This question already has an answer here:
I need to connect my machine to a new domain soon. When I do so a new user profile will be created and I would like to copy all the settings/data from the old profile to the new one. This is a local profile only (no roaming). Running Windows 7 Enterprise 64 bit.
I found this previous question on the same topic, it however only seems to address Windows XP and the solutions do not seem to apply to Win7.
