Office 2013 MRU Migiration

Hi,

We are about to roll out Office 2013 to our 400 odd user, I'm trying to get the MRU to migrate across from offcie 2010, however it doesn't migrate from the default install or our customized transform file.

i have found it does migrate the reg keys for them, from the office 2010 to office 2013 child(see below)

HKCU:\Software\Microsoft\Office\15.0\Word\File MRU

However Office 2013 does not read this location when logged in as a domain user it reads the File MRU from

HKCU:\Software\Microsoft\Office\15.0\Word\User MRU\AD_*Hash*\File MRU

I have created a script that can migrate the settings after office 2013 has opened a word document but will be extremely tedious for our 400 users

Is there a way to re-point office 2013 to look a the first Reg key location for its file MRU?

or what is the sha512 hash generated from so we can run a script at the end of installation to copy the keys into the correct location.

Thanks in advance
