Windows requires a digitally signed driver

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.

NoteHomepage removal guide

NoteHomepage (by MyWay) is a browser extension that may be bundled with other free software that you download off of the Internet, or delivered via other advertising means. When installed NoteHomepage will set the homepage and search engine for your web browser to http://search.myway.com. While installing this extension will gather information from your browsing sessions, including website visits, clicked links, and sometimes even private information, that it later sends back to display unwanted ads into your browser. Several anti-virus scanners have marked this extension as a Browser Hijacker and are therefore not recommended to keep on your computer. It is considered potentially unwanted, and many users wish to remove it, so it is flagged for optional deletion.

About Browser Hijackers

Browser hijacking is a form of unwanted software program, usually a web browser add-on or extension, which then causes modifications in the web browser’s settings. Browser hijacker malware is developed for many different reasons. Generally, browser hijacking is utilized for earning advertising revenue from forced advert mouse clicks and site visits. Even though it might seem harmless, these tools are designed by malicious individuals who always look to take full advantage of you, so that they can earn money from your naivety and distraction. Some browser hijackers are programmed to make certain modifications beyond the browsers, like altering entries on the system registry and letting other malware further damage your machine.

Find out how to identify a browser hijack

Below are some signs and symptoms that suggest your browser has been hijacked: the home page of your browser is changed unexpectedly; your browser is constantly being redirected to adult websites; the default search engine is changed; you are getting browser toolbars you have never noticed before; never-ending pop-up advertisements show up and/or your web browser popup blocker is disabled; your web browser gets sluggish, buggy, crashes regularly; Inability to navigate to certain websites, particularly anti-malware and also other security software websites.

So how exactly does a browser hijacker infect a computer?

Browser hijackers might use drive-by downloads or file-sharing networks or an e-mail attachment in order to reach a targeted PC. They could also come from add-on programs, also called browser helper objects (BHO), web browser plug-ins, or toolbars. Browser hijackers sneak into your computer in addition to free software application downloads also that you unknowingly install alongside the original. A good example of some infamous browser hijackers includes Babylon, Anyprotect, Conduit, SweetPage, DefaultTab, Delta Search, and RocketTab, however, the names are regularly changing. Browser hijackers will affect the user’s web surfing experience severely, track the websites frequented by users and steal personal information, cause difficulty in connecting to the web, and eventually create stability problems, causing software programs and systems to crash.

Learn how to remove browser hijackers

Some hijackers can be removed by just uninstalling the corresponding freeware or add-ons through the Add or Remove Programs in the Windows control panel. But, many browser hijackers are difficult to get rid of manually. No matter how much you try to get rid of it, it might keep returning again and again. Additionally, manual removals demand in-depth system knowledge and thus can be a very difficult job for novices. Industry experts always suggest users remove any malicious software including browser hijacker with an automatic malware removal tool, which is easier, safer, and quicker than the manual removal method. Employ a PC optimizer along with your anti-malware software to solve various registry issues, remove computer vulnerabilities, and boost your computer performance.

Download the software in Safe Mode with Networking

Fix ndis.sys failed BSOD error on Windows 10
NDIS or Network Driver Interface Specification is a programming interface for the network interface cards that aids in the proper functioning of a system driver in a computer network. The NDIS helps the computer system in order to communicate with other connected devices and hardware components on a computer network. In relation, the ndis.sys file is a critical system file developed by Microsoft for the Windows operating system. As you know, sys files or system files are important parts of the Windows operating system as well as a repository of system driver settings used by Windows to communicate with the connected hardware and devices. The ndis.sys files are stored mostly in a driver folder at C:/Windows/System32/drivers and as mentioned, these files are essential for the system to function properly. Although the presence of ndis.sys system file is not yet known to affect the normal functioning of the Windows OS, some of the Windows 10 users reported that they encountered ndis.sys blue screen errors on their PCs. Blue Screen of Death errors or Stop errors usually occurs when you open a program or a function. Moreover, it could also occur when the driver gets loaded during the system startup or during system shutdown. It isn’t yet clear what really causes the ndis.sys blue screen error. However, like other Stop errors, it may occur due to corrupted files, misconfigured device drivers, bad drivers, corrupted Windows Registry, missing or damaged system files, and malicious programs. Aside from the aforementioned reasons, the ndis.sys blue screen error might also occur if your hard disk is damaged and if the RAM is corrupted. In such cases, a lot of users usually disable the ndis.sys file. However, it won’t really resolve the issue since the file is required for the normal functioning of the operating system and even when you disable the file, it’s pretty useless as the file will start all over again. In addition, you might want to disable security programs or firewalls and antivirus programs in the meantime to check if these programs are the ones that are causing the error. And if you’ve determined that none of the security programs or firewalls and antivirus programs are to blame, refer to the options below that might help you resolve the DRIVER_IRQL_NOT_LESS_OR_EQUAL or ndis.sys Blue Screen of Death error.

