You are not alone with this peculiar problem, which seems to be an obscure bug in the latest version of WLMail (2009 14.0.8064.0206) which is only very rarely experienced.
I can't explain with certainty why WMail is starting when you start WLMail, but I have a workaround for you that should help if resetting WLMail's defaults does not help.
Firstly, if you want to investigate the reason for this problem, two programs that may be of help are 'Process Explorer' (http://technet.microsoft.com/en-us/s.../bb896653.aspx) and 'Process Monitor' (http://technet.microsoft.com/en-us/s.../bb896645.aspx).
Now, in an another attempt to resolve the problem (if you haven't already tried it), I suggest that you first do a Repair Install of Windows Live Essentials through Control Panel->Programs and Features.
Certainly you can deny a User access to WMail...
1) Close WMail and WLMail
2) Start->Default Programs->Set program access and computer defaults->[x] Custom [check and expand]->Choose a default e-mail program: [section]->[x] Windows Live Mail [check]->[ ] Windows Mail->[ ] Enable access to this program [uncheck]->OK
This will mark WinMail.exe as Hidden and remove its shortcuts.
However, this probably will not prevent WMail from starting up when WLMail is started.
You may then need to rename 'WinMail.exe'* to 'WinMail.exe.bak'. That should see the end of WMail starting up...
Since 'WinMail.exe' has now been marked as Hidden, you will need to so ensure "Show hidden files and folders" is checked under Folder Options in Windows Explorer.
If Windows refuses to allow you to rename 'WinMail.exe', you can use a program called 'Unlocker' (http://********.free.fr/unlocker/) to rename it, or else adjust the permissions of 'WinMail.exe' to give yourself full control over it.
*C:\Program Files\Windows Mail\WinMail.exe
I can't envisage any detrimental side effects from renaming 'WinMail.exe' other than not being able to start WMail, and it no longer appearing in the 'Default Programs' options.
Having WMail access denied as well as 'WinMail.exe' renamed should be enough to satisfy WLMail and Windows itself.
