not nearly as impressive, but i got past the software lock at a gaming internet café as a 16 year old by hitting (i think it was) Win + I to open a windows accessibility screen, which had a link to a Microsoft page. when clicked it opened a web browser and bam.
There was a Windows built-in input method (智能ABC) that will show a small floating bar wherever there's an input. So you can trigger that bar, right click and select "Help" to open the default CHM viewer, then you can open any URLs from there.
Or alternatively the input method has a secret sequence that will crash any apps: v UP DEL ENTER and boom.
