Microsoft released Windows 10 19H1 Build 18237 to Skip Ahead Insiders yesterday, but many users were quick to report high memory usage and installation issues with this release. The Insider team was speedy in investigating the problems, and they've since provided an update, saying the build was re-released after unintentionally being pushed out as encrypted.

If you're still having high memory usage or other issues with the build, the Windows Insider team said that they are still investigating to see if the re-published build resolves the problem. There are no further details beyond that, but Microsoft MVP Rafael Rivera dived deeper into what was causing the problem, explaining the technicalities in a series of tweets.
Additionally, as noted by Richard Hay on Twitter, a symptom of getting this encrypted build could be the much-longer than normal install time. If that's happening to you, it's probably best to cancel the install or pause the update and restart. Did you also have issues installing this build? Let us know in the comments below.
