Running macro automatically on excel startup

If you record a macro and save it using the name "Auto_Open", the macro will run whenever you open the workbook that contains the macro.
If you want to save the macro with a particular workbook, open that workbook first.
On the Tools menu, point to Macro, and then click Record New Macro.
In the Macro name box, type Auto_Open.
In the Store macro in box, specify where to save the macro:
To save the macro in the current workbook, choose This Workbook.
To create a new workbook to save the macro in, choose New Workbook.
To save the macro in a hidden workbook that is automatically loaded when you start Excel, choose Personal Macro Workbook.
Note If you choose Personal Macro Workbook, Excel will create and save the macro in a hidden workbook named Personal.xls (if Personal.xls doesn't already exist). In Windows 2000, Personal.xls is saved in the C:\Documents and Settings\username\Application Data\Microsoft\Excel\XLStart folder so that it will be loaded automatically whenever Excel starts. If you want the macro you record and save in Personal.xls to act on a particular workbook, you must also save that workbook in the XLStart folder so that it will also be opened when Excel starts.
Click OK, and then perform the actions you want to record.
On the Stop Recording toolbar, click the Stop Recording button.
If you chose to save the macro in This Workbook or New Workbook in step 4, make sure to save or move the workbook into one of the XLStart folders.
