The browser is one to commonly put personal identifiers in the title bar. Pretty much every site you visit puts PII in the title, which the browser dutifully includes in it's title. GSuite leaks my email address: "Inbox - my.email@example.corp - Example Corp Mail - Mozilla Firefox" Desktop apps are pretty much no different. Outlook leaks my email address, and subject lines of emails or meeting information: "Inbox - my.email@example.corp - Outlook" "EMBARGOED Friday 7th ::: Corp Revenue for 2019, +25% over expectations! - Mesage (HTML)" "Meeting: Pre-Announcement, Dial-In +1 555 1234 ext 1234" Visual Studio leaks filenames, repository information: "page.html - corp-project-repo - Visual Studio Code" Pretty sure most office suite and Adobe apps will do something similar.
