When downloading files using Internet Explorer, you may see the Open/Save confirmation box (as shown below) for certain file types. If you uncheck the Always ask before opening this type of file checkbox, the preference is saved in the user part of the registry. Also, the configuration is stored in a separate registry value for each file type.
Here is how to reset the Open/Save choice for a specific file type or all file types in Internet Explorer in Windows XP/Vista, Outlook Express and Windows Mail.

EXAMPLE
For example, if you download an Word 2003 file from a Web site and uncheck the above option. the registry is updated with the following registry entry:
Value name: Word.Document.8
Value type: REG_NONE
Where Word.Document.8 is the ProgID for .doc file types. Examples of other ProgIDs are txtfile, WinZip, xmlfile, wmvfile and so forth.
WINDOWS XP
To reset the Always ask before opening this type of file choice in Windows XP, use these steps:
1. Click Start, Run and type CONTROL FOLDERS
2. Select File Types tab
3. Select the file type from the list for which you wish to reset the Open/Save as option
4. Click Advanced
5. Enable the option named Confirm open after download
6. Click OK.

WINDOWS VISTA
As Windows Vista does not have the File Types tab in the Folder Options applet, you need to edit the registry in order to reset the Open/Save choice made earlier in Internet Explorer.
1. Click Start, type Regedit.exe and press ENTER
2. Navigate to the following branch:
3. In the right-pane, right-click on the appropriate entry and choose Delete
4. Exit the Registry Editor.
OUTLOOK EXPRESS / WINDOWS MAIL
Outlook Express and Windows Mail store the Always ask before opening this type of file choice in a different registry key. It’s here:
RESETTING THE OPTION FOR ALL FILE TYPES
To reset the Always ask before opening this type of file choice for ALL file types, you don’t even have to open Regedit.exe. You can accomplish this using the Reg.exe command-line tool.
For Internet Explorer in Windows XP and Windows Vista
Open a Command Prompt window (CMD.EXE) and type:
For Outlook Express & Windows Mail
Note: To prevent formatting or syntax errors, copy the text from the text box above and paste it exactly in the Command Prompt window.

you are awesome. I spent all day trying to undo. work just like you said. Thanks a million, PTL 4 U!!!!!
AWESOME!!! That worked, I had resolved the issue one other time but forgot how to do it. After many searches online, this was quick and easy. Thanks for the help and for posting this!
Thank you so much. I was cracking my head because of this issue.
Great. I found the solutions from this site after long time.
It worked!! Been trying to fix this problem for 6 months!! Thank you so much!!
What if there’s no “attachmentexecute” registry key? Is there another way that this issue can be resolved if you don’t have this key?
Thank you so much. This was very helpful!
I love downloading custom content for my Sims 2. The information you shared with us on how to reset the Open/Save choice allowed me to start downloading again. Thank you very much for sharing this information with us. I looked everywhere on how to solve this problem. Every site gave me information on how to solve this problem for Windows XP. I really like the tip you gave me for resetting the option for all file types.
This is one of the most annoying features of Vista, an OS I otherwise absolutely love, and you have fixed my problem.
I think it’s a backwards step by MS to remove the ability to undo/redo something this significant from the UI. It was present in XP (albeit you had to know where to go to change it) but to make you have to delve into the registry in Vista is just wrong.
Anyhow, thanks for this – am as pleased as punch!
great stuff – fixed a problem that was really irritating me badly. Thank-you.
