So it wasn't in the ROM then. It's a Windows malicious bloat-ware thing. That Lenovo things is an absolute utter bloody disgrace, and Lenovo should be given a complete spanking and the company should be prosecuted, with jail time for the guilty or clueless. There is absolutely no excuse for not knowing exactly what the bloody hell they are shipping with those machines.
As I said earlier, even though I have Lenovo boxen myself, and have supplied them to my customers, all installations are clean, and my customers always used to get virgin top quality new hard disks or SSDs fitted in the machines. I buy the best quality hard disks that I can get, with long warranties, not whatever Lenovo can get cheapest in volume. And I always used to buy the smallest amount of RAM possible and upgrade it massively myself with top quality Crucial fast sticks, much cheaper that way anyway. If I could save my customer some money then I would, but it was always quality first even if that meant that the price went up. In fact the OEM HD was kept untouched and left in a drawer, so that if the customer's machine needed to go back to Lenovo for repair, the customer's working HD does not go back to the repair centre to be snooped through or tampered with or ruined - the original hd goes back in the box instead. When the machine would eventually get resold one day, the new buyer would get that virgin OEM installation put back into the machine, so that increased the saleability of it as the buyer would then get a machine that worked immediately and the customer would be protected from data leakage. All in the past now as I have been forcibly retired for a long time.
