currently being available.
Those on the Windows Insider programme will automatically be upgraded, or can upgrade their system via Windows Update, Microsoft said.
