A recent test of pre-installed updater software on 10 laptops showed that every single one had security problems. Some laptop manufacturers weren’t using encryption in their updaters. The researchers tested laptops running Windows 8.1 or Windows 10, in both out-of-box and after pending updates were applied. Dell, Asus and Lenovo each had a high-risk vulnerability that could have resulted in arbitrate code execution, while Hewlett Packard and Acer each had two.
