Microsoft's Windows 10 technical preview is available for both the desktop and phones. However, the timing and frequency of the updates are not too great. We've already heard from Microsoft that there's one bug which is blocking the update for the next build, but there's no word about the next build for phones, which is expected to bring support for more devices.
Recently, Microsoft mentioned the company plans to speed up the build releases for users in the Fast ring, and now have posted a message to the Insider Hub detailing their plans to make the Fast Hub faster:
We’ve heard your feedback asking for more frequent builds—and as Gabe mentioned in his recent blog post, we’ve probably been too conservative about pushing builds to the Fast ring for Windows Insiders. So we’re preparing to speed up the build releases for those who want to live life in the Fast lane.
The good news is that Insiders who choose Fast will be getting fresher code, with all of the features and fixes, more often. The potential downside is that as we go faster, the builds will likely include more bugs with fewer workarounds. If this doesn’t sound like something you want to deal with, now is your time to switch to Slow.
If you hate bugs, and want to try a stable build, then it's recommended that you opt for the "Insider Slow" option. If you're running the desktop version of the technical preview, head over to Settings > Update & recovery > Advanced options and change it to "Slow". As for phones, Just open the Windows Insiders app, and change the enroll setting to Insider Slow. Or, if you're like us, set it to FAST!!!!!
