Disabling generative AI Assistant in Adobe Acrobat Reader DC via the Windows registry
Tested and validated on Adobe Acrobat Reader DC v2026.001.21662 (Windows 11)
1. Context and privacy warning
Since v26, Adobe Acrobat Reader DC includes a generative AI Assistant. When a PDF is opened, the assistant automatically suggests contextual questions (e.g. "Why is this information important?").
⚠️ Warning — data transfer to Adobe
- If the AI Assistant is enabled and the user interacts with it, the content of the PDF is sent to Adobe's AI servers. This applies to any open document, including confidential documents or documents subject to legal obligations (NDAs, personal data, professional secrecy, etc.).
- It may be recommended to disable this feature in some professional environments.
Below are two registry-based methods, depending on whether you want a hard lockdown or just a default-off setting.
2. METHOD 1 - Global lockdown (machine level)
This method completely blocks the AI Assistant for all users of the machine. Users cannot re-enable it from the preferences (the Generative AI category no longer appears in the menu).
2.1. Registry key
| Parameter | Value |
|---|---|
| Path | HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown |
| Name | bEnableGentech |
| Type | DWORD (32-bit) |
| Value | 0 (disabled) 1 (enabled) |
2.2. Via PowerShell (for deployment)
$path = "HKLM:\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown"
if (!(Test-Path $path)) { New-Item -Path $path -Force | Out-Null }
New-ItemProperty -Path $path -Name "bEnableGentech" -Value 0 -PropertyType DWORD -Force2.3. Effect on the user interface
- The Generative AI category disappears from Menu > Preferences…
- The Ask AI Assistant button is no longer displayed in the toolbar
- Users cannot re-enable the feature
3. METHOD 2 - Disabled by default (user level)
This method disables the AI by default but lets the user re-enable it from the Acrobat preferences.
3.1. Registry key
| Parameter | Value |
|---|---|
| Path | HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\DC\Gentech |
| Name | bConsentProvided |
| Type | DWORD (32-bit) |
| Value | 0 (disabled) 1 (enabled) |
3.2. Via PowerShell
This script modifies the user preference:
$path="HKCU:\Software\Adobe\Adobe Acrobat\DC\Gentech"
if (!(Test-Path $path)) { New-Item -Path $path -Force | Out-Null }
New-ItemProperty -Path $path -Name "bConsentProvided" -Value 0 -PropertyType DWORD -Force3.3. Effect on the user interface
- The Generative AI category remains visible in Menu > Preferences…
- Users can re-enable the AI by checking: Menu > Preferences... > Generative AI → check Enable generative AI features in Acrobat
Hope this helps other admins managing Acrobat Reader in corporate environments.
