Disables the buttons on the File Types tab. As a result, users can view file type associations, but they cannot add, delete, or change them.
The File Types tab shows which programs open when you double-click a type of file. The file types are represented by their file name extension.
| Value | Meaning |
|---|---|
| 0 | Users can add, delete, and change file type associations. |
| 1 | Users cannot add, delete, or change file type associations. |
By disabling this tab, you can prevent malicious users from creating an association that starts a risky or destructive program. Also, users cannot create less productive associations, such as associating the .doc file type with Wordpad instead of Microsoft Word. This is a particular risk on multi-user systems, such as Terminal Services clients.
Note
Although this entry is located in the Policies\Explorer subkey, it is not associated with a Group Policy included in Windows 2000. You can create a policy by adding this entry to an Administrative Templates file. For information, see Creating custom .adm files in Windows 2000 Help.
This entry applies to all users of the computer. To set this entry for particular users, use NoFileAssociate in the HKCU subtree. If the settings of these entries conflict, the setting in HKCU overrides the setting in HKLM.
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
Tip
To see the File Types tab, in My Computer, from the Tools menu, click Folder Options, and then click the File Types tab.
