modified to me means the changes I make to have xp function to my way
1. disabling or making manual some services
2. deleting extraneous files
3. disabling messenger and outlook express
4. changing registry to have system shutdown programs quicker, clearing page file at shutdown, bypassing login page, disabling simple file sharing, increasing icon cache, installing the recovery console as a boot option, bypassing the admin password in the recovery console, activating the set commands in the recovery console, and a few other things.
