I have Windows 8.1.  some of the issues I've faced : up to 3 minutes to open an email; to click to Reply it responds with "not responding"; takes forever to close; today I received an alert that the calendar isn't working correctly, and  on and on.  I have been reading the Community for months  hoping for some solution. I finally saw what I hoped was an answer: in  Dec tech said to go to the Programs :page, select Windows Live Essentials double click and choose repair.  I did that and it downloaded a repair which seemed instantly to improve the software.  It also directed that I notify the account mgr. to ensure the repair was locked in.  I wasn't sure what that meant so I contacted the Microsoft Windows Acct which asked me to reset my passwords This was a mistake since it caused me no end of trouble getting back into my accounts.  Note: a GEEK Squad rep told me to download Live Mail to an ext. drive; then uninstall Live Mail 2011 and then reinstall it.  Why of why isn't there an update for Live Mail 2011 when sooooo many people have terrible experiences with the current software. This isn't right, so Microsoft should fix it

The Repair did NOT last.  I've tried that many times since and it never locks in..
