In Microsoft Windows 2000 Service Pack 3, changes were made to the Hypertext Templates (HTT) feature. These changes help prevent potentially unsafe content from running when you open a folder on your local computer or on your local area network (LAN). To run .htt files on Windows 2000 Service Pack 3 or later versions, you must turn on Web view functionality for local or network folders in Windows Explorer, or you must make changes to the registry.
Specifically, you must add the RevertWebViewSecurity registry entry to the registry. This entry has a value of 1. This value lets Windows display the Web view templates and customizations that do not have an MD5 hash that is registered with Windows. (The MD5 hash is also known as an MD5 message-digest.)
Note These Web view templates and customizations are stored in the Folder.htt file. The Folder.htt is a HyperText template file.
After you change the registry, you receive a security message only for Web view templates or customizations that contain potentially unsafe scripting.
However, after you install Windows 2000 Service Pack 4 , you receive a security message every time that you try to use the HTT feature to customize folders. This problem occurs even if you have added the RevertWebViewSecurity registry entry to the registry.
After you apply this hotfix, add the
RevertWebViewSecurityregistry entry to the registry. This entry has a value of 1. This value lets Windows display the Web View templates and customizations that do not have an MD5 hash that is registered with Windows. Add following registry values under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer:
Value name: RevertWebViewSecurity
Value type: DWORD
Value data: 1
