After trying Windows 10 for a few weeks and not willing to accept a few issues with 10, I went back to Windows7.  Initially I had some of my desktop shortcut icons with a padlock on them (fixed that).  Kept getting message that Live Mail was reecovering database every time I opened the program.  Tried a Windows shadow recovery from prior to downloaded 10-didn't fix problems.  Then restored all files from a backup I did prior to 10--many, many files (I'm guessing several hundred) were not restored (I made a notepad copy).  Now I can't delete some emails from my inbox, some can be deleted.  Trying the repair option on Live Essentials several times has not fixed Mail 2012.   What can I do to get Windows Live Mail 2012 to work as it did prior to trying Windows10?  Microsoft forums suggest I'm not alone and no fixes

were found there.  Thanks to someone that has the answer.
