Driver Booster
IObit's free Windows driver updater with a 23,000,000-driver database
Driver updater for Windows: five tools compared
A driver updater does one job: it finds drivers that are missing or old and installs newer ones. What separates the five tools on this page is how far each one reaches. Driver Booster, from IObit, scans for over 9.5 million drivers across any PC. Intel Driver & Support Assistant looks only for drivers published by Intel. HP Support Assistant and Lenovo System Update focus on machines from their own makers.

Snappy Driver Installer Origin takes a different route. It is portable and can work offline, which matters on a fresh install with no network driver.
All five are free. None has a Tier A rating here, so every entry is Tier B. Sizes run from 8.3 MB to 169.5 MB, and every tool was updated between July and October 2026. Pick by the hardware you own and by whether you need internet access during the job.

Before running any driver update, check that a recovery option exists. Driver Booster creates a restore point before major updates, according to its developer. For the other four, consider making your own restore point first.
File size is a small but practical difference. Intel's tool and Lenovo's tool are under 9 MB each, while HP Support Assistant is 169.5 MB. On a PC from HP, Lenovo or one with Intel parts, start with the maker's tool. Reach for a general tool only when the brand tool does not cover a device.
