Setting HKCU for all existing users

[Fuzzy_Bunny_Slippers]

I have been trying to set up a program that needs to add registry information to HKCU for about 500 machines, however many users on each machine, and most will not have administrative rights.

I created an MSI package which can run with System access but it doesn't add the registry keys for all users to HKCU. I was thinking about HKU but that seems to only be for new local users.

What can I do to set for each user when they next log on, like a run once, but it has to be runable by limited users.

Thanks,

have you tried adding the reg file in a login script?
