Windows 10 Spring Update Delay Explained as Microsoft Releases New Build

After a bug was discovered before public deployment of Redstone 4, the company delayed the release, fixed the issues, and rolled out a new Insider build.

Microsoft today released Preview Build 17134 to Insiders in the Fast ring and explained the delay of the public release of Redstone 4. It was originally thought that the last Insider release, Build 17133, was the final version or “RTM” to be released during last week’s Patch Tuesday. However, it should be noted that Microsoft never made an official announcement on the release date of the Windows 10 Spring update otherwise known as Version 1803.

Windows 10 Build 17134

The dev team found a major bug in Build 17133 that had reliability issues and caused many systems to BSOD and decided to hold off on the release. The earlier detected bugs should be fixed with this new build, and it’s likely this will be the actual final version of Redstone 4 that rolls out to everyone.

In a new blog post for Insiders, Dona Sarkar notes: “Today, we are releasing Windows 10 Insider Preview Build 17134 (RS4) to Windows Insiders in the Fast ring. This build has no new features and includes the fixes from KB4100375 as well as some fixes for general reliability of the OS. As Build 17133 progressed through the rings, we discovered some reliability issues we wanted to fix. In certain cases, these reliability issues could have led to a higher percentage of (BSOD) on PCs for example. Instead of creating a Cumulative Update package to service these issues, we decided to create a new build with the fixes included.”

There is speculation that the final public release of Version 1803 might be a few weeks away yet. Microsoft needs to go through some testing of this latest build with Insiders. And will need to test a cumulative update with it, too. Still, it’s for the best that the bug was caught early before the public release, as the company doesn’t need to have massive issues when the official feature update rolls out to everyone.




    I was scared with that 17133 was getting the blue screen death more often than not on my system …!! so far build 17134.1 is stable !! woohoo go Microsoft!!! Look stable enough that I installed it on my main PC as i use my laptop for the insider program
    have a question now that build 17134.1 is the fix and new RTM can I leave the insider program on my main machine? or set it to just fixes apps and drivers so can continue to receive updates until its release to the public? the Laptop is my main testing preview pc
