How to import an exported profile in a semi-timely fashion

Start, Run, cmd  (OK)
The directory should be in the current profile
xcopy ..\oldprofilename /r /f /e /c /h /y         (while this is happening, start the next stuff)

copy the c:\profile\hkcu-user.reg to another reg name in case you need to undo any mistakes 
edit the copied reg file USING MICROSOFT WORD (Unicode if asked a question)

Control+H (Search and Replace)
s\\oldprofilename        with      s\\newprofilename       <------Double backslashes \\
1\\oldprofilename        with      1\\newprofilename       <------Those are (1)ones not lowercase L's

\\                       with      \                       <------From two \\ to a single \


Search for these and subkeys of these and remove all keys that start with the same text

[HKEY_CURRENT_USER\Software\Microsoft\Protected Storage System Provider] (i don't think there are any subkeys)

[HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\SessionInfo]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy]

[HKEY_CURRENT_USER\Software\Policies]

Save and exit

doubleclick the reg file you just saved

reboot
