It has been six weeks and six new Windows 10 desktop builds for Insiders.
The fast release pace that testers have been asking for certainly seems to be on track - at least on the PC Side. I believe this pace is now sustainable because of the background work the Windows team did on their tools for processing and compiling new builds.
We are also seeing more visual updates and changes with each new build which means the work to bring new features to the OS is now underway.
This gallery highlights some of those visual changes in Windows 10 Build 14271 which was released to testers yesterday.
