The hardest part was recovering my Outlook Profile -- i was not looking forward to re-entering all of the credentials for my various email accounts. Windows moved the old windows to a new folder "Windows.Old" found my old registry hive, and was able to extract the Outlook Profile.
Here's the steps. Thanks to JRich from Mass General for blog post that pointed me in the right direction!!
In Powershell, run as the administrator:
1. Use the REG command to load the "old hive" into your registry under the HK Local Machine
reg load 'HKLM\_OldOutlook' "C:\Windows.old\Users\riuliano\NTUSER.DAT"
2. Open RegEdit navigate to Outlook, i.e.
3. In Regedit, right-click on "Profiles" and Export the file
4. Edit the exported profile file, and replace "Hkey_Local_Machine\_OldOutlook" with "HKey_Current_User\". Save the file
5. Back in RegEdit, Import the "reg" file you just edited.
6. Back in Powershell, remove the registry key and garbage collect.
reg unload hklm\OldOutlook
BTW, if you want to see what the director looks like in powershell, you can create a virtual directory of the old hive:
New-PSDrive -Name OldOutlook -PSProvider Registry -Root "HKLM\_OldOutlook"
then you can "cd OldOutlook:"
and get-item and value. I'm sure i could have looped through and copied each profile key from the old hive to the new hive. Export seemed much simpler, though.
Remember to remove the PSDrive:
