If you want to allow almost everything, you can try giving your account administrator priveledges. Do this by loggin in to the administrator account, picking the add user acount option from the welcome screen, selecting the add/delete users option from the account screen, then picking your main account. From that menu, pick "change account type", and select "administrator". After that, your main account will be an admin and you might have less permission issues.
But if you really want to nuke the permissions stuff, you can disable UAC (User Account Control). Do this as above from your administrator account, but from the main account management screen, select the "disable User Account Control" option (I think that's what the option is called), and I think it should behave like XP.
