After upgrading to Windows 10 and successful configuration of Windows Live Mail (WiLM), everything was going on smoothly till a week ago when the Windows Live Mail stopped functioning and threw up the error code 0x80090326. Tried re-installation of WiLM but no success. Was heavily dependent on WiLM and had two very important accounts configured. Have I lost all the earlier mails? How can I get the WiLM to get going again?   ....SOS...

Incidentally, my Windows Upgrade Option has also started playing up and  options are NOT displayed when in the Settings Panel under Windows Update...

Should I be regretting for upgrading to Win 10??
