From the xl2007 help file...

"If you want a macro to be available whenever you use Excel, select Personal Macro Workbook.
When you select Personal Macro Workbook, Excel creates a hidden personal macro workbook
(Personal.xlsb) if it does not already exist, and saves the macro in this workbook.
In Windows Vista, this workbook is saved in the
C:\Users\user name\AppData\Local\Microsoft\Excel\XLStart folder.
In Microsoft Windows XP, this workbook is saved in the
C:\Documents and Settings\user name\Application Data\Microsoft\Excel\XLStart folder.
Workbooks in the XLStart folder are opened automatically whenever Excel starts."

In order to copy macros from previous vesions of Excel and for
purposes of backing up the file, I need to know where the Personal
workbook is stored. I've been unable to find it using regulare search
methods.
