Open a new workbook and give save command then SAVE AS window will appear.
In that SAVE AS window see the right corner for TOOLS option. Clik the drop
down list of TOOLS option then you can find an option that is GENERAL OPTION.
Clik that general option then you can find the check box enabled to ALWAYS
CREATE A BACKUP. Uncheck it then your problem will getting resolved.
