Press Win+R on your keyboard to start a Run command box, and then type regedit.exe, Enter, open the registry editor.

If you are prompted for an administrator password or for confirmation, type your password, or click Yes.

IMPORTANT: If you modify the registry keys incorrectly, serious problems may occur. Therefore, make sure that you carefully follow these steps.

Navigate to the registry key: HKEY_CLASSES_ROOT\Excel.Sheet.12\shell\Open

Right-click the key, and then click Export. This step is to back up the registry key.

After you back up the key, follow these step:
  1. Change the value of the Open\command registry key.

    To do this, expand Command, double-click the Default entry, and then change the value to the following (with the quotes):

    Office 2010:
    "C:\Program Files\Microsoft Office\Office14\EXCEL.EXE" "%1"

    Office 2007:
    "C:\Program Files\Microsoft Office\Office12\EXCEL.EXE" "%1"

    Then, double-click the command key, move the cursor to the end of the string, and then replace /dde with "%1". If you are using Office 2007, replace /e with "%1".

  2. Rename Open\ddeexec.

    To do this, right-click ddeexec, click Rename, and then change it to a new name. For example, ddeexec2.

In the same way, repeat the above steps to back up and modify the HKEY_CLASSES_ROOT\Excel.Sheet.8\shell\Open registry key.

Now check if you open Excel files in separate windows.
