Reset Save/Open Option in Internet Explorer

When you are using Internet explorer to download something you get the option to open the file or save the file. You can select what you want to do. If you choose to save the file you will be asked to select a location for it and if you choose to open, the file will be in the temporary folder and it will be opened when its completely downloaded. But while doing this you will see a option on the File Download dialog box that says 'Always ask before opening this type of file'
like this

If you uncheck this box then internet explorer will use the option you select after that as a default action whenever you downloaded that type of file. Means if you are downloading a zip file and you uncheck the box and click the save action and save the file somewhere. Then after that when you want to download any zip file, internet explorer will save that file directly to the location you selected earlier without asking you, if you want to open the file or save it. If you want to get this option back then you need to edit the registry. Backup the registry before you do this.

--- Now go to registry by typing regedit in the run box.

--- Then look for the key
HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046}

--- Now in the right hand pane look for the entry you want to delete the setting for in our case its the zip file.

--- Delete that entry and exit the registry.

--- If you want to get the option to save or open the file while downloading any files then you have to delete all the entries present there.

Or you can download the registry file given below and double click on it. Download this file Reset save/open option in IE double click on it and add it to your registry.

That's it you will have the option to save or to open the file you want while downloading.
