Today, Microsoft is releasing its latest preview updates for supported versions of Windows 10. These updates are also known as ‘C’ and ‘D’ week updates, with the letter standing for the week of the month (Patch Tuesday, which is the second week of the month, is the ‘B’ week update). Being that all supported version of Windows 10 get the same bits, they’re all getting the same update today.

Specifically, the update is for Windows 10 versions 21H1, 20H2, and 2004, and KB5004296 will bring the build number to 19043.1151, 19042.1151, and 19041.1151, respectively. You can manually download it here, and these are the highlights:

  • Updates an issue that prevents gaming services from opening certain games for desktop users.
  • Updates an issue that prevents you from entering text using the Input Method Editor (IME). This might occur, for example, after startup if you have set the power options to shut down a laptop by closing its lid.

  • Updates an issue that plays the sound for selecting something in a game loudly when you press the trigger button on a game controller.
  • Updates an issue that prevents power plans and Game Mode from working as expected. This results in lower frame rates and reduced performance while gaming.
  • Updates an issue that fails to detect that you are connected to the internet after you connect to a virtual private network (VPN).
  • Updates an issue that causes printing to stop or prints the wrong output. This issue occurs when you print using a USB connection after updating to Windows 10, version 2004 or later.

As usual, there are a ton of fixes as well. Here’s the full list:

There are actually a few known issues as well:

Symptoms Workaround
When using the Microsoft Japanese Input Method Editor (IME) to enter Kanji characters in an app that automatically allows the input of Furigana characters, you might not get the correct Furigana characters. You might need to enter the Furigana characters manually.

Note The affected apps are using the ImmGetCompositionString() function.

We are working on a resolution and will provide an update in an upcoming release.
Devices with Windows installations created from custom offline media or custom ISO image might have Microsoft Edge Legacy removed by this update, but not automatically replaced by the new Microsoft Edge. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone servicing stack update (SSU) released March 29, 2021 or later.

Note Devices that connect directly to Windows Update to receive updates are not affected. This includes devices using Windows Update for Business. Any device connecting to Windows Update should always receive the latest versions of the SSU and latest cumulative update (LCU) without any extra steps.

To avoid this issue, be sure to first slipstream the SSU released March 29, 2021 or later into the custom offline media or ISO image before slipstreaming the LCU. To do this with the combined SSU and LCU packages now used for Windows 10, version 20H2 and Windows 10, version 2004, you will need to extract the SSU from the combined package. Use the following steps to extract the using SSU:

  1. Extract the cab from the msu via this command line (using the package for KB5000842 as an example): expand Windows10.0-KB5000842-x64.msu / <destination path>
  2. Extract the SSU from the previously extracted cab via this command line: expand /f:* <destination path>
  3. You will then have the SSU cab, in this example named Slipstream this file into your offline image first, then the LCU.

If you have already encountered this issue by installing the OS using affected custom media, you can mitigate it by directly installing the new Microsoft Edge. If you need to broadly deploy the new Microsoft Edge for business, see Download and deploy Microsoft Edge for business

After installing the June 21, 2021 (KB5003690) update, some devices cannot install new updates, such as the July 6, 2021 (KB5004945) or later updates. You will receive the error message, “PSFX_E_MATCHING_BINARY_MISSING”. For more information and a workaround, see KB5005322.

As mentioned above, this is an optional update. You can obviously download it and install it manually from the Update Catalog. You can also get it through Windows Update. If you go to Settings -> Update & security -> Windows Update and check for updates, you’ll be presented with an option to download and install this. You can ignore it if you want to. If you do, these fixes will be bundled into next month’s Patch Tuesday update for Windows 10, and that will be mandatory.

If you’re on Windows 11, you’re not receiving regular Patch Tuesday or optional updates. Preview builds are updated on a different schedule.
