Windows 10 21H1 Version 19043.783

The Microsoft team in Redmond has released an update (KB4598291), which they plan to release in early June. Currently, only insiders can test it (Windows Insiders), but the update can be downloaded as a "cab" file from the link below and anyone can install it now. If you have updated regularly, the latest version is Windows 20H2 Build 19042.746, and after the update by installing the KB4598291.cab file, it will be Windows 20H2 Build 19042.782.

Quick Tip: The cabinet file KB4598291 (.cab) already includes the update scheduled for June, but is not enabled. If you read the post below, you'll learn how to activate it now.


Latest version of Windows:

Microsoft Windows system installed on my computer: Windows 10 Pro, version 21H1, operating system build number: 19043.783, Quality: Windows Feature Experience Pack 120.2212.2020.0.

First step: Upgrade to the new version 19042.783 using the command line:

Warning: The installation of the described update can only be applied at your own risk!

There are two ways to install the KB4598291 file:

  1. Upgrading to version 19042.783 by installing KB4598291.cab from the command line:
  2. By adding an "Install" button:

First installation option:

Upgrading to version 19042.783 by installing KB4598291.cab from the command line: The first installation option is not complicated and even if you do not know what you are doing, you can try to install it, at most the command line stops without any consequences.

The second example is a little easier, but requires caution, as you need to add an entry to the database, which can cause an uninitiated error and can even cause the system to crash or reinstall.

Quick Tip: I chose the second option because the update was simple and error-free.

Run Command Prompt as an administrator (Start menu / Windows folder / Command Prompt) and type the next command manually or by a simple copy-paste. Select the code with the mouse, then press Ctrl + C to copy. To paste press Ctrl + V then press Enter:

dism /online /add-package /packagepath:"cab_package_path"

In the command line above only the cab_package_path part needs to be rewritten depending on where you saved the downloaded "cab" file.

For example (if the cab file is in the download folder):

dism /online /add-package /packagepath:"C:/Users/John/Downloads/Windows10.0-KB4598291-x64_bec6623215c12f7fbd1c759e3d10f318bf04d0d8.cab"

For example (if the cab file is in the download folder):

dism /online /add-package /packagepath:"C:/Users/John/Desktop/Windows10.0-KB4598291-x64_bec6623215c12f7fbd1c759e3d10f318bf04d0d8.cab"

In the line of code above, the name "John" should be replaced with the name of the computer you entered during installation and also displayed on the login screen.

Finally press Enter. The sample command installs the KB4598291 update for 64-bit systems.

After successful installation, you will be prompted to press Y (YES) on the keyboard if you restart your computer immediately to apply the update, or press N (NO) if you restart later.

(If you fail, use the second installation option below. It's easier!) .

Second installation option:

To install an update, simply add an "Install" button: It's very simple. All you have to do is add an option to the database named "Install" which will be embedded in the mouse menu and if you right click on the downloaded "cab" file, the install button will appeared in the mouse pop-up window. Just click this button and the update will be installed automatically. In this case, there is no need to manually execute the above DISM command via the command line.

Do the following:

Copy the following code into Notepad and save it in .reg format (for example, update.reg). Then left-click on the file to apply its contents to the registry. The code:

Windows Registry Editor Version 5.00 [-HKEY_CLASSES_ROOT\CABFolder\Shell\RunAs] [HKEY_CLASSES_ROOT\CABFolder\Shell\RunAs] @="Install" "HasLUAShield"="" [HKEY_CLASSES_ROOT\CABFolder\Shell\RunAs\Command] @="cmd /k dism /online /add-package /packagepath:\"%1\""

After these manipulations, the "Install" option will be available by right-clicking on the CAB file.

Installation update for KB4598291

The first step is over.

If you open the Windows "About" window after rebooting, you'll see the new version number.

To check the version installed on your computer, press Windows -Logo + R on the keyboard simultaneously, and type the word winver in the Run window that appears, and then press Enter. In the About Windows box displayed, next to the Version entry, you will find the current version number.

