Device drivers are needed in order for the hardware and software to communicate in an operating system. Some of these drivers are digitally signed. These kinds of drivers are drivers that are signed by their issuing authority in a way that the end-user or any third party won’t be able to modify them. And there are times when you encounter an error that says, “Windows requires a digitally signed driver” when you try to install or update device drivers. Driver Signing is the process of associating a digital signature with a driver package. Digital signatures are used in Windows device installations to verify the identity of the vendor providing the driver packages as well as to verify the integrity of the driver packages. All the drivers you usually install on your PC from Windows Update, Original Equipment Manufacturers, or some other third-party driver download software and so on must be verified digitally by Microsoft through the digital signature. A digital signature is an electronic security mark that verifies the publisher for the driver and all the relevant information related to it. That’s why Windows won’t run a driver if it isn’t certified by Microsoft, be it a 32-bit or 64-bit system – this is called the Driver Signature Enforcement. The only Kernel-mode drivers that Windows 10 will load are the ones that are digitally signed by the Dev Portal. However, the changes only affect the new installations of the operating system with Secure Boot on while the non-upgraded fresh installations would require drivers that are signed by Microsoft. The “Windows requires a digitally signed driver” error indicates that the driver you are trying to update or install hasn’t been signed digitally by the issuing authority, preventing you from installing or updating it. To resolve this issue, you can try to update the drivers directly from the manufacturer’s site. You could also disable driver signing via Group Policy Editor.

Option 1 – Update the device drivers directly from the manufacturer’s site

The reason why you’re getting the “Windows requires a digitally signed driver” error in the first place is that you might have downloaded the drivers from external media. It could also be that the drivers didn’t update for some time now and the issuing authority changed its policies. Thus, you can try to update the drivers straight from the manufacturer’s website and install them. If this option didn’t work, then you’ll have to disable the driver signing or its recognition in Windows 10. Keep in mind that doing so is not advisable if you have to use the concerned driver.

Option 2 – Disable driver signing via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: User configuration > Administrative templates > System > Driver installation
• Next, double click on the “Code signing for device drivers” entry located on the right pane to open its properties where you’ll see the following description:

“This setting determines how the system responds when a user tries to install device driver files that are not digitally signed. It establishes the least secure response permitted on the systems of users in the group. Users can use the System in Control Panel to select a more secure setting, but when this setting is enabled, the system does not implement any setting less secure than the one the setting established. When you enable this setting, use the drop-down box to specify the desired response. “Ignore” directs the system to proceed with the installation even if it includes unsigned files. “Warn” notifies the user that files are not digitally signed and lets the user decide whether to stop or to proceed with the installation and whether to permit unsigned files to be installed. “Warn” is the default. “Block” directs the system to refuse to install unsigned files. As a result, the installation stops, and none of the files in the driver package are installed. To change driver file security without specifying a setting, use System in Control Panel. Right-click My Computer, click Properties, click the Hardware tab, and then click the Driver Signing button.”

• Now select the radio button for “Enabled” and select Ignore from the drop-down menu under “When Windows detects a driver file without a digital signature”.
• Then click on the Apply and OK buttons to save the changes made. This will get rid of the “Windows requires a digitally signed driver” error but take note that this will also make your system less secure.

The Event Viewer in the Windows operating system is used to troubleshoot any computer issues. It is one of the most useful tools that keep logs of both security and system events. It also monitors for both software and hardware problems in the computer. This tool is the only one with amazing features that maintain logs about everything that’s going on in the computer system. It keeps track of all the information to the point where going over them will take a lot of time. Luckily, the Event Viewer tool now allows users to create custom views where you can set the filters and sort the data recorded to limit the information details to only what you’re interested in seeing. For instance, if you want to troubleshoot with one hard drive, you can just create a special custom view to display only the hard drive warnings in the security logs. This will save you hassle and time. Take note that the logs in the Event Viewer are divided into two main categories namely the Window logs and the Application and Services logs. You can just set the filter to the logs by their event id, specific date, and many other events when you have to troubleshoot some problem in your computer. So if you are trying to troubleshoot a problem in your Windows 10 computer and you’re checking the Event Viewer, read on as this post will guide you in creating custom event views in the Event Viewer. To get started, refer to the instructions given below. Step 1: Go to the Start menu and in the search box, type “event viewer” and then click on Event Viewer from the search results to open it. Step 2: After opening Event Viewer, click on Custom Views located in the left pane of the window. Step 3: Next, click on the Administrative events under the Custom View to create special log views. Step 4: Then on the right side of the window, click on Create Custom View to open the Create Custom View window. Step 5: There is a logged drop-down list under Filter. From there, you have the option to choose an appropriate predefined time or use a custom time range for your Custom log views. Step 6: After that, select an appropriate event level for your custom view. You have fine entry-level options to choose from such as critical event level, error, warning, information and verbose.

