The best demonstration of the delay is typing Calc in the Win+R Run dialog. There's a difference between instant and "way faster than Word".

On Windows 7, you could hit enter and immediately start typing numbers and it would work. I have never worked on a Windows 10 or 11 machine where it launches instantly.

I get a similar lag when launching Notepad. Not a huge disruption to the day, but annoying to see on a simple utility that used to be better.
