+## HTA applications report Script error after upgrading to ADK for Windows 11, version 22H2
+After you updated your MDT boot image to [ADK for Windows 11, version 22H2](/windows-hardware/get-started/adk-install), HTA applications stop working and a message box is displayed: Script Error - An error has occured in the script on this page.
+
+HTA applications relies on MSHTML and starting Windows 11, version 22H2, the default legacy scripting engine was changed.
+
+To workaround the issue, you need to add the following registry value in WinPE: 
+ ``` 
+ reg.exe add "HKLM\Software\Microsoft\Internet Explorer\Main" /t REG_DWORD /v JscriptReplacement /d 0 /f
+ ```
+To enable this change in MDT, we recommand you to backup the following file C:\Program Files\Microsoft Deployment Toolkit\Templates\Unattend_PE_x64.xml and to modify it like this:
+ ``` <?xml version="1.0" encoding="utf-8"?>
+<unattend xmlns="urn:schemas-microsoft-com:unattend">
+    <settings pass="windowsPE">
+        <component name="Microsoft-Windows-Setup" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State">

+                    <Order>1</Order>
+                    <Path>reg.exe add "HKLM\Software\Microsoft\Internet Explorer\Main" /t REG_DWORD /v JscriptReplacement /d 0 /f</Path>
+                </RunSynchronousCommand>
+                <RunSynchronousCommand wcm:action="add">
+                    <Description>Lite Touch PE</Description>
+                    <Order>2</Order>
+                    <Path>wscript.exe X:\Deploy\Scripts\LiteTouch.wsf</Path>
+                </RunSynchronousCommand>
+            </RunSynchronous>
+        </component>
+    </settings>
+</unattend>
+  ```
+After saving the changes, you will need to completely regenerate the boot images.
