Windows 2000 SP3, Windows XP SP1, and Windows Server 2003 do not display Web view templates (Folder.htt) from earlier versions of Windows, or HTML customizations of Web view templates for local or network folders. These products turn off this feature to help prevent potentially unsafe content from running when you open a folder on your local computer or on your LAN.
NOTE: Web view templates for some registered shell extensions may still display.
Setting the following registry Value Names, all REG_DWORD data types, to a data value of 1, at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer, will restore Web view functionality:
|Value Name||D E S C R I P I O N|
|AllowLegacyWebView||Permits Windows to display the Web view templates that have an MD5 hash registered with Windows. Only Windows 2000 Web view templates and templates for certain shell extensions have an MD5 hash registered.|
|AllowUnhashedWebView||Permits Windows to display the Web view templates that do not have an MD5 hash registered. You will receive a security warning, but pressing Yes will register the template and cease to warn when using it.|
|RevertWebViewSecurity||Permits Windows to display the Web view templates that are NOT registered. This is the same behavior as Windows XP prior to SP1 and Windows 2000 prior to SP3. This setting also requires setting AllowLegacyWebView.|
Since you view settings are cached, reset all the folder settings in Windows Explorer:
1. Use the Tools menu to open Folder Options.
2. On the View tab, press Reset All Folders.
3. Restart you computer and re-apply whatever View settings you desire.
