HKCU and HKU registry records
This is a bonehead question about the registry.
Is the HKCU hive (if that's the right term) dynamically built from HKU\S-1-5-21-... records every time a user logged on?
I want to make some changes to the registry records of product - copying hundreds of configuration records from an old release set to a new release set. I'm very aware that this may be a big blunder. The records are in both HKCU and my HKU. If I change the HKCU registry records and am blown out of the water, will logging off and back on get me back to the unchanged HKU copy, or does Windows keep the two sets in sync?
I could (and probably will) export all the records I intend to change, but I could also just uninstall and reinstall the program if it fails to run. But I'm more worried about changing something I did not intend to change - something else in the HKCU hive.
I will take a complete backup of my system before doing any of this and plan on doing a system restore if I really hose things over, but I would rather have a quicker and more simple recovery.
