There's less need to jump through all these hoops if you have physical access to a PC with enabled USB ports. For example: you could boot from the USB device and access the local storage if it's not encrypted.

EDIT: I meant to say "if you have physical access without Bitlocker enabled". Bitlocker is protecting the contents of the storage, if you can bypass the lockscreen on a Bitlocker protected computer you've evaded this protection.
