So, I just found out my work laptop is still rocking Windows 10 21H2, which I assume is the digital equivalent of showing up to a streaming party with a VHS tape. How worried should I be about security updates, performance, or my general standing as a functioning member of modern society? Should I start making backups now, or just accept my fate and wait for Clippy to come back like some digital poltergeist? Any horror stories, survival tips, or links to the nearest digital time machine appreciated.
