Thank-you for replying. Yes, I could pretend the world still uses MS-DOS and use those old commands I suppose ;) I could also write a PowerShell or script and modify it and paste it in and accomplish the same thing. Or a Python script.
But I would like to use the GUI shell since it's worked the same way for decades, and it would still be faster than any command-line alternative to simply use the (bugged) process I'm facing in File Explorer.
And thanks for that screenshot but that option jumps the focus to the Search Bar, not the Address Bar, and besides that mine is already set as shown.
Thanks for trying! Unfortunately not a solution that works for me.
I did try using the Local Group Policy Editor (gpedit.msc) and set "Turn off display of recent search entries in the File Explorer search box" to "Enabled" and haven't had the issue since, but since it's sporadic I'll have to wait longer to see if it returns. My guess is that this won't fix the issue as it's related to a different function, but maybe I'll get lucky.
