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

• Fixed an issue where the PE Helper could apply the installation image to the wrong volume if it had been assigned drive letter C (#262, thanks @Real-MullaC for spotting)
• Fixed an issue where the WDS Helper Server would not export installation images to "install.wim" if they were named differently in WDS

New features

Preinstallation Environment Helper

• The WDS Helper server component now offers a web dashboard from which you can view logs, clear temporary files, and stop the server more easily. It also provides detailed information about the connection and the server:

• The ISO creator can now download and install the latest version of the Windows ADK (10.1.26100.2454) for you if it can't find it on your system:

Note

If it detects an existing ADK, however, it will use that as opposed to the latest one

• The default size of the ISO creator has been increased to 1280x720
• The PE Helper now adds the WinPE-StorageWMI packages to the Preinstallation Environment
• The command line can now be accessed from the main menu when you boot to the ISO file or when you start the boot image via WDS

Note

The command line is not available when you start the installation with HotInstall. The command line will also remind you that the environment will restart after 72 hours of uptime, This is because Windows PE, in order not to be used as a pirated version of Windows, imposes such a limitation

• A new command-line alias, netinit, now lets you initialize the networking stack and enable the firewall on demand; and other administration scripts are now included

Note

Network initialization will only work when you plug in your device via Ethernet, and if the Preinstallation Environment detects the network adapter. It will not work with wireless connections

DynaLog

• DynaLog now logs process IDs, which can help you tell multiple DISMTools processes apart more easily

Miscellaneous

• The following components were updated:

Component	Version in latest preview	New version
Markdig	0.41.2	0.41.3

• CODE: more LINQ queries have been introduced
• CODE: a new progress reporter module has been introduced. This is used by the ISO creator, but is expected to be used in other places as well

Bugfixes

• Fixed an issue where the popup mounted image picker would not show any results if the mounted image manager was already open
• Fixed an issue where connecting to a WDS server would fail if it didn't have a Pending Devices policy set up
• Fixed an issue where the WDS Helper client would not get the installation images in some cases

New features

Preinstallation Environment Helper

• HotInstall now uses the latest version of the DISM API
• HotInstall now creates a removal script that's launched on system startup to revert installation changes, in case the target system boots to the full Windows installation instead of the DISMTools PE:

• If drivers are applied to the boot image that clients will boot to with WDS, the WDS Helper client now applies such drivers to the target installation
• The WDS Helper client now informs about blocks the server will impose for 2 minutes for a specific device if any connections to the server errored out

Unattended answer files

• When configuring the wireless network, a link to go to your router's gateway page (typically 192.168.1.1) has been added. This lets you get the authentication technology of your router more easily if you don't know it:

• UnattendGen has been updated to the latest version
• The system component screen has been fully revamped:

This screen also provides documentation about a specific component, performing a Google search in its Web tab...

Bugfixes

• Fixed an issue in the update checker
• Fixed a deployment issue in the Theme Designer. It will let you load and save themes now instead of throwing an exception
• Fixed an issue where people could write to the console output
• Fixed an issue where DISM would never finish after edition servicing tasks due to a computer restart prompt. You should now see error code BC2, meaning that your computer needs to restart
• Fixed an issue where exceptions that aren't related to the DISM API were not being logged when running background processes
• External issue: Fixed an issue where background processes would abruptly stop when getting package information due to specific time representations (issue: jeffkl/ManagedDism#263; fix: jeffkl/ManagedDism#264)

New features

Preinstallation Environment Helper

• The restart message is now shown in a cleaner way:

• CODE: the PE Helper no longer requires dp_listdisk.dp to be present in order to list disks, as it's now generated automatically
• When starting up the DISMTools Preinstallation Environment, you will now see a menu from which you can choose the installation type:

• The WDS REST API now separates install images with folders with GUIDs as names
• Following the introduction of the WDS REST API in Preview 2, the DISMTools PE now includes the client component:

Note

Some notes to consider:

1. If the WDS server is configured to require administrator approval for unknown devices, make sure that a client is approved before running the client component. This component will check whether the client device is approved before continuing. If it isn't, the following message will be shown and the client will reboot after 5 seconds:

(How can that be possible? Well, because of Science. You can start NetInstall from DVD/USB media, and that reason alone mandates this check)

2. Expect some issues in the WDS Helper, since this is nothing but a technology preview, so please report feedback

Unattended answer files

• UnattendGen has been updated to the latest version
• You can now hide post-installation script windows when creating answer files:

Miscellaneous

• The following components were updated:

