July 2020 update screwed up my computer

After the July 2020 update, my printer was no longer recognized and my Windows Mail Live would not display the body of the message.  I tried the defragment/compact Windows Live Mail date to fix the problem.  It showed that it was successful but now I can't even open my mail.  Why does Microsoft push these updates and then not give us a way to recover from the errors the updates cause?  I tried uninstalling the updates and it fixed my printer but I still can't get into Windows Live Mail.  Help
