Microsoft has released Windows 10 Insider Preview build 14295 for both the PC and mobile to Slow Ring users. ISO images for the build are also now available, and the new developer tools that were announced at Build 2016 will be made available shortly. This build was released to Fast Ring members just under a week ago, and it brought with it a number of bug fixes for both mobile and PC users, as well as a few issues of its own. If you are a Slow Ring member, you should now see this build available to download.
Should you need the ISO file, you can now grab that now, and shortly the new developer tools will be made available.