• Critical – select this if you want to see the events that require your immediate attention in the custom view.
• Error – select this if you want your Event Viewer to display the events that are less critical but hints at the problems.
• Warning – select this event-level if you want to see the event with the potential problem but may not bound to happen.
• Verbose – select this if you want to see detailed information about all the events.

Step 7: After you’ve selected the event level, you now have to select how you want the events to be filtered. They can either be filtered By the log or By the source.

• By the log – you can select two options called Windows log and, Application and Service logs. The Windows logs allow you to filter the logs created during events like setup, security, applications, and system events. While the Application and Service logs filter the log created by the installed applications in your system.
• By the source – select this if you want your Custom View to search for information in event sources. It allows you to view events in detail for various applications and devices.

Note: You have the option to further customize the event logs with more filters like Event IDs, task category, keywords, User, and Computer. Using these additional filters, you can choose to filter the events in the special views by specifying event id numbers in the Event IDs, entering predefined Windows words in the Keyword, specify the user accounts in the User field, as well as choose the system from the server to maintain logs in the Computer field. Step 8: Once you’re done customizing the log filter, click on OK to apply the changes made. Step 9: After that, a Save Filter should be displayed in the Custom View window. Just enter the Custom View name and select the Event Viewer folder where you want to save the Custom view. The folder name should be Custom View by default. And if you want, you can also create your own folder if you want your custom views to be visible to all the system users. Step 10: Next, check all the Users box located in the lower corner of the window and then click the OK button after you’re done. You should now see the customized filter you just created on the left side of the window. Just click on it to check your filtered events in the center of the Event Viewer window. And for you to save the custom view logs, simply right-click on the Custom views you created and then click on Save All Events in the Custom View As from the drop-down menu. Then put a name on the file and select the appropriate location where you want to save the logs and click on the Save button. Note that the log file is saved with the “.EVTX” file extension and when you double click on it, it will open the file in the Event Viewer.

As you know, DLL files in the Windows environment contain all the code needed by programs in order to properly function. And like with most other software, the functions in the DLL file have to be compatible with Windows especially if they are using any built-in service. So if you encounter an error that says, “DLL is either not designed to run on Windows or it contains an error”, when you try to launch a program, then this could be due to a compatibility issue. To fix this error, read on as this post will walk you through doing that. Based on the reports of users who encountered this error, the error pointed to a DLL file that was either designed to run on a different version of Windows. It is also possible that the DLL file itself is the problem. Here’s the complete error message:

“Bad Image – DLL file is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.”

According to security experts, the DLL files that are known to trigger this kind of error message are msvcr100.dll, msvcr110.dll, msvcp140.dll, lmirfsclientnp.dll, and so on. To fix this problem, you can try to update or reinstall the program that’s throwing the error to its latest version. You could also ask the vendor for the latest version of the DLL as well as run a System File Checker scan.

Option 1 – Try to update or reinstall the program to its latest version

The first thing you can do to fix the problem is to update or reinstall the program that’s throwing the error. It is possible that the version of DLL might be using a system call that is deprecated. So if you had updated your Windows 10 computer recently, you might want to check for an update of the software or you could also try to reinstall its latest version.

Option 2 – Try asking the vendor for the latest version of the DLL

The next thing you can do to fix the error is to ask for the latest version of DLL from the vendor. There are times when the software uses an open-source version of DLL so it is better if you ask the vendor if there is a DLL file that has to be updated. If there is, then you need to make sure to register the DLL once you have it.

Option 3 – Try to re-register the problematic DLL file

You can also try to re-register the DLL to resolve the problem. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