Option 1 – Try to update or reinstall the PC device driver

The Ndis.sys Blue screen error can occur when the device driver in your computer is outdated or corrupted. Thus, you either have to update or reinstall it to fix the issue.
  • Tap the Win + R keys to launch Run.
  • Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
  • Restart your PC.

Option 2 – Rollback your Network drivers

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:
  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
  • Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
  • Then select each one of them and double-click to open a new mini window.
  • After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
  • Now restart your computer to successfully apply the changes made.

Option 3 – Try running the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the ndis.sys Blue Screen of Death error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow and hit Enter.
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Try running the CHKDSK utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.
  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the following command and hit Enter:
chkdsk /f /r
  • Wait for the process to be completed and then restart your computer.

Option 5 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:
  • Open the Command Prompt as admin.
  • Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
  • The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
  • Restart your PC.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the ndis.sys Blue Screen of Death error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
  • After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

DNS_PROBE_FINISHED_BAD_CONFIG error in Chrome
If you always use Google Chrome when browsing the internet, then you might have come across an error saying, “This webpage is not available, DNS PROBE FINISHED BAD CONFIG”. If you do, then this problem certainly has something to do with the DNS since any error code which has “DNS” in it points out a network issue in the computer. Getting the DNS_PROBE_FINISHED_BAD_CONFIG error indicates that your computer is not able to connect the website because the Domain Name Server or DNS wasn’t able to resolve the website name into IP address or it is not available at all. So in this guide, we’ll help you sort out this issue in Chrome on your Windows 10 PC.

Option 1 – Check the Network Cables and restart your router then reconnect

The most obvious thing you can do first is to try checking if the network cables connected to your computer or router are properly connected or not. If it turns out that some network cables are not connected properly, then it’s probably why you’re getting the DNS_PROBE_FINISHED_BAD_CONFIG error in Chrome. And if your computer is connected via Wi-Fi, you need to make sure to restart your router once. In addition, you can also forget the Wi-Fi your computer is currently connected to and then try reconnecting again to see if it would work.

Option 2 – Flush the DNS and reset TCP/IP

Flushing the DNS and reset TCP/IP could also help in fixing the DNS_PROBE_FINISHED_BAD_CONFIG error in Chrome. To do so, refer to these steps:
  • Click the Start button and type in “command prompt” in the field.
  • From the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
  • After opening Command Prompt, you have to type each one of the commands listed below. Just make sure that after you type each command, you hit Enter
    • ipconfig /release
    • ipconfig /all
    • ipconfig /flushdns
    • ipconfig /renew
    • netsh int ip set dns
    • netsh winsock reset
After you key in the commands listed above, the DNS cache will be flushed and the Winsock, as well as the TCP/IP, will reset.

Option 3 – Try to remove the Proxy

You can also try to remove the Proxy as it might also help you in fixing the DNS_PROBE_FINISHED_BAD_CONFIG error. Here’s how you can do it:
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
  • After that, go to the Connections tab and select the LAN settings.
  • From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
  • Now click the OK and the Apply buttons.
  • Restart your PC.
Note: If you are using a third-party proxy service, you have to disable it.

Option 4 – Change the DNS

Try to use the Google Public DNS If the first option didn’t work, you can try to use the Public DNS by Google and see if it can help fix the DNS error. You have to modify the DNS settings in your system explicitly and use the DNS IP addresses.
  • The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
  • Next, click on the “Change Adapter Settings” option.
  • After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
  • Right-click on your network connection and click on Properties.
  • Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
  • After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
  • Type in “8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Clear Chrome’s browsing data

If your browsing data in Chrome hasn’t been cleared for some time now then that might be the reason why you’re suddenly getting the DNS_PROBE_FINISHED_BAD_CONFIG error when you browse the web. To fix this error, you need to clear your web browsing data. Refer to the following steps to do so.
  • Tap the Ctrl + Shift + Delete buttons to go to the Clear browsing data section in Chrome.
  • Next, set the time range to “All time” and tick all the boxes and then click on the Clear data button.
  • After that, restart the Chrome browser and try to open the website you were trying to open earlier.

Option 6 – Try running the Chrome Cleanup tool

In case you don’t know, there is actually a built-in malware scanner and cleanup tool in Chrome that helps you get rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and other things that could affect the performance of the browser.

      • kill -9 (provide process ids obtained by previous commands individually)
  4. To start the license server automatically after the system reboot
    • Open /etc/rc.d/rc.local script as root and enter license server start up command in it.
touch /var/lock/subsys/local /opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/adsk_license.lic -l /opt/flexnetserver/server_log.logNote: To ensure that the script will be executed during boot, run following command as root. chmod +x /etc/rc.d/rc.local
  1. Make sure that all necessary ports are open:
  • lmgrd.exe needs ports 27000 to 27009.
  • adskflex.exe needs port 2080.
Note: Errors may occur if the network license file is corrupt or in the case of a combined network license it has incorrectly combined licenses. To learn more about combining licenses, see Combining License Files for Multiple Autodesk Products. Use the License File Parser to verify that the license contains the appropriate products and FLEXnet feature codes and does not display an error

Verify that TCP ports (2080, 27000-27009) used by Autodesk Network License Manager are not blocked by Firewall.

