Imagine opening the office fridge and finding a cloudy, unlabeled bottle of milk. You wouldn’t drink it — so why are businesses still running tills, routers and servers on ancient, unsupported software? In this episode Graham, Noel, Lucy and Mauven turn the mic onto the maddening normality of ‘mystery’ machines: the Windows XP till behind the counter, the router older than your youngest employee, the dusty NAS holding the only copy of customer data. With equal parts humour and hard sense, they map food-safety instincts — ‘use by’, ‘best before’, the sniff test — onto the tech that keeps small businesses running.

Through real-world stories (from cafes and dental practices to corner shops and manufacturers) the hosts show how ‘still turns on’ is not the same as ‘still secure’. End-of-life and end-of-support dates are the invisible expiry stickers businesses ignore at their peril: when security updates stop, so does your defence. Graeme lays out pragmatic steps for a no-nonsense tech audit — list devices, note what they do, check support windows, then slap “used by” or “best before” labels on the kit that matters. For anything internet-facing, handling payments, or storing sensitive data, the rule is simple: if it’s out of support, replace it. For unavoidable legacy kit, segment it, lock it down, and plan its retirement.

Practical, urgent and often funny, this episode is a wake-up call for anyone running a small business: don’t let your tech go off the rails just because the lights still come on. Follow the simple 30-minute ‘milk check’ homework, colour-code your inventory by risk, and commit to one concrete fix this month — whether that’s replacing a router, budgeting for a refresh, or scheduling an audit. Share the episode with that friend still running a mystery Windows box. Your customers — and the regulator — will thank you.
