A Windows 10 update changed my user account name to username.000 and deleted my original name. My Photoshop elements has all my photos connected to my old user name which is now extinct. Is there a method to edit the location path in elements to point to my new windows username without having to manually have to reconnect each group of photos
Assuming that you can still access your catalog folder, you simply need to browse to it under the new user name path. Perhaps the easiest way to do it is to search for a file called catalog.pseXXdb where XX refers to your Elements version number. Elements 2020 is version 18 so its database file is catalog.pse18db. When you have located the file, double-click on it and the catalog should open in whatever version of Elements you have.
Alternatively, use the Organizer's File>Manage Catalogs dialog to browse to the catalog folder.
