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

If you use Previews 1 or 2, start the update process by going to the About dialog (by clicking "PREVIEW")

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:

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)

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