Trying to execute complicated CGI, Photoshop or video editing procedures when a File Explorer window suddenly pulls focus can be disastrous; happens to me several times a day, every day. Maybe Microsoft engineered Windows 11 to be the Annoying Anti-Productivity OS, for reasons unknown.
Totally agree with you Diplo. Just yesterday, I was editing an MS Word document (and has happened before) -- where a string of background explorer windows came up, as I was typing and back-spacing etc. Even though there might be safeguards to prevent particular key combinations (eg. backspace, delete) from activating when those explorer DIRECTORY windows pop-up -- there is always the 'worry' that important directories or files or something could eventually be unknowingly impacted negatively under some unforeseen and unaccounted conditions. Also the fact that it is disruptive when you're working and those windows just pop-up at random. It's unsatisfactory.
