No file downloaded? Device Manager is a Windows utility that allows you to update and reinstall drivers for individual devices (e.g. your video card, sound card or network card) for free. Most people use it the first time they try to update a driver. Unfortunately, it’s a very tedious way of identifying which devices have outdated drivers, because it doesn’t flag them. To find out if a driver is out of date, you have to actually try to update it. If Windows thinks the driver is out of date, it will update it for you; if not, it will tell you you already have the latest driver. Obviously doing that for every single device takes a long time. And to make matters worse, Device Manager often won’t give you the latest driver anyway . That’s because it categorizes driver updates as either ‘critical’, ‘automatic’ or ‘optional’, and it doesn’t usually concern itself with the ‘optional’ ones. So long as you have the updates it calls ‘critical’ and ‘automatic’, it’s happy. It won’t, for example, install a new ‘optional’ update, if it already has an old ‘critical’ update installed.

If Windows thinks the driver is out of date, it will update it for you; if not, it will tell you you already have the latest driver. IMPORTANT: As discussed later on this page , Windows Device Manager doesn’t always detect outdated drivers. Nor does it always give you the latest available version if you update a driver.

If you want to be sure you have the latest available version of a driver, you need to source the driver directly from the manufacturer or use a tool like ours, called Driver Easy , to do it automatically. What Windows Device Manager DOESN’T do Windows Device Manager doesn’t always detect outdated drivers. Particularly in Windows 10/11. That’s because it categorizes driver updates as either ‘critical’, ‘automatic’ or ‘optional’, and it doesn’t usually concern itself with the ‘optional’ ones. So long as you have the necessary ‘critical’ and ‘automatic’ updates, it’s happy. It won’t, for example, install a new ‘optional’ update, if it already has an old ‘critical’ update installed. Here’s a quote from Microsoft itself : Windows offers the best matching driver, which is not necessarily the most recent. The driver selection process considers hardware ID, date/version, and critical/automatic/optional category. Windows prioritizes critical or automatic drivers highest. If a matching driver is not found, WU looks next for optional drivers. As a result, an older critical driver of otherwise equal value takes precedence over a newer optional driver. But all driver updates are important, even when Windows calls them ‘optional’. If they weren’t, the hardware manufacturers wouldn’t go to all the trouble of coding and releasing them. Sometimes these ‘optional’ updates include just a new, nice-to-have feature, and you can arguably do without that. But sometimes it’s an important bug fix – perhaps the old driver is causing your device to stop working or your computer to crash. Windows often categorizes these updates as ‘Critical’, but definitely not always. Other times, it’s not Device Manager’s fault at all. It’s just that the device manufacturer has failed to include the driver you need in the latest Windows Update. Watch this video for more information on how this happens: Issues you’ll encounter when Windows Device Manager won’t update a device driver Whether it’s a Microsoft issue or a device manufacturer issue, if Windows doesn’t detect that your device drivers are out of date then: If you try to update a device’s driver as described above, Windows Device Manager will tell you the driver is already up to date, even though it’s not; and If you try to update a device’s driver as described above, Windows Device Manager will tell you the driver is already up to date, even though it’s not; and You could be missing out on important device functionality, and you may be suffering through completely unnecessary computer issues (e.g. computer crashes or very slow performance). You could be missing out on important device functionality, and you may be suffering through completely unnecessary computer issues (e.g. computer crashes or very slow performance). What to do when Windows Device Manager won’t update a device driver If you’re unable to update a device driver in Windows Device Manager, Microsoft says : If Windows doesn’t find a new driver, you can try looking for one on the device manufacturer’s website and follow their instructions. But to do this, you’ll need to know the brand and model of the device, as well as your exact operating system and whether it’s 32 or 64 bit. Then you have to find the manufacturer’s driver download page, find the correct driver, and check that it’s newer than the one you already have installed. Then, of course, you have to download and install the driver – quite often a complex process, in itself. Obviously this takes a lot of time, but it also requires quite a bit of technical expertise.
