About half-a-month, since Windows Live Essentials 2011 hit the Release to Web (RTW) milestone, Microsoft is gearing up to deliver automatic upgrades for all users with Windows releases that support the latest WLE.
Essentials 2011 will be served automatically to customers running Windows 7 and Windows Vista SP2 in the next few weeks, through Microsoft Update. According to Microsoft, some users have already started seeing WLE 2011 being delivered through Windows Update as of Oct'19th, 2010.
However, it's important to note that only Win7 and Vista SP2 customers who've enabled Windows Update service will be served the upgrade automatically.
"If you've configured your computer to automatically download Recommended Updates then it'll download automatically. After download is complete, WU will notify you of available updates, and you can start the upgrade. It'll not install automatically."
