1. Open the following directory:

   %USERPROFILE%\AppData\Local\Google\Chrome\User Data

2. Open the file called Local State and use some regex to add new lines at each { and }
3. Look for the following JSON segment:

   "profile":{
   ...
   "Default":{
   ...
   is_using_default_avatar":true,  <--- SET TO false   
   ...
   "use_gaia_picture":false,  <--- SET TO true
   ...}
   ,"Profile 1":{
   ...
   is_using_default_avatar":true,  <--- SET TO false
