Opening Excel File without Open Save Cancel Dialog Box

Why a security risk?

The following image shows the Open-Save-Cancel dialog box shown by Internet Explorer when trying to download a file.

The Open-Save-Cancel dialog
As explained above, allowing a file to open or run on your system without confirmation that you really want it to is a security risk. Some files contains viruses, and some site will try to download harmful files to your machine without prompting you. It is therefore not recommended that you allow file download without the download prompt so that users have to verify the file and its source can be verified before downloading or running it. Disabling the download dialog box makes the system vulnerable to viruses, Trojans and hackers who may silently affect your system.

  5. Uncheck Confirm open after download.
  6. Select the third option - Browse in same window - to view the Excel file in Internet Explorer without starting Microsoft Excel standalone.
