Microsoft released the Windows 10 October 2020 Update to the public this week, but it's not done squashing bugs. The company pushed out another October 2020 Update test build for Windows Insiders in the Release Preview and Beta channels today, and it's full of bug fixes and improvements. The release notes also mentions the addition of the "Meet Now in Skype" button to the taskbar.

Here's a look at all of what's new in the latest build, which comes in at version 19042.608, according to the release notes:

• Earlier this year we introduced Meet Now in Skype. Meet Now makes it easy to connect with anyone in as little as two clicks for free and each call can last up to 24 hours. Today, we're excited to share that we will be extending this capability in Windows 10 by bringing Meet Now right to the taskbar. In the coming weeks, you will be able to easily set up a video call and reach friends and family in an instant by clicking the Meet Now icon in the taskbar notification area. No sign ups or downloads needed.

• We fixed an issue that displays nothing on the screen for five minutes or more during the Remote Desktop Protocol (RDP) session.
• We fixed an issue that prevents certain Windows Virtual Desktop (WVD) users from searching for files using File Explorer.

• We fixed an issue that occurs when you first sign in to an account or unlock an existing user session using Remote Desktop Services (RDS). If you enter an incorrect password, the current keyboard layout changes unexpectedly to the system default keyboard layout. This keyboard layout change might cause additional attempts to sign in to fail or lead to account lockouts in domains with low account lockout thresholds.
• We fixed an issue that displays the incorrect CPU frequency for certain processors.

When you connect to this type of VPN, an authentication dialog box incorrectly prompts for your credentials.

• We fixed an issue with SQL Server that might cause performance issues if you configure a Linked Server provider to load out-of-process.
• We fixed an issue that might degrade Windows performance and prevent the LanmanServer service from starting when third-party software uses LanmanServer custom file system controls (FSCTL).
• We fixed an issue with deduplication that causes long wait times on Resilient File System (ReFS) Cluster Shared Volumes (CSV).
• We fixed an issue that might prevent some applications from behaving correctly. This occurs when you publish them as Remote Application Integrated Locally (RAIL) applications using Remote Desktop Services (RDS) and change the docking for an AppBar
• We fixed an issue with a deadlock in the Transmission Control Protocol/Internet Protocol (TCPIP) driver that causes the operating system to stop working or stop responding.
