DISMTools 0.7.2 is now available as a stable version, with new features and enhancements:

File hashes

File	Name	Hash (SHA256)
Installer	dt_setup.exe	3AB811B201889DB9A1B46735B6E81581FFE3027B5328815706ECF91D2A94FEA0

Important

If you use Windows Defender, it may incorrectly flag this version as malware. SmartScreen may also do this. Don't worry; this is safe to download and use.

This AV solution flags this program because it lacks code-signing certificates, which are quite expensive (as of January 2025, 660 and 864 dollars for 3 years of SV and EV certificates, respectively, from Comodo).

If you use other antivirus solutions, you will not see this problem. Learn more here

Note

Those using the Windows Utility to install apps can now install the stable release of DISMTools from there

Overall changes

Note

This will show the bugfixes of all preview versions. To view them, expand a section

Preview 1

• Fixed some issues regarding absolute paths in some cases (#300, thanks @jekovcar)

Preview 2

• Fixed an issue where YouTube videos in the DISMTools Tour would not show with video player error 153

Preview 3

• Fixed an issue where HotInstall would fail to prepare a computer if it already had BOOTMGR legacy view settings configured
• Fixed a crash when opening the popup mounted image picker in some cases

Preview 4

• When picking a starter script using the predefined collection, language highlighting is correctly selected now
• ADK detection has been refactored in both the main program and the PE Helper to detect ADK kits roots, as opposed to a registry value that is no longer added by ADK installers (thanks rayman95 on the My Digital Life forums for spotting)
• Certain windows that cause freezes when the program is closed are now closed automatically

New features

Preinstallation Environment Helper

• HotInstall has received DynaLog logging
• The PE Helper will now call OSCDIMG more times if it fails to create the ISO file
• The Sysprep Preparation Tool has been updated to version 0.7.2
• The PE Helper now introduces a computer inventory framework that lets you view information about your system, for issue reporting
• You can now access PXE Helper Servers more quickly from the Tools menu:

• Notes are now included for the FOG Helper Server on UNIX
• The FOG Helper Server for UNIX now checks presence of FOG and MariaDB systemd service units
• DISMTools will now warn you when you create ISO files with UEFI CA 2023 support on a system that does not offer such support:

• The PE Helper now adds the WDS Tools optional component to the Preinstallation Environment
• The image capture script in the DISMTools Preinstallation Environment now lets you launch the Driver Installation Module to load disk controllers, and the WDS image capture wizard to capture your installations for a WDS instance:

• Several improvements were made to the WDS Helper:
  • The WDS Helper now displays a warning when it's loaded on non-PXE environments:
    
  • The WDS Helper can now get the IP addresses of the PXE client and the PXE server. You can default to using the server's IP address and the default port as well:
    
  • The WDS Helper now validates more information when authenticating with the server

Unattended answer file features

• UnattendGen has been updated to the latest version
• Self-contained copies of UnattendGen that are older or newer than the expected version will now be removed automatically
• The Starter Script format now contains name and description fields
• You can now preview starter scripts before loading them with the new Starter Script browser:

• The following starter scripts are affected by this version:

Starter Script	Stage	State	Changes (if modified)
Set Quick Machine Recovery Settings	During System Configuration	Modified	Value checking has been added1
Enable Verbose Status Messages	During System Configuration	New
Disable Windows Notification Sources	When users log on for the first time	Modified	Copilot (APPX package) has been added to the blocklist2
Configure folders for Git integration	When the first user logs on	New
Set a custom wallpaper	When the first user logs on	Modified	Wallpaper path has been moved to a variable
All remaining scripts	Any stage	Modified	Added name and description fields

¹ Boolean values under 0 are now 0 and ones over 1 are now 1. Negative integer values are now automatically converted to positive values.
² Because Copilot is block-listed with its AppX package name, modifications to this starter script may be done in the future in case that package name changes. In the event of a package name change caused by a newer version of Copilot, any existing answer files with old versions of this script may no longer disable Copilot notifications.

• A product key can now be determined automatically by the wizard based on the edition of the mounted Windows image:

Note

Edition detection should work correctly for most Windows images as they use standard edition IDs such as Professional or ProfessionalWorkstation. Otherwise, you will still be able to specify an edition manually, or a custom product key that works with said Windows image. The generic product keys work with Windows 11. They may also work with Windows 10.

Image Tasks

• Web Search engines are now configurable:

• Feature and capability image information dialogs now have links to search for specific items online, using your preferred search engine

DynaLog

Note

Tinted color themes are available for red, green, orange and purple colors in both light and dark modes. Those who prefer a more minimalist look can also opt for black and white color themes

• Inno Setup has been updated to version 6.6. With this change, you will now see installers in a dark theme, if you had configured your system accordingly:

• The RTF version of the GPLv3 license is now used
• The installer window size has been increased
• The popup mounted image picker now loads at the center of the parent window to avoid showing either partially or out of screen bounds
• The following libraries and components have been updated:

Important

If you use Windows Defender, it may incorrectly flag this version as malware. SmartScreen may also do this. Don't worry; this is safe to download and use.

This AV solution flags this program because it lacks code-signing certificates, which are quite expensive (as of January 2025, 660 and 864 dollars for 3 years of SV and EV certificates, respectively, from Comodo).

If you use other antivirus solutions, you will not see this problem. Learn more here

Bugfixes

• The DNS address syntax parser of the Active Directory domain join wizard now parses scoped IPv6 addresses correctly

New features

Preinstallation Environment Helper

• COMMAND-LINE ONLY: the PE Helper now supports external temporary directories
• The WDS Helper now supports cleaning up files by independent session GUIDs

Unattended answer file features

• The following starter scripts have been added to system configuration and first user logon stages:

Starter Script	Stage
Skip First Logon Animation (OOBE FLA)	During system configuration
Personalize user environment1	When first user logs on

¹ The starter script can also be used whenever users log on for the first time as a means to configure common personalization settings for all users if run on multi-user systems

System Service Manager

• The service manager now disables the Delayed Start field when a service start type is not Automatic
• The service manager now exports current service information of the target image to the user's desktop, and also allows modifications of the following fields:
  • Start Type
  • Delayed Start

Note

The service backup process will export the HKLM\SYSTEM\ControlSet<nnn>\Services key of the target image to your desktop as a REG file. This file can then be imported as a means to restore previous service information if service modifications didn't go as planned. To restore previous service information, with the image mounted:

1. Load the SYSTEM hive using the image registry control panel, or the reg load command if you prefer a more manual approach
2. Double-click the REG file and import it
3. Unload the SYSTEM hive and commit the image

Note that, while importing, you may encounter the following error:

This is normal as it exported the entirety of the key, including keys and values that you may not be able to modify on your own without the necessary privileges. However, the remainder of the keys will still be imported successfully.

Image Tasks

• A new tool has been added to view the environment variables of the Windows image

Important

Starting from this release, no more canary installers will be made until further notice. This is because of sudden issues with OpenSSL that prevent the installers from being shipped to the repository. To prevent flooding my inbox with "Run failed" emails, I've disabled the workflow. I might go back and revisit this workflow, but I'm not going to spend an entire day inspecting the problem and fixing it. From now on, you'll have to build the installers from the source code.
