Changes[edit | edit source]

The phone screen feature that was introduced in May 2019 Update build 18356 now supports seven more phone models, these are the OnePlus 6, OnePlus 6T, Samsung Galaxy S10e, S10, S10+, Note 8 and the Note 9.
Dictation now supports twelve more languages, these include Canadian English, British English, Australian English, Indian English, French, Canadian French, German, Italian, Spanish, Mexican Spanish, Brazilian Portuguese, and Simplified Chinese. To try them out, the packages for the desired language have to be downloaded first.
Narrator Find now works more reliably in the Google Chrome web browser.

Bugs[edit | edit source]

Older versions of anti-cheat software for games can cause the PC to crash with a green screen of death.
Some Realtek SD card readers do not function correctly with this build.
If you use Remote Desktop to connect to an enhanced session VM, the taskbar search results will not be visible and thus display a blank area instead until you restart searchui.exe.
On some devices, if fast startup is enabled, the night light feature won't turn on unless the device is rebooted.
There is a noticeable lag when you drag the emoji and dictation panels.
Tamper Protection may be turned off in Windows Security after updating to this build. It can be turned back on after the update is complete.
Some features on the Start menu and the all apps section aren't fully localized in some languages such as French, Simplified Chinese, and Russian.
If you try to restore a previous version of Windows, you will get an error message that says the account "NT Service\wlpasvc", before you can continue. To bypass this, open Registry Editor, then navigate to HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList, then search for wlpasvc, and then delete the node that contains wlpasvc, which is different for each user of the system.
