If you haven’t already found it then give the Windows 10 Task View a look. Super quick to switch between all your open tasks, including people talking in a meeting, and then scroll down to see all the recent files. It remembers what you’ve edited for the last month across all applications!

There is also the facility to have different virtual desktops so you can have a different desktop for different work tasks or maybe create a work and personal desktop. More information on the Microsoft page for using multiple desktops
