Windows 11 Insider Preview channels — Beta and Dev Channels — are going their separate ways with different build numbers, features, and changes. The latest Windows 11 Insider Preview ISOs come in two different build numbers this time with Beta channel getting v22000.176 and the Dev channel getting a major update with build 22449.1000. Microsoft also made the latest Windows 11 ISO downloads available directly from their server. Check out the new update and all of its details below.

As for the update log, Windows 11 Beta Channel with build 10.0.22000.176 features changes to the taskbar shortcuts. The most commonly used experiences like Search, Task View, Widgets, and Chat are now pinned to the Taskbar in Windows 11.

What’s new with Windows 11 Insider Preview Build 22449.1000 Dev Channel?

Major changes come to the Windows 11 Dev Channel with build 22449.1000. As this is a more experimental channel, it is expected that Microsoft will add critical changes to it.

For one, SMB compression behavior has now changed starting build 22449. Microsoft will no longer use the formerly implemented decision algorithm by default. Instead, if compression is requested, Windows will always attempt to compress. You can also modify this new behavior and return to a decision algorithm, using this tutorial: Understanding and controlling compression behaviors.

Context to the SMB compression:

We first introduced SMB compression in Windows Server 2022 & Windows 11. SMB compression allows an administrator, user, or application to request compression of files as they transfer over the network. This removes the need to first deflate a file manually with an application, copy it, then inflate on the destination PC. Compressed files will consume less network bandwidth and take less time to transfer, at the cost of slightly increased CPU usage during transfers.

Based on testing and analysis, we have changed the default behavior of compression. Previously, the SMB compression decision algorithm would attempt to compress the first 524,288,000 bytes (500MiB) of a file during transfer and track that at least 104,857,600 bytes (100MiB) compressed within that 500-MB range. If fewer than 100 MiB were compressible, SMB compression stopped trying to compress the rest of the file. If at least 100 MiB compressed, SMB compression attempted to compress the rest of the file. This meant that very large files with compressible data – for instance, a multi-gigabyte virtual machine disk – were likely to compress but a relatively small file – even a very compressible one – would not compress.

Of course, this behavior is not yet permanent. You can send feedback or report issues with SMB compression, under the Files, Folders, and Online Storage > File Sharing category.

Other changes include:

  • The boot screen now shows a progressive ring animation for loading the OS instead of an animated circle of dots. We are working to replace this animated circle of dots in other areas of the OS over time.

  • Right-clicking on the Bluetooth entry in Quick Settings and selecting Settings will now open the main Bluetooth & Devices page in Settings.
  • The Windows startup sound will no longer play after an unattended update (aka a scheduled Windows update when you are not at your PC).
  • Added a link to the touch keyboard personalization settings from Typing > Touch Keyboard to help improve discoverability.
  • Notifications now have an acrylic background.
  • Updated animation used in the notification introducing you to Windows Hello if it hasn’t been set up.
  • Updated the dialog when closing Windows Sandbox so that it has rounded visuals.
  • Adjusted the design of Notification Center to make the app names more visibly separated from the notifications.
