Our readers already know some of the best features in Windows 11 to upgrade for and they made the big step in this direction. However, some of them have asked us what they should do when they encounter the Windows cannot verify digital signature – Code 52 message in Device Manager or DXDiag. The full error is the following one:

Windows cannot verify the digital signature for the drivers required for this device. a recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (code 52)

That being said, having a better understanding of why this error appears and how to better take care of your device and prevent this issue from happening in the future has become a necessity.

Is the digital signature mandatory?

According to Microsoft, the digital signature’s main purpose is to actively protect your system from threats and infections by making sure that the signer is trusted and that the files were not altered in any way after they were published.

Therefore, every single driver and program must be digitally signed before you install and run it on your device. But this isn’t always the case, as not all publishers and vendors are verified and neither are their products.

It is simply impossible for Microsoft to check all the drivers or programs that are published daily and have them digitally signed for your device’s safety.

That is why you can come across driver errors since the OS won’t allow an unsigned legitimate software or driver to work or load as it should.

Error Code 52 main causes

You are about to discover how to troubleshoot this issue, but first, understand that the most common cause is related to incorrectly signed driver files installed on your PC and it mostly occurs after updating or upgrading Windows.

What happens if I disable driver signature enforcement?

As previously said, this Windows feature pretty much guarantees you that your drivers are authentic and unbroken by malicious apps.

A digital signature is an integral part of any operating system, meant to protect your system and prevent you from installing unverified drivers.

When it comes to Windows, the OS actually requires that a driver belongs to a verified developer and that the driver understands that it simply cannot be fraudulent.

If you disable signature enforcement, there will be nothing to prevent you from installing broken, poorly-written, or malicious drivers, which can easily crash your system.

You can also temporarily shut it down, as the ongoing lack of verification can lead to negative computer performance.

So if you don’t wish to disable driver signing permanently, or want to know how to enable it back on, you should check out our full comprehensive guide on driver signature verification.
