Windows 11 adds duplicate tabs to File Explorer and corrects RAM speed on Task Manager (build 22635.3570)

Microsoft releases two minor updates for Windows 11 in the Beta and Dev Channels, and nothing for the Canary Channel.

  • Microsoft introduces a duplicate tabs option for File Explorer on Windows 11.
  • Task Manager updates memory speed to show the correct MT/s unit instead of MHz.
  • The company also stopped and removed two experimental features coming to Copilot.

On May 3, 2024, Microsoft rolled out two new previews of Windows 11, including build 22635.3570 (KB5037008) in the Beta Channel and build 26120.461 (KB5037009) in the Dev Channel from the Windows Insider Program. These are minor updates that only push new channels. Also, the company notes that the Canary Channel won’t include a new build until there’s a good preview to share with Insiders.

Windows 11 build 22635.3570 changes

According to the official notes, Windows 11 build 22635.3570 introduces the ability to duplicate tabs on File Explorer. This feature was spotted in the previous build, but it was hidden. Now, the feature is available to everyone. In addition, this flight rolls out a few fixes for the default file manager.

The update also brings a noticeable change to the Task Manager. It now measures DDR speed in MT/s instead of MHz. This change, while seemingly small, can have a significant impact on how users monitor their system’s performance.

For a little context, MHz (Megahertz) and MT/s (Megatransfers Per Second) are two ways to measure the speed of DDR memory, but they represent slightly different things. On one hand, MHz refers to the memory’s clock speed, essentially how many times it can change voltage per second. On the other hand, MT/s reflects the actual data transfer rate of the memory, indicating how much data it can move per second.

In the past, MHz and MT/s were identical for SDR (Single Data Rate) memory. One data transfer happened per clock cycle. However, things changed with DDR (Double Data Rate) since this type of memory can transfer data on both the rising and falling edges of the clock cycle, effectively doubling the data transfer rate compared to SDRAM at the same MHz.

So this means that the “Performance” tab for Task Manager will now show the correct speed in MT/s instead of MHz. For example, a 3200 MHz DDR4 memory module will now appear as 3200 MT/s because in MHz, technically, the memory is running at 1600 MHz.

Finally, the company is shipping some rendering improvements and reliability changes as part of the Task Manager update.

As part of the Copilot changes, Microsoft has decided to stop two experimental features, including the ability to use the chatbot AI as a regular application and the animation of the icon when copying text or an image to the clipboard. However, the Copilot action menu is still available, and it’ll appear from the bottom-right corner when copying text or images to the clipboard.

Windows 11 build 26120.461 changes

Microsoft is also rolling out the Windows 11 build 26120.461 (KB5037009) in the Dev Channel, but this is not an entirely new build. It’s only an enablement package for users with the option to receive a preview for updates turned on in the “Windows Update” settings page.

As I mentioned above, the update doesn’t introduce anything new other than the same changes for Copilot and some general fixes.

Finally, it has been spotted by @PhantomOfEarth on X in this preview that the system hides the preview icon of AI Explorer.

AI Explorer is the new timeline feature that docks at the top of the screen, and it will make all your activities searchable using natural language.

Installing this preview build

To download and install the Windows 11 build 22635.3570 (KB5037008), enroll your device in the Beta Channel through the “Windows Insider Program” settings from the “Update & Security” section. Once you enroll the computer in the program, you can download the build from the “Windows Update” settings by turning on the “Get the latest updates as soon as they’re available” option and clicking the “Check for Updates” button.

Enroll the device in the Dev Channel if you want to install the build 26120.461.
