Microsoft hasn’t released any new builds for Windows 10 PCs and Mobile this week. It’s been two weeks since Windows Insiders received an update for PCs on the Fast Ring. Microsoft has finally revealed the reason behind the absence of new preview builds for Windows 10.

The program manager in the Windows Insider team, Jason Howard has briefly explained in a blog post the reason behind the lack of preview builds for more than two weeks. The company was internally testing build 16262 and the update had a bug in Photos app that prevents the users from printing the photos.

“We know a lot of folks use this app, but a bug of this type wouldn’t normally stop us from sending a build to the Fast ring. We logged it and put it on the known issues list for the flight and were planning to move forward. As we gathered more data from testing in the Selfhost ring internally, we found that this bug was much larger in scope. It turns out this bug affected an entire class of functionality and would potentially impact nearly 40% of users in various ways (printing, adjusting settings, pairing Bluetooth devices, etc.). Once the scale of the bug was fully understood, the decision to waive off the flight was made”, Microsoft explains.

Microsoft later started testing build 16267 for this week’s release but they failed to release the update as it had the rollback issue. “PCs would boot into the offline phase to begin the install and during the process, users would hit a blue screen failure. The affected PCs would roll back to their current build successfully, but this experience was semi-broad in scale,” says Jason Howard. He further notes as the workaround success rate wasn’t high enough, Microsoft had to give up on the build and start looking for a new release candidate.

While on other hand, there have been no new builds for Windows 10 Mobile as the company prefers to release preview builds for both PC and Mobile together as it helps to make things easier on the feedback and fighting systems.
