Question about Launching shell command from Credential Provider

[Guest hkfg9876@yahoo.com]

We need to launch our applicatoin from the

IConnectableCredentialProviderCredential::Connect().

 

I have following questions:

 

1. In the FAQ of Microsoft's "Sample Credential Providers Overview",

Microsoft says, "USER applications may not run on the Winlogon

Desktop". But I launched our application successfully. Can somebody

explain what do they mean what by "user applicatoin"?

 

2. Continuing with the scenarios above, our application will need to

impersonate itself as a specific user and access registry/filesof that

user. Is this feasible? Does the impersonation operation turn our

application into a "User application"?

 

3. When a Credential Provider is destroyed after user logged on, will

the processes it launched be destroyed as well?

 

Thanks!
