Known issues

A few bugs still occur even after applying Build 19559 to your Windows 10 Device. They are as follows –

  • Compatibility Issues on certain games while using anti-cheat programs altogether. BattlEye is one such application where insiders feel difficulty playing games.
  • Narrator and NVDA users still face trouble while using latest Chromium Edge version by Microsoft. The problem arises primarily when you attempt to either navigate or read web content. 
  • Windows 10 Update section still hangs while applying a newer build on the PC. 
  • A few error may pop in such as – 0x8007042b, 0xc1900101, etc. when Insiders attempt to update their OS.
  • Certain IMEs will not appear if you ever upgrade or degrade your existing Windows 10 Build to Higher/Lower versions. If that’s the case, just remove the particular language pack thereafter re-install it back. To do so, browse to the following path – ” Settings > Time & Language > Language > Preferred languages”.
  • Recently, a few Windows users have reported about missing Sleep button under Power options. The company is currently looking in to this matter and may provide a resolution to this in an upcoming release. 
  • Under Privacy, there appears a broken icon and it represents the Document section. 
  • WSL Issue 4860 will remain even after installing Build 19559 on your computer. 

That’s it, we hope you get a clearer picture of what happens after applying this Build to your system.
