Permanently Remove Check Mark In Always Use This Program---
The following trick worked in W98SE to permanently remove the check mark in the "Always use the selected program to open this kind of file".

I messed up tonight and associated a .dsc file(dscrypt) with Adobe Reader.

I couldn't get it to disassociate from AR with the Default Programs, so I found the registry entry and deleted it with a backup, just in case. All is well now but I want to get that check default check mark out before I mess up again sometime.


"This tweak permanently unchecks the "Always use this program to open this file type" checkbox on the "Open With" dialog
box, when opening a non-associated file type. Run Regedit and go to:


Add %2 to the current "Default" value as shown here:

C:\WINDOWS\Rundll32.exe Shell32.dll,OpenAs_RunDLL %1 %2

Close Regedit and press F5 to refresh the Desktop."

If you have a problem associating a file after this tweak go to this link for important info: (#8 and #14 Response)

I found this same registry key in Vista and added the %2 and restarted but it didn't have any effect on the check mark.

Does anybody have a solution?

Found this.


Method A:

1. Open regedit and goto:


2. In right-side pane, change value of "Default" key to as following:

%SystemRoot%\system32\rundll32.exe %SystemRoot%\system32\shell32.dll,OpenAs_RunDLL %1 %2

NOTE: We have only appended %2 at last of default value. You can use any number from 2-9.
Verified on my Vista x64 machine.