The FLEXlm® based version uses the following incoming ports:
  • TCP ports 2080 (for the adskflex vendor daemon)
  • TCP ports 27000 to 27009 (for the lmgrd master daemon, which uses the first open port in the range)
Note: If these port addresses are restricted by a router or firewall software, users on the remote side of the router will not have access to licenses controlled by the Network License Manager.

Verify that the client computer is configured with the correct license server name or IP.

Windows:

Clear license server information from the system registry.

  1. Type regedit in the Windows Search box and hit Enter key.
  2. Select the following registry key
  • [HKEY_CURRENT_USER\SOFTWARE\FLEXlm License Manager]
  1. As the key is selected, in right panel ADSKFLEX_LICENSE_FILE will be visible.
  2. Right click on the key and delete it.

Specify the license server in ADSKFLEX_LICENSE_FILE system variable 

  1. Go to Start > Control Panel > System and Security > System.
  2. Select Advanced system settings.
  3. On the System Properties dialog, click Environment Variables.
  4. Under System Variables, click New.
  5. Enter ADSKFLEX_LICENSE_FILE for the variable name and 2080@SERVER_NAME _OR _IP for the variable value.
Note: the license server information most often is recorded in LICPATH.lic file and can be verified there too.  ADSKFLEX_LICENSE_FILE system variable supersedes LICPATH.lic.  Thus, setting the system variable is preferable when this error is seen.

If the license server is on a VPN or a remote network set the FLEXLM_TIMEOUT environment variable:

  1. Go to Start > Control Panel > System and Security > System.
  2. Select Advanced system settings.
  3. On the System Properties dialog, click Environment Variables.
  4. Under System Variables, click New.
  5. Enter FLEXLM_TIMEOUT for the variable name and 5000000 for the variable value.
  6. Click OK to save the setting.
Note: if needed the variable value can be increased to 10000000.

Mac/Linux:

Specify the Autodesk Network License server information in $HOME/.flexlmrc file.

Use a text editor to create a flexlmrc.txt file and save it in Plain text format (In TextEdit on Mac: Format - Make Plain Text) on desktop. The file content should look like this, except with the name or IP address of the license server.
  • ADSKFLEX_LICENSE_FILE=@SERVER_NAME _OR _IP
If the license server is on the same machine as the Autodesk software, use localhost as the license server name.  Thus, the content of flexlmrc file could look like this:
  • ADSKFLEX_LICENSE_FILE=@localhost
Note: On firewall restricted network or when accessing the license server via VPN, need to include TCP port/s (usually 27000 or 2080) into Autodesk License Server service as follows: ADSKFLEX_LICENSE_FILE=2080@SERVER_NAME _OR _IP

Once flexlmrc file is created move it to user's $HOME folder as follows:

  1. Open a Terminal window
  2. Type open ~ (Mac) or nautilus ~ (Linux) to open $HOME folder
  3. Drag and drop flexlmrc.txt file from Desktop to the home folder.
  4. To make the file a configuration file, rename it to .flexlmrc (please note . [DOT] in front of the file name) by running the following command:
  • mv flexlmrc.txt .flexlmrc (Mac)
  • mv flexlmrc .flexlmrc (Linux)

Verify that the license server information registered with the product is correct (versions 2020 and later only)

In versions 2020 and later, the license server information is registered with the AdskLicensing service running locally on the workstation. When changing to a new license server, the old server information may still be registered with AdskLicensing and result in the error above, if this is not appropriately updated. See the below steps to solve this:
  1. Click the Start menu and type cmd.
  2. Right-click on the Command prompt and choose "Run As Administrator."
  3. In the Command prompt, run the following command, followed by ENTER:

"C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\helper\AdskLicensingInstHelper.exe" change -pk PRODKEY -pv VER.0.0.F -lm "" -ls "" -lt""

Note:

  • Replace PRODKEY with the product key correspondent to your product(s). See Look Up Product Keys for the full list.
  • Replace VER with the version you are using. E.g. 2020 for AutoCAD 2020.
  • Repeat this step for each software you need to reset.
  1. Open Registry Editor (Start > type regedit > ENTER).
  2. Navigate to HKEY_CURRENT_USER\Software\FLEXlm License Manager.
  3. On the right-side, verify of the ADSKFLEX_LICENSE_FILE key exists. If yes, remove it (right-click > Delete).
  4. Run the software again.
  5. Select Multi-user in the Let's Get Started screen.
  6. Follow the steps to connect to your license server.
