Windows 10 build 17133 isn’t RTM for version 1803 anymore

Following the delay of Windows 10 version 1803, Microsoft now is no longer considering build 17133 as final as the company is expecting to release new builds to fix blocking bug.

Although Windows 10 version 1803 — dubbed “Spring Creators Update”– was originally planned to launch during the second week of April, Microsoft had to delay the official release as a result of a bug that could impact systems, and instead, it ended up rolling out a quality update that bumped the build number to 17133.73.

According to a new report from Windows Central, sources are now revealing that Microsoft internally no longer is considering Windows 10 build 17133 as the final build (or release to manufacturer “RTM”) for public release. This news now suggests that the bug isn’t fixable with a patch, as we’re expecting to see more new builds beyond 17133 releasing to testers.

If you’re an Insider running build 17133, chances are that you’re not going to experience significant problems, but the bug is there.

Outside of Microsoft no one exactly knows the problem with version 1803, but seeing that new builds will continue to come, it appears that it’ll take a little longer to complete the Redstone 4 development.

If you have a device enrolled in the Fast, Slow, or Release Preview, no extra steps need to be taken as when a new build with the fix releases, it’ll download and install automatically. However, in the case that you use the upgrade process to jump to version 1803 from version 1709 (Fall Creators Update) early, you may want to consider rolling back and wait until the blocking bug is fix.

Microsoft isn’t sharing any information publicly, which makes it a lot harder to get an idea when the release date for Windows 10 version 1803 will be. However, Brandon LeBlanc, Senior Program Manager at Microsoft has tweeted that Insiders are not likely to see new builds in the Fast ring for some time.
