SCEP auto reinstall and other SCEP related Q's

1. Does the SCEP client auto reinstall if the user uninstalls it locally?
2. if it doesnt reinstall whats the best way to ensure a user has scep reinstalled if they uninstall it?
3. If you reinstall a SCEP client manually will SCCM 2012 know to take over the management of it? How does it know to get updates from SCCM?
4. If you set in the EP policy to get updates from config manager does it get the updates directly from the dp without going through the SUP? if you set it to get the updates from WSUS what does that even mean then? since your client only has knowledge of a SUP it doesnt know about any stand alone WSUS servers.

 
 

I'm trying 1 out now. 2 if it doesn't automatically reinstall (I think it will), you can set up a collection that contains PC's that don't have it installed with an advertisement to install it. It may also reinstall with the policy alone. 3. I will pick up the policy that is depoyed to that client and enforce that policy. 4, I'm not sure.  I know you need to have SUP set up and configured for automatic deployment of definations, not sure on the full details of how it works.
 
UPDATE It does reinstall automatically if the policy is deployed saying it needs SCEP2012.
