Hi all:

I've got a question regarding retrieving a value from the Registry

within Vista that I hope someone here can help me answer.

Here's the situation. I've got an existing application that has been

working just fine under Windows XP Pro. At application startup, it queries

the Registry to retrieve the following key value:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Logon

User Name

This value is then used to check in a Security table for a match on the

name. (Yes, I know this is an odd logon situation; it's what the client

wanted.)

The thing is, now they're looking to move to Vista. And, for some

reason, this key value does not exist in Vista.

Can someone point me to a reference of registry keys for Vista? Or can

someone recommend to me a key value I could use that would return the Logon

User Name? Unfortunately, I don't have direct access to Vista, so I can't

just open up the Registry and browse around to find the appropriate key.

Any help you can send my way will be greatly appreciated.

Jon
