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.

If you are trying to install or reinstall a program on your Windows 10 computer but encountered an error instead that says, “Fatal error, Installation fails, Installation ended prematurely because of an error”, then you’ve come to the right place as this post will guide you how you can fix it. This kind of error is most likely caused by some files that may have been left behind by the previous installation of the program. Each time a program is uninstalled, it leaves behind its files and if the uninstallation process wasn’t completed properly, then it would result in errors like the

“Fatal error, Installation fails, Installation ended prematurely because of an error”.

Moreover, this kind of error is a generic one that can also occur with any software reinstallation or installation. And to fix this error, there are several suggestions you must check out. You can try to install or reinstall the program in a Clean Boot State or restart the Windows Installer Service. You could also try to re-register the Windows Installer Service or re-register the VBScript.dll file.

Option 1 – Install or reinstall the program in a Clean Boot State

It is possible that there are some third-party applications in your computer that are preventing the program from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the program again.

Option 2 – Try to restart the Windows Installer Service

The next thing you can do to fix the problem is to restart the Windows Installer Service. To do this, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and then hit Enter to open the Windows Services Manager.
• Next, look for the Windows Installer service among the list of services shown.
• Once you found it, right-click on it and open its Properties.
• From there, click on the Stop button and then click on the Start button.
• But if it isn’t running, then just click on the Start button.

Option 3 – Try to unregister and re-register the Windows Installer Module

• Tap the Win + R keys to open the Run dialog box.
• Then type the “msiexec /unregister” command and hit Enter to unregister the Windows Installer Module.
• Next, type the “msiexec /regserver” command and hit Enter to re-register the Windows Installer Module.
• Now restart your computer and see if unregistering and re-registering the Windows Installer Module fixed the problem or not.

Option 4 – Try to re-register the vbscript.dll file

You may have to re-register the vbscript.dll file using the regsvr32.exe before you can successfully install the program and fix the error. The Regsvr32 tool is a command-line utility that can be used to register and un-register the OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type regsvr32.exe vbscript.dll 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.
• You should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

If you have been using Windows for quite some time now then you’re probably aware of the BIOS or UEFI password. This password lock is the one that ensures you enter the set password even before your Windows PC boots up. However, there’s just one downside with the BIOS or UEFI password – there is no recovery option, unlike your Microsoft account. Worry not though for this post will guide you on how you can set or recover a BIOS or UEFI password on your Windows computer. The BIOS or UEFI passwords are stored at the hardware level which means that unless the OEM wants or has configured a way to recover the password, it is pretty much impossible to reset it. There are times when they are so strict that the only way to get through it by contacting customer care. Note that any Windows computer with this lock can’t be unlocked by trying to reinstall Windows. In this post, you’re going to have to remove the CMOS battery temporarily, clear unknown BIOS/UEFI passwords using the bios-PW website as well as call customer care. For more details, refer to the options provided below.

Option 1 – Remove the CMOS battery temporarily

In case you didn’t know, every motherboard comes with a CMOS battery which helps the computer system to keep the clock ticking and in making sure that the BIOS settings are not lost when the computer is powered down. Every time a computer is turned on, the CMOS battery ensures that the information is available for the computer to boot up. So when you remove the CMOS battery temporarily, say about 30 seconds or a minute, the settings will be lost. There are some motherboards that are built-in ways that when you remove the battery for long, it will reset everything including the password for the BIOS or UEFI.

Option 2 – Clear the unknown BIOS or UEFI passwords using a bios-PW website

If the first option didn’t work, you can try using this BIOS Password website at http://bios-pw.org/ to clear the password.

• When prompted by the BIOS, enter the wrong password a couple of times as doing so will lock you out of the system.
• After that, you will see a new number or code on the screen which will include a message about System Disabled [XXXXX] Service TAG [YYYYY].
• Next, open the BIOS Password website and enter the XXXXX code in it and make sure to tap the Shift + Enter keys or just enter.
• Now it will open multiple unlock keys which you can use to clear out the BIOS or UEFI lock on your Windows PC.

Option 3 – Call the customer care

If the second option still didn’t work, you have to call customer care and follow their suggestions for they will walk you through fixing the problem using the service tag or might suggest that you visit a service center to make things easier for you. Note: You also have the option to set a BIOS or UEFI password. Although it isn’t recommended, you still can do it if you really want to. Remember that the BIOS or UEFI interface varies from OEM to OEM so you must find something related to either PASSWORD or SECURITY. You will have the following similar options:

• Supervisor password – it’s the same as the master password that can change important system settings.
• User password – with this password, any user can change minor settings.
• Master password – you can use this password for a hard drive or as a general password.

There are several OEMs that offer micro-control where you have to enter the BIOS password. For instance, you’ll have the option to skip for a normal restart, or when you select a boot device while you might have to enter the password for unattended reboots or when your PC is powered on, etc. And if you are here to remove the password, you need to find a remove password option in the same section. You will be prompted to enter the set password once and if it’s correct, it will remove the BIOS password. After that, you have to save and exit the BIOS then restart your computer and check if the settings are properly applied.

You might also find it useful to check the System Log available in the Event Viewer for other error messages that can help you figure out the driver or device that’s causing the error. Running hardware diagnostics can also be useful.

Method 2 – Disable (or preferably uninstall) Software Before Upgrading

If you’re upgrading Windows 10 from Windows 7 or Windows 8.1, you might need to disable or uninstall the software first. First, try uninstalling your Antivirus utility before starting the upgrade. Restart a few times before starting the Windows 10 installation. If you’re upgrading using the Windows 10 update, make sure that you disconnect from your Wi-Fi or Internet LAN (Ethernet) connection as soon as the download reaches 100% before attempting to start the set-up. Other users also reported that the cause of the KMODE_EXCEPTION_NOT_HANDLED issue is BitDefender. If this is what happened in your case, it will show in the error message such as KMODE_EXCEPTION_NOT_HANDLED (bdselfpr.sys). Users reported that a common solution for this is renaming the file. In the case of BitDefender, try renaming it to bdselfpr.s__. However, make sure to do this cautiously. Sometimes, renaming a file will even do more damage than good.

Method 3 – Disable/Disconnect From Hardware

Method 4 – Other Troubleshooting Steps

Other troubleshooting steps include:

• Upgrade using an .ISO file, instead of directly upgrading from Windows Update. When you do this, make sure you’re disconnected from the Internet during installation. If the process started and you forgot to disconnected, it’s best to restart the installation.
• If you’re connected to a domain while trying to set up Windows 10, disconnect and use a local account.
• If you’re using a SCSI hard disk, connect a thumb drive with the drivers for your storage device. While Windows 10 is setting up, click on the Custom Advanced Option. Using the thumb drive, use the Load Driver command to load the SCSI drive.
• Another possible cause of this error is due to BIOS incompatibility. BIOS issues can be solved by upgrading your version of your system BIOS. If you don’t know how to do this, refer to your BIOS manufacturer’s website.
