Convert Win10 LTSC custom image to iso or wim

Windows 10 LTSC (Long-Term Servicing Channel) is a specialized edition of Windows 10 that is designed for devices and systems that require stability and long-term support. It doesn't receive feature updates like the regular Windows 10 editions, but it does receive security updates for a longer period of time.

If you have a custom image of Windows 10 LTSC and you want to convert it to an ISO or WIM file, you can do so using the Deployment Image Servicing and Management (DISM) tool. This tool is built into Windows and allows you to manage and modify Windows images.

Converting Win10 LTSC Custom Image to ISO

To convert your Win10 LTSC custom image to an ISO file, follow these steps:

1. Open Command Prompt as an administrator. You can do this by right-clicking on the Start button and selecting "Command Prompt (Admin)".
2. Navigate to the folder where your custom image is located. For example, if your custom image is in the "C:\CustomImage" folder, type cd C:\CustomImage and press Enter.
3. Run the following command to generate an ISO file from your custom image:
   dism /Get-WimInfo /WimFile:install.wim
4. Note down the index number of the image you want to convert to an ISO. It will be displayed in the output of the previous command.
5. Run the following command to convert the image to an ISO file:
   dism /Export-Image /SourceImageFile:install.wim /SourceIndex:1 /DestinationImageFile:install.iso /Compress:Max /CheckIntegrity
   Replace "install.wim" with the name of your custom image file and replace "install.iso" with the desired name for your ISO file.
6. Wait for the conversion process to complete. This may take some time depending on the size of your custom image.
7. Once the conversion is finished, you will find the ISO file in the same folder as your custom image.

Converting Win10 LTSC Custom Image to WIM

If you prefer to convert your Win10 LTSC custom image to a WIM file instead, you can use the same DISM tool. Here's how:

1. Open Command Prompt as an administrator.
2. Navigate to the folder where your custom image is located.
3. Run the following command to convert the image to a WIM file:
   dism /Split-Image /ImageFile:install.wim /SWMFile:install.swm /FileSize:4096
   Replace "install.wim" with the name of your custom image file and replace "install.swm" with the desired name for your WIM file.
4. Wait for the splitting process to complete. This may take some time depending on the size of your custom image.
5. Once the splitting is finished, you will find the WIM file in the same folder as your custom image.

By following these steps, you can easily convert your Win10 LTSC custom image to an ISO or WIM file using the DISM tool. This can be useful for creating backup copies of your custom image or for deploying the image to multiple devices.