Step two: Activate & update Windows-10 to 21h1-19043.782:

Recommended for those who have a backup computer for testing, and if the testing is successful, you can try it on your own machine (I tried it on my machine and installed it without any error). Note that your computer must be running at least Release Channel Build 19042.782 with the KB4598291 update application installed (or one of the Windows Insider Preview Beta systems).

If you have an older version of Windows installed, update it first using Windows Update. The function can be started as follows: Start menu (taskbar, left corner Windows -Logo) / Settings (wheel icon) / Update and Security.

It is necessary to upgrade to at least version 19042.782, because according to the information disclosed, the next major update (spring 2021) 20H1 19043.782 already includes the patch KB4598291, just waiting to be activated.

A command line has already appeared on DeskModder.de that activates the spring update that is currently on your computer. I found this DISM script on this site, which you can read here: Update version 19043 (German and English code) »»


19043, also known as 20H1. Putting DISM Commands together

In essence, the following command lines bring together update packages that are already behind the scenes.

Quick Tip: This DISM script runs a series of .mum files, which are essentially XML files and instruct Windows Update to activate existing files.

The following codes can be started from a command line run administratively by manual entry or simple copy-paste.

The command line can be started as follows: Start menu (Windows -Logo in the left corner of the taskbar) / All programs (scroll down) / Windows folder / Command line). Right-click on the command line icon and move the mouse cursor over the "More" entry in the small menu that appears. Another small window appears in which you can select the "Run as administrator" link.

The code raises the computer's Windows version to 21H1, as shown in the image below, and for adventurous returnees, the end result will be a Windows 19043 system, also known as the early 20H1 process.

Necessary precautions

It is probably wise to back up the test computer's operating system before attempting this script. Also, make sure you have a bootable USB flash drive from which you can restore the backup. This way, even if the worst happens and the updates make your computer unusable, you can restore the backup without too much fuss or wasting time. Just because it worked on my computer doesn't mean the test will work on someone else's computer. It is better to have backup and recovery tools, and it is better not to need than to have nowhere to recover!

activating Windows 10 21H1 19043

Caution: Be careful during the installation through the command line, because when it is finished, DO NOT send a warning that the installation is complete. Open the "About" window and check the build number. If 20H1 19043.782, you can close the command prompt window. Ready.

Quick Tip: If the installation seems to stop after a while, do not interrupt it, as a large file will install slowly. Patience. If you do not receive an error message, it means that it is installing in the background.


Step Three: Update Windows Feature Experience Pack:

If we've come this far by installing updates, we have a system that's right for us in every way, with only one update left, the Windows Feature Experience Pack update. This is an update that improves the reliability of the screen cutout, especially with applications that frequently use the clipboard.

Because this is not an official update, but a pre-release version for internal testing (Windows Insiders), it can be downloaded as a .cab file and installed from the command line using the method described above. (I installed and it works without errors ). Do the following:

Step one: Download the KB4601906.cab file from the link below, if available on your desktop, for easier access (or elsewhere).

Direct download links Windows Feature Experience Pack 120.2212.2020.0:

Windows10.0-KB4601906-x64.cab - 4.7 MB

Windows10.0-KB4601906-x86.cab - 3.8 MB

Step two: Run Command Prompt as administrator (Start menu / Windows folder / Command Prompt). Right-click on the command line icon and move the mouse cursor over the "More" entry in the small menu that appears. This will display another small window where you can select the "Run as administrator" link. Type the next command manually or by a simple copy-paste. Select the code with the mouse, then press Ctrl + C to copy. To paste, press Ctrl + V, then press Enter:

dism /online /add-package /packagepath:"cab_package_path"

In the command line above only the cab_package_path part needs to be rewritten depending on where you saved the downloaded "cab" file.

For example (if the cab file is in the download folder):

dism /online /add-package /packagepath:"C:/Users/John/Downloads/Windows10.0-KB4601906-x64.cab"

For example (if you downloaded the cab file to your desktop):

dism /online /add-package /packagepath:"C:/Users/John/Desktop/Windows10.0-KB4601906-x64.cab"

In the line of code above, the name "John" must be replaced with the name of the computer you entered during installation and is also displayed on the login screen.

Finally, press Enter. The command installs the KB4601906.cab update for 64-bit systems.
