KB5037008: Microsoft finally corrects RAM speed in Windows 11 with build 22635.3570

A Windows 11 Insider Preview banner

Microsoft today has released a new Beta Channel build for Windows Insiders. The new build, 22635.3570 under KB5037008, brings improvements to File Explorer as it adds the ability to duplicate tabs. It also fixes several bugs in the app.

The new build also brings Task Manager improvements. It will finally correctly read DDR RAM speed as MT/s instead of MHz. DDR or Double Data Rate essentially means that the data throughput is doubled per frequency. So for a DDR5-6000 memory stick, the RAM frequency is actually 3000 MHz instead of 6000 MHz as was incorrectly reported by the Task Manager previously. So now this will correctly display 6000 MT/s.

The full changelog is given below:

[File Explorer]

  • Fixed a memory leak when interacting with archive folders in File Explorer.
  • Fixed a few issues impacting File Explorer reliability.
  • Made a change to help fix an issue which could cause the spacing between your desktop icons to become extremely wide.
  • Fixed a timing issue where if you start a search from Home in File Explorer, it may unexpectedly show no results the first time you tried.
  • Did some work to help address an issue where the address bar dropdown might appear unexpectedly while you were using File Explorer.

[Task Manager]

  • Updated the units (from MHz to MT/s) for DDR speed.
  • Fixed an issue where the Safely Remove Hardware option for ejecting USB devices wouldn’t work if Task Manager was open.
  • Did some work to ensure Task Manager releases process handles quickly when terminating processes.
  • Made some more improvements to help with Task Manager reliability.
  • We have improved the performance when changing the sort order.
  • Made multiple improvements to overall accessibility of Task Manager, including improving keyboard focus, tab navigation, text scaling, names of items read out by screen readers, and more.
  • We made it a little easier to resize Task Manager when trying to resize by grabbing the top of the window.

Changes and Improvements gradually being rolled out to everyone in the Beta Channel

[Copilot in Windows**]

  • Over the last few months, we’ve been trying out different experiences for Copilot in Windows (Preview) with Windows Insiders across the Canary, Dev, and Beta Channels. Some of these experiences include the ability for Copilot in Windows to act like a normal application window and the taskbar icon animating to indicate that Copilot can help when you copy text or images. We have decided to pause the rollouts of these experiences to further refine them based on user feedback. Copilot in Windows will continue to work as expected while we continue to evolve new ideas with Windows Insiders.

Fixes for everyone in the Beta Channel

[Start menu]

  • We fixed the issue causing a component related to upgrading and restoring data from Windows Backup called “Global.WindowsMigration” to incorrectly show under the Start menu > All apps.

[Copilot in Windows**]

  • We are rolling out a fix for the issue causing Copilot to auto-launch unexpectedly for Windows Insiders in the Canary, Dev, and Beta Channels after restarting their PCs. This issue was unrelated to the auto-launching experience we tried out with Insiders in the Canary and Dev Channels in early February which we stopped rolling out in March.

Known issues


  • We are investigating an issue where Internet Information Services (IIS) and Windows Communication Foundation (WCF) may not work after installing this update.


Windows Insiders in the Beta Channel who have the new position for the Widgets entry-point on left-aligned taskbars may see the following known issues:

  • Swipe invocation for Widgets may not work if taskbar is center-aligned instead of left-aligned.
  • Unpinning Widgets from the taskbar may not work if taskbar is center-aligned instead of left-aligned.
  • The Widgets board is incorrectly positioned when Copilot is in side-by-side mode.
  • Turning on/off Widgets in taskbar settings may refresh the taskbar.
