I recently performed a clean install of Windows 7 Ultimate off a Dell OEM DVD after installing two new SSD's on July 29, 2016.  Windows 7 auto activated, I did not have to enter my key code. Following installation Dell Diagnostics which did not reveal any hardware problems.   I downloaded Windows Live Essentials for the Live Mail program. I installed this program and it was properly running and downloading my emails. Approximately one day after installing Windows Live Mail the program was removed from my computer. I did not delete it. Also deleted were the other programs in Windows Live Essentials, which I downloaded with the Live Mail program.

I had also pinned it to my start menu and the corresponding icon was also removed.   Also noted that I have been having difficulty with Windows 7 Updates, which have not been functioning following reinstallation.   Does anyone have any ideas as to why the Live Mail program was removed?  Thanks for your help.
