Driver Signing

Every now and then, when you try to install the software for one new

gadget or another, you see a warning box that says “Windows can’t verify
the publisher of this driver software.”

It’s not really as scary as it sounds. It’s just telling you that Microsoft has

not tested this driver for Windows 10 compatibility and programming
solidity. (Technically speaking, Microsoft has not put its digital signature on
that driver; it’s an unsigned driver.)

Note

In very rare circumstances, you may also see messages that say “This driver software has been
altered” or “Windows cannot install this driver software.” In those cases, go directly to the
hardware maker’s website to download the official driver software; Windows is trying to warn
you that hackers may have gotten their hands on the driver version you’re trying to install.

In theory, you’re supposed to drop everything and contact the manufacturer
or its website to find out if a Windows 10–certified driver is now available.

In practice, just because a driver isn’t signed doesn’t mean it’s no good; it

may be that the manufacturer simply didn’t pony up the testing fee required
by Microsoft’s Windows Hardware Quality Labs. After all, sometimes
checking with the manufacturer isn’t even possible—for example, it may

have gone to that great dot-com in the sky.

So most people just plow ahead. If the installation winds up making your
system slower or less stable, you can always uninstall the driver, or rewind
