Microsoft today released the March Windows 10 Technical Preview update to testers who have stuck with the "slow" cadence.
The company also posted links to disk image downloads of the newest preview. The images, which are in .iso file format, can be used to create physical installation media for a "clean" install -- one that overwrites the existing OS -- rather than the "in-place" upgrade offered via Windows Update.
Today's update followed the release of the same code a week ago to testers on the "fast" track, or "ring" as Microsoft calls it.
Build 10041 is now available for downloading through Windows Update on devices that have been assigned to the slow ring. The disk images can be downloaded from this page, but require a third-party application to convert the .iso file into installation media such as a DVD or USB flash drive.
The March update's disk image for U.S. customers weighs in at 2.5GB (32-bit) or 3.4GB (64-bit).
Two weeks ago, Microsoft pledged to accelerate the pace of Windows 10 updates, but the firm has not committed to a specific timetable for either the fast or slow rings: Evidence that it will fulfill the promise will come only when Microsoft releases the next fast ring update and, more importantly, sustains a rapid release schedule.
Microsoft has not yet set a definitive release date for Windows 10, saying so far only that it will launch this summer.
