The rapid pace of Windows 10 Preview builds being delivered to my test PC continues. I guess that’s what Microsoft meant when it described this release channel as ‘Fast’.

In the last week or so, my test PC has been updated four times, to Windows 10 preview builds 14383, 14385, 14388, and 14390.

Given that each of these new builds is effectively a new install of Windows 10, they are surprisingly non-intrusive. The downloads are of course large, so there’s a bandwidth consideration. But the downloads happen in the background, and the installs and subsequent restarts happen during off hours (at night). Often I don’t notice the change until I start copying files and notice that Explorer’s copy dialog has once again reverted to its default, simple view.

Note: the Windows 10 version number is no longer visible on the desktop. Microsoft says “the desktop watermark is now gone. This is because we’re beginning to check in final code in preparation for releasing the Windows 10 Anniversary Update”. I’m not sure I follow the logic there, but at least it’s somewhat consistent. The watermark stops appearing when a release is imminent.
