I've had the "Uninstall or Change a Program" Control Panel using the
Contacts folder template (with Import and Export [contacts] in the Toolbar).
This might not correspond to your problem, but I think you are having
template problems, none-the-less. Of course, there is no way to change the
"folder" template for "Uninstall or Change a Program".
To reset the folder type, even pretend ones like "Uninstall or Change a
Program", for a Windows folder (that is, when it's showing inappropriate
tasks in the toolbar), you'll have to do this:
In the Registry Editor, go to
HKEY_CURRENT_USER\Software\Classes\Local
Settings\Software\Microsoft\Windows\Shell\BagMRU
Then right-click on the key BagMRU, in the left-hand pane, and choose
delete. Then go to
HKEY_CURRENT_USER\Software\Classes\Local
Settings\Software\Microsoft\Windows\Shell\Bags
Right-click on the key Bags, in the left-hand pane, and choose delete.
Log off and log back on to Windows to re-create the keys (done
automatically), and start anew. This will reset all your folders to the
default templates.
