Same with me. I have been on this for the past 24Hrs just to make sure i do not loose any of my files.
I needed my files/docs intact for an upcoming interview but ALAS!!!
I have been F*^Ked by MICROSOFT ......BIGLY!!!
I followed all the steps carefully , trying different methods to arrive at the least possible damage.
Why Why Why do you have to do this to me NOW!!!
Who do i talk to, who do i sue, Microsoft or Avast!!!.....
I did use their eefing MediaCreationTool1803, downloaded the Win10 Tool to a USB , get it installed via the Task Manager , choose to keep my files and Apps but still got f*&ked!!!
My files are missing/deleted/moved or whatever the h*%l it went.
Why didn't you, Microsoft, warn to backup files or whatever before installing these update.
A painful lesson learnt today.....Always Back Up you files/Apps.
Pity.
