'+1 on that
...well, I actually had some success by tweaking my original export from HKEY_CURRENT_USER and re-importing it into HKU\uuid :
from :
Computer\HKEY_CURRENT_USER\Software\Sysinternals\Process Explorer\ColumnSet0
to HKEY_USERS\S-1-5-21-1549993580-1326954523-1790782792-1003\Software\Sysinternals\Process Explorer\ColumnSet0
Also had to change NumColumnSets (mind the off-by-1 -> it starts at 0 for the first saved column set)
