Microsoft Releases Windows 10 Preview Build 19559

Microsoft this week released Windows 10 preview build 19559 to Insiders in the Fast ring. This build follows up last week’s build 19555 which contained mostly bug fixes. Similar to preview builds of late, this one also has no front-facing features. Here’s a look at what you can expect.

Here is the list of general changes, fixes and system improvements contained in this recent Insider build:

  • We fixed an issue with the IME candidate window for East Asian IMEs (Simplified Chinese, Traditional Chinese, and the Japanese IME) not opening sometimes on recent builds.
  • We fixed an issue that could result in explorer.exe crashing when backing out of folders containing .heic or RAW files.
  • We fixed an issue that could result in explorer.exe hanging when attempting to delete certain large .tif files.
  • We fixed an issue resulting in the top few pixels of a window getting clipped when using WIN+Up and then snapping the window to the side using WIN+Left/Right).
  • We fixed an issue resulting in Event Viewer crashing when selecting certain events recently.
  • For any of our Insiders using an arm64 device, such as the Surface Pro X, running Enterprise or Pro edition, you’ll now be able to see and install Hyper-V features.
  • We fixed an issue resulting in some Insiders experiencing a green screen in recent builds with error KMODE EXCEPTION NOT HANDLED.

Important: Windows 10 Insider builds are meant for IT admins, coders, and Windows power user enthusiasts who want to test out new features. If you’re not an experienced user don’t install these builds on your primary production PC. Preview builds contain many bugs and stability issues.

If you are an Insider, keep in mind the Fast ring works differently since the testing of 20H1. The next version is in active development branched called RS_PreRelease. Features that show up in Insider builds moving forward may or may not show up in future stable releases.