Component	Version in latest preview	New version
Managed DISM API	3.3.0	3.3.12

• You can now switch color themes for both dark and light modes in the personalization settings. To test the theme engine, the color scheme used in versions older than 0.5 has been reinstated, and has had a slight revamp in its color scheme to adapt it to both modes:

• You can now hide the clock in the project view
• DISM output is now saved to log files after operations are complete

Update details

Setting migration will be performed when you update to this version. These are the settings that will be affected:

Bugfixes

No issues were fixed in this release

New features

DynaLog

• DISMTools now includes a log viewer (DynaViewer)

Miscellaneous

• CODE: information dialogs are now able to disable the close button when getting information using Windows APIs

Removed features

• The restart dialog in the DISMTools Preinstallation Environment has been removed due to alleged "malware infections" (#246, thanks @MTTGamer for informing me)

Important

My commitment to keeping your PCs secure is still my number 1 priority. It just so happened that 20 vendors were flagging a simple application that shows a message, a timeout, and that returns an exit code, as "malware". It's a false positive, but I didn't take any chances, so I yanked it out of the program.

This will restore the old behavior in the PE Helper present during the 0.5 Series. Further changes will be made to this method to make it look like this dialog.

This issue shows the attack on open-source software developers. Every program I make does not have any malicious intent.

Bugfixes

• Fixed a migration issue where the color scheme would switch to dark, regardless of the preferred scheme you set in the past

New features

Theme Engine

• DISMTools now includes a theme designer and editor

Tip

Like DynaViewer, introduced in 0.7 Preview 1, this theme designer comes in 2 versions: one that uses .NET 4.8, and another one that uses .NET 2.0. The latter one makes it compatible with operating systems as old as Windows 98:

The theme designer running on Windows 98 and Me

When saving themes in Windows 9x, you will see an extra character at the beginning. This is because themes are saved with Unicode, and these operating systems use ASCII

Now, don't worry if things are getting too retro here. This will be the final tool compatible with old operating systems

Preinstallation Environment Helper

• Massive improvements were made to the DISMTools PE on network environments using PXE/Windows Deployment Services (WDS, #230)

As part of the network-based installation efforts (codenamed NetInstall), DISMTools includes 2 scripts designed for WDS:

• A preparation script (prepare_wds.ps1) that reinstates Windows Setup on a Windows PE image (note that the ADK present on the server must match in version to the boot image that is provided by the ISO file) and allows you to set it as a boot image as part of unicast or multicast AutoCast transmissions

Preparation script after setting up a boot image in WDS in a unicast transmission

Prepared boot image in BOOTMGR

Windows Setup in the prepared boot image

• A Web-based REST API (wdshelper_server.ps1) that can be used by an authorized client in DHCP scopes to allow basic interaction with the WDS server. These are the exposed APIs. Any additional APIs are declared in the source code of the script:

Here is a demonstration of some of these APIs:

Both scripts are available in the pxehelpers\wds folder of the ISO file. Yes, I know WDS is obsolete. I'll be looking at supporting additional network-based solutions

Important

The REST API script is designed to facilitate image testing with the DISMTools PE on the network and you can use them for any test deployments. For final deployments, an official boot image is still recommended. You can grab one from Windows installation media, or from the WDS preparation script

Miscellaneous

• CODE: the language engine, first introduced in HotInstall, has been ported to DISMTools
• CODE: information dialogs are now able to disable the close button when getting information using Windows APIs

Removed features

• 32-bit ARM support has been fully removed from the PE Helper

What's Changed

• DISMTools 0.7 Preview 2 by @CodingWonders in #256

Full Changelog: v0.7_pre_2551...v0.7_pre_2552

v0.7_250504

The first preview release of DISMTools 0.7 is now available, with new features and enhancements:

May the 4th be with you. Sorry, I couldn't resist. It had to happen for this release.

Bugfixes

• Fixed a minor issue where DynaLog timestamps would not use a common format for time

New features

Theme Engine

• The program now uses a theme engine that makes it easy for you to make your own themes

Note

No options have been added to the GUI to configure which theme to choose for dark and light modes, so you'll have to configure them from the INI or the Registry. The files are in an INI format, so they are easy to read and modify.

A theme designer is in the works to make it easier for you to make your themes.

DynaLog

• DISMTools now includes a log viewer (DynaViewer)

Tip

The program includes 2 versions of DynaViewer: a version that uses .NET 4.8, and another version that uses .NET 2.0. The latter one makes DynaViewer compatible with operating systems as old as Windows 98:
