In some cases, we get an "Open With" box while accessing any executable.
This problem occurs if the .exe file association in the registry is corrupt. This behavior is generally caused by viruses.
Click Start, Run and type "regedit"
If Registry Editor opens successfully, then navigate to the following key:
HKEY_CLASSES_ROOT \ exefile \ shell \ open \ command
Double-click the (Default) value in the right pane
Delete the current value data, and then type:
In the right-pane, set (default) to exefile
Exit the Registry Editor.
If registry editor does not open, then follow the steps below:

Click on New
Provide the File Extension as "EXE"
click on Advanced
In the drop down menu " Associated File Type", choose "Application"
Click on OK.
