Today we discovered Adobe Express Photos installed on a number of our corporate computers. Nobody in IT approved or deployed it, and the affected users did not intentionally install it.

It arrived automatically through the Acrobat update mechanism.

The app then took over the Windows screenshot shortcuts, including Print Screen and Win + Shift + S. It also changed the clipboard behaviour: screenshots pasted into Outlook Classic are now added as file attachments instead of being inserted into the email body.

Adobe’s own enterprise documentation confirms that Express Photos is a separate Windows application, but that it can be installed automatically through Acrobat updates.

Uninstalling it is not enough. According to Adobe, it may be installed "for your convenience" again during the next Acrobat update unless administrators deploy a registry policy specifically to block it:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown

bDisableHarmonyInstallationFeature = 1

So Adobe used the automatic updater for a PDF application to install a different product, changed a native Windows workflow, caused problems in another application, and made administrators opt out through the registry to stop it coming back.

This is real asshole behaviour.
