Ok, I have thrown a listing together of the keys needed for this.
WARNING- using these registry entries will be at your own risk. Do not use if you dont feel comfortable editing the registry.
Additional steps will come later on.
BLENDER SHOULD BE CLOSED TO PERFORM THESE UPDATES. Failure to close blender prior to modifications may result in strange behavior.
I recommend one edit at a time, test, then do the next.
All entries are directed to the X64 install of blender 2.70 default path for Windows.
To change non-default just update C:\\Program Files\\Blender Foundation\\Blender\\ to your path. Dont forget the double \\.
I will provide LIMITED assistance if you incorrectly perform the changes.
Double check your registry entries for the below before adding them. Duplicating entries can cause conflicts.
Code:

To import settings and addons, copy and paste the numerical folder of your previous version in C:\Users\
YOURUSERNAME\AppData\Roaming\Blender Foundation\Blender
then just rename it to 2.70 and all settings will import.
Note:New layouts may result in a different look with your themes. You may need to modify your theme.
