We have a global policy for about 500 computers. For one PC i need to create a new policy which is ONLY affecting this one PC so i decide ill do a local GP. If i did this would the local policy override the global policy or would the global policy override the local policy OR would they merge together?

Thx

Nope - the local GPO is processed first, followed by the site GPO, the domain GPO and then the OU GPO's from the top down to the computer OU. See Group Policy processing and precedence for details.

What you want can be achieved by creating a new GPO and then using GP security filtering to apply the new GPO to the one PC. See How to Implement Group Policy Security Filtering for an explanation.

This pretty much sums up what I was gonna say.
