I have had issue with this message box for a number of years. Years ago it read, "Spelling check is complete" and to refer to the feature as spelling check felt wrong -- it nauseates me. I normally refer to it as, in US English, spell check or spell checker.
I could easily ignore my visceral response to "Spelling check" but it pales in comparison to my disdain for the informal Monster energy drink fueled, sleep deprived, LINUX programmer addition of "You're good to go!" Really?
I suppose Windows tried to be cool by adding that. Rather than make Microsoft look cool, however, it makes it look disrespectful and overrun by a bunch of 20-somethings that exist solely to monitor Facebook or their Twitter feed.
Ranting aside,
I would like to see a formality setting for messages from the operating system. Much like internationalization (I18n) addresses the language between the end user and the operating system, formalization (F11n), would allow for interactions to have personality
ranging from dude-speak "Duuuuude, you're good to go," to Orwellian new-speak, "There is a 10% increase in correct spelling this week. That's double-plus good," to the familiar and accurate "Spell check complete."
Alternately, if there's a way to edit the binary containing this and any other message in Windows 10, I would gladly support the hack (or start a business to create it).
Lastly, I've installed UBUNTU on what used to be my Windows 7 machine. I like it. I like it so much so that I'm "good to go" and install LINUX on this computer if need be. Just sayin'.
