(Not a duplicate, because the suggested fix in the linked duplicate DOES NOT WORK, read the whole post!)
I did not delete the Desktop (go to classic Win desktop) tile (icon) from the Start screen, but my system updated, rebooted, and it's gone. The Win+U command, nor the search on the start screen cannot get it back, which is the usual workaround, because it's also completely GONE from inside the start menu, even when searching.
Is there any OTHER way to repair windows or tell Windows to put that tile back?

Update The accepted answer on the linked "duplicate" did not work, but sfc /scannow plus a reboot solved the issue, so while this is perhaps a duplicate, the linked accepted answer is NOT very helpful. I upvoted the answer that helped me, and since this appears to be a bug in windows 8, I hope that other people find the answer that isn't the accepted one, in the linked duplicate.
