Thank you for your reply, but I don't see how they could be emails. I haven't associated any email account with Windows Live Mail yet. I only have one email account at the moment, my gmail account, and it is not associated with the WLM software. I have a Windows Live ID, but I don't have Windows Messenger set to load at Startup and I have its service set Manual--it does not start when I open Windows Live Mail. I only add that to exclude the possibility that somehow Windows Messenger was synchronizing with WLM and automatically associating my ID, which is based off of my gmail account, with WLM. If it had, I would not have been happy with WLM having such authority out-of-the-box, so to say, but it does not seem to, which is good.
Let me clarify, I downloaded wlsetup-web.exe, from the Windows Live Essentials page by way of Windows Update as an optional download on the 27th of December in 2009--I had just built this computer and installed the OS. I didn't mean to say that I had just downloaded WLM, I meant to say that I had just run WLM for the first time. All of the folders from "Windows Live Mail" onward in the path:
C:\Users\Michael\AppData\Local\Microsoft\Windows Live Mail\Your Feeds\Feeds for U 29
were created only 14 hours ago, at the moment I first executed the Windows Live Mail program. The "Popular Gov823" folder and the "Usa.gov Upd 8b3" folder are subfolders within the "Feeds for U 29" folder.
I assume they are meant to be examples to demonstrate WLM's ability to aggregate RSS feeds and display them. In Windows Live Mail, under [Your feeds >> Feeds for United States], you will find the associated descriptors for the folders. They are "Popular Government Questions from USA.gov" and "USA.gov Updates: News and Features".
I don't want Microsoft Live Mail, if I should decide to associate my email accounts with its software, to automatically subscribe me to .gov feeds. Next thing you know, my email will be filled with .gov propagandistic spam. I suppose now what I really want to know is, if I delete these folders and then associate an email, will WLM recreate those feeds folders and auto-subscribe me to them? If so, I don't want to use WLM; if not, then I am willing to give it a try.
On the other hand, I will assume--otherwise its time to let paranoia have its day

--other users of WLM have these feeds folders and can tell me if auto-subscription to the .gov feeds do happen, as well as if it has lead to any spamming of their email accounts.
I have never used a desktop email client before, so, if my concerns above are ignorant, please take a moment to enlighten me.
