314. File Associations are Greyed Out
-----
NoFileAssociate
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer
Data type Range Default value
REG_DWORD 0 | 1 1 (Terminal Services systems)
0 (All other Windows 2000 systems)
Description
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 a type of file is
double-clicked. 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.
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 takes precedence over 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. ]]
