the latest and most exciting Windows 10 build 16299.15(fast ring) on lumia 1020
Windows 10 build 16299.15 is rolling out to Insiders in the Fast ring.
Microsoft is rolled out the final build of the Fall Creators Update to Insiders in the Fast ring on oct 2nd 2017, which is packing new bug fixes and changes. This is the final build, also known as the Release To Manufacturing (RTM) build, which means from here on out Microsoft will be servicing build 16299 with cumulative updates and patches.
The Fall Creators Update is pretty much done at this point. From here on out, Microsoft will be fixing any last minute bugs via patches installed through Windows Update, rather than using full new builds. 16299.15 is the last full build Insiders will receive for the Fall Creators Update.
With build 16299.15, you can clean install or leave the Insider Program without worry of your install eventually expiring under the Insider Preview. This is the official, non-preview release of the Fall Creators Update.
