Steven, it's not a Cumulative in the normal sense. It's a test update. Does nothing to any code, just testing the servicing. If you skip it, you'll get it again. Might as well just do it, it's very quick. Has a short install of the Servicing Stack, then the "practice" install (of nothing, really), then a reboot. Takes all of about 4-5 minutes.
