Last week, Microsoft was supposed to release Windows 10 “Spring Update” or Redstone 4 as it is codenamed. However, we reported that the company was forced to delay the official launch after finding a bug in the RTM (build 17134) preview. Now it seems the bug is widespread, but could it stop the update from going official this month?

While the flaw is being reported a lot by Insiders, it is not happening to everyone and has not affected Redstone 5 builds currently in preview. Microsoft described the problem as a blocking bug that causes BSODs.

Some users also report build 17134 also has a problem with the Settings app, where initiating the application causes a crash. I wrote a week ago that Microsoft catching this problem before an official roll out was a good thing. However, we are now left wondering exactly when the next upgrade for Windows 10 will arrive.

Judging by the new rumored name for Redstone 4, Microsoft is still working to launch it this month. We have been calling Redstone 4 the Spring Creators Update or Spring Update for several months.

Windows 10 April 2018 Update

Despite this, it seems Microsoft has decided to simply name the upgrade Windows 10 April 2018 Update. It’s actually a naming method (month, year) that is simply and more effective than looking for interesting monikers for updates.

Of course, that very name suggests Microsoft should be aiming to still release Redstone 4 to the masses before the end of the month. Of course, the blocking bug may yet scupper the company’s plans, so we could be looking at a May release of Windows 10 April 2018 Update.

Microsoft is working on fixing the flaws (blocking bug and Settings mishap) in preview builds now. The company will also issue a cumulative patch on day one of official release to shore up RTM builds against the problems.
