Here's what's fixed, improved, and still broken in Windows 10 build 18950

With another week comes another build of Windows 10 for Insiders in the Fast Ring, and though this one isn't exactly full of new features, it does include some improvements to the Japanese Input Method Editor. It also comes with a relatively small list of known issues and bug fixes.

Earlier this week, references to a cloud restore option were spotted in a leaked variant of this build, but Microsoft is warning that the feature isn't quite available to try out yet. Here's what's changed in build 18950:

  • Insiders may notice some references to “Cloud download” relating to PC reset or refresh. This feature isn’t available and working quite yet. We’ll let you know once it is, so you can try it out!
  • We fixed an issue where ctfmon.exe might crash if clicking the input mode indicator in the taskbar to switch the Japanese IME between modes.
  • We fixed an issue where pasting from clipboard history (WIN+V) wouldn’t work when using the Bopomofo IME.
  • We fixed an issue resulting in hanja conversion not working for the updated Korean IME when typing in certain apps.
  • We fixed an issue that could result in the OneNote app intermittently acting as if the Ctrl key was pressed when it wasn’t.

Of course, this build still comes with its own set of known issues, and the list is almost unchanged from last week's build. Here's what to look out for:

  • There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. We are also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds and will work to minimize the likelihood of these issues in the future.
  • Some Realtek SD card readers are not functioning properly. We are investigating the issue.
  • Tamper Protection may be turned off in Windows Security after updating to this build. You can turn it back on. In August, Tamper Protection will return to being on by default for all Insiders.
  • Occasionally, the candidate selection in prediction candidate window for the Japanese IME doesn’t match with the composition string. We are investigating the issue.

As we always note when these builds get released, the 20H1 development cycle is still in its early stages, and though there may not be any major known problems in this build, that doesn't mean there won't be any in the future. They may also show up even if Microsoft isn't aware of them. At this point, 20H1 builds don't have a lot of new features, so it may be best to wait a little longer before jumping into the Fast ring.
