Newbie, running XP SP2, IE7, Microsoft Outlook2000.

I need some clarification on instructions from a Microsoft Help and Support
article, titled "Save password setting not retained in Outlook"
Here's a portion of the instructions I don't quite understand, listed in
steps 10. and 11.


How to Remove The User Account Information in the registry
Step 10. Reads:
Double-click the Protected Storage System Provider key to expand the key,
click the user subkey folder that is directly underneath the Protected
Storage System Provider key, click Delete on the Edit menu, and then click
Yes in the warning message dialog box.

The user subkey folder looks similar to the following example:

S-1-5-21-124525095-708259637-1543119021-16701

Note For every identity that you have, there will be a subkey under the
Protected Storage System Provider key. To resolve this problem in all your
identities, you must delete all the user subkeys folders under the Protected
Storage System Provider key.

--------------------------------------------------------

My Dilemma: After I double-click on the Protected Storage System Provider:
Two folders are revealed..

The first folder - directly underneath the Protected Storage System Provider
Folder reads: S-1-5-18
The second Folder- is similar to their example of:
S-1-5-21-124525095-708259637-1543119021-16701

Not knowing what a Key is makes this confusing. It would be self explanatory
if the long sequence of numbers fell directly under the Protected Storage
System Provider folder. Is S-1-5-18 not a Key?

Thank you
