I received updates yesterday for Office which I applied. Afterward, there was a popup when I opened Windows Live Mail 2011 that said there was an update for Windows Live Essentials. I clicked on it and the update took a couple of seconds. After  the update my display of messages is messed up. At the right of each message listing the listing takes a right turn and displays a mirror image going down the page. The hard right turn starts at an earlier point in each line going down the page. It is the same for messages in the inbox and for sent items.  There are also a lot of unintelligible compressed characters at the bottom of the display. Very, very strange.

Has anyone else experienced this?  I'm using Windows 10, Build 1803. 

Is there any way to undo the update to Windows Live Essentials?
