The company has published a support page explaining that a new bug in Windows 10 can prevent users from manually installing drivers on their PCs. Users will receive the error message: "A driver can't load on this device" and it can break installations even after they appear to complete successfully. Microsoft states "If you choose to continue using your device without addressing the driver problem, you might discover that the functionality the driver supports does not work any longer, which could have consequences ranging from negligible to severe." Third party drivers can be essential, particularly for legacy devices, so Microsoft has offered a workaround which (perhaps surprisingly) involves turning off a Windows 10 security setting that guards memory integrity to allow the driver installation to complete
It is an acknowledgment that there is a flaw somewhere in the published driver architecture, rather than an easy-to-fix bug in Windows. Manufacturers have created many proprietary drivers in the last several years which were validated and have been working for years, and now with a Windows update, those drivers may stop working unexpectedly.
- See if an updated and compatible driver is available through Windows Update or from the driver manufacturer.
- Turn the Memory integrity setting Off if it isn’t already. You'll need to restart your computer for the changes to take effect.
