How to take ownership of a file or a folder in Windows XPPrerequisitesLog on as an administrator
You must be logged on to Windows as an administrator in order to change security permissions for a file or a folder. If the computer is your personal computer, you are likely already logged on with an administrator account. If the computer is part of a network at work, you might have to ask the system administrator for help. To verify that you are logged on to Windows with a user account that is a computer administrator, visit the following Microsoft Web site:
