After performing the changes i need in the registry, i have to reboot in order to activate them.
Normaly when i change the display settings, i have the 'apply' option, which activates the changes without the need of booting. How can i do this?
With API, NT commands? Keys in the registry? ...
Thanks for any advice!!

Yes you do, unless the changes only impact your application and not the system in that case I would re-initialize the configuration within your application. If you are going to impact the system you will need to either re-boot or re-logon.
With out knowing more about what it is your goals are its hard to determine a suitable answer.

Hope this helps

Thank You for the reply, i'll try to give you more info.
I use 2 graphic cards. The second graphic card should be active only for certain users, (wich will use a special device on it). Searching for a way to enable-disable the second graphic card in a way that the user won't notice, i made a copy of the whole registry using 1 card and another copy of the registry when i enable the second card. I compared them with a compare software an i obtained in wich keys there where changes. Knowing this i made two profiles, one with this keys using 1 card, and other with the same keys using 2 cards. Then i installed the keys in start up depending on the particular user needs. Once the keys where installed i checked in the 'Display Settings' but i saw no changes. Then i made a reboot and the new settings where there. I was glad i found the right keys (was lots of work), but i can not prompt the user after login in to perform a reboot in order for the changes to take effect (this is KO). And second i needed to change 15 keys...pretty dangerous when i do not know exactly what else am i changing.
I use Windows 2000 Prof. in a DELL 530 Workstation, 512 RAM, 2.2 MHz,...and of course 2 graphic cards.
Any ideas?

i wouldve thought that this configuration would be sorted out by a driver at start up so maybe you shouuld have a look at which drivers are involved and if there is a way to restart the drivers somehow
