Method Three: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

Seeing a yellow triangle with an exclamation mark on the battery symbol on the System Tray of your Windows 10 laptop is not really uncommon especially if your battery is about to run out of power. However, if you just purchased your laptop recently and the first thing you’ve noticed when you first opened it is the yellow triangle with an exclamation mark in the battery, read on as this post will help you resolve this issue. Seeing this kind of icon on your computer does not necessarily mean that you have to replace your battery as there are still several potential fixes you can try to resolve the problem. So if you notice this icon, you can try running the Power troubleshooter as it will help you resolve any potential issues with the battery. Aside from that, you can also restore the default settings of the power plan manually or uninstall and reinstall the battery driver. For more information, refer to the given options below.

Option 1 – Try to run the Power troubleshooter

As pointed out, the Power troubleshooter can help you resolve any issues your battery might have automatically. It plans and detects system settings that can affect power usages like timeout and sleep settings, display settings, and screensavers and restores them to their default settings. To run this troubleshooter, follow these steps:

• Open the Windows Settings and go to the Update and Security option.
• Next, click on the Troubleshoot option under Update and Security and then scroll down until you see the “Power” option.
• Under Power, click on the “Run the troubleshooter” button to start running the Power troubleshooter.
• Wait for a couple of seconds until the Power troubleshooter is done scanning your computer for issues. Once it’s done, follow the next on-screen instructions that appear on the screen.
• If needed, restart your computer and see if it has fixed the problem.

Option 2 – Restore the default settings of the Power plan manually

• Open the Windows Settings again and select System.
• Next, scroll down until you see the “Power & sleep” option.
• After that, click on the “Additional power settings” option located in the right pane to open the Power Options.
• Now click on the link that says, “Change Plan Settings” and select the “Restore default settings for this plan” option.

Option 3 – Try to uninstall or reinstall the Battery driver

You might also want to uninstall or reinstall the battery driver as it can also resolve the problem. But before you start, you have to shut down your computer and remove the power chord as well as the battery. Once you’re done, follow these steps:

• Plug the power chord and restart your computer.
• Once your computer has restarted, tap the Win + R keys to open the Run utility and type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After that, look for the “Batteries” driver from the list of drivers and expand it.
• Then right-click on the “Microsoft ACPI-Compliant System” driver and click on the “Uninstall device” option.
• Once it’s done, restart shut down your computer and remove the power chord and then attach the battery.
• Now attach the power chord again and restart your computer to automatically install the driver.

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.

As we near the end of 2022 we look at the current best antivirus software for popular platforms, why they are the best, and why you should get them.

Avira, a great free Antivirus

Avira has been around a long time with its free antivirus version of the larger protection suite. It had its ups and downs but the latest versions are really great. With high-speed scans and low system impact, Avira antivirus is really one of the best free antivirus software currently on the market.

The software itself has also received UI & UX updates making it straightforward and easy to use. The virus scanning engine is the same as in paid version that ranks among the top engines in the world for this type of work. The package also gives you some great browser protection and a good firewall as well, there is really no excuse to skip on this if you want a free solution.

The only thing that we would say is not so great in Avira is reporting some false positives, sometimes even for MS updates, it is rare but it can happen.

Malwarebytes, a powerful Windows antivirus

Malwarebytes Premium is easy to use, simple antivirus solution that shies away from complicated UI, and simply put, it just works. Its scanning engine is well-known and places among the top and best in the world often finding some malware that other can miss.

Another great thing is its integration with Windows itself, it is one of the rare applications that can and will work incredibly well beside your typical Windows protection tools so you can have both of them running at the same time.

Installation and running are really simple and every typical PC user will find it as easy as walking in the park. On the other hand, sadly system impact is a little high and it will have issues running on lower-end systems due to its memory requirements.

Intego MAC Internet Security X9, the best Mac antivirus

Gone are the days when MAC had no virus issues, since MAC rose in popularity among the users, also rose the number of viruses and malware. The system itself has some great protection built it inside but for more security and better control of it, you will need a third-party dedicated solution.

Intego was made by Mac antivirus experts who have been building this kind of software last 25 years. The interface is easy to use and premade presets are really helpful, but the security suite can also be customized to fit your needs and desires.

Since this is only available as a security suite, you are getting a firewall and some other security tools along with your antivirus that will run as a part of it.

The bad side is that scans can sometimes run slow, most of the time they are OK in terms of speed but occasionally they can switch to slower speeds and impact scanning time to some annoying times. Also, there is no webcam protection nor VPN service included where others on this list have them.

Bitdefender mobile security: best Android protection

While protection is not only needed for your gaming or workstation, software suites that are dealing with mobile and tablet security exist. The best of them is the Bitdefender antivirus mobile suite. Low on system resources and low on performance impact with the really great virus detection rate Bitdefender is at the top of suites for your phone.

Consistent high virus detection packed with low battery impact is great but the suite comes with tons of other tools as well like browser security tools, email protection, and real-time link and notification protection.

The application will always scan each file and newly installed application in the background and alert and cut off any found threat. App itself is easy to install and use and most of the time it will do everything in the background for you but offer you customization if you need it.

The package also includes VPN and application lock that will let you protect the critical applications from being accessed as well as an online account scanner. Anti-theft and anti-loss tools, which allow you to find, remotely lock or wipe a stolen or lost device, add yet another layer of protection.

One thing that is missing from this great package is fraudulent call protection. Newer Android phones have this feature inside but it would be nice if Bitdefender had it as well.

Bitdefender, the best antivirus software

Now that we have covered specific cases of each platform, there is one player that has all of them covered and with a quality product, that player is BitDefender and it is great. Personally, this is my protection suite of choice and as I type this it is running in the background.

Bitdefender has it all, low system impact, as a matter of fact, it is one, if not, the lowest performance impact engine on the market currently and that is packed with a great and highly consistent virus & malware detection suite. Along with real-time malware protection, browser security, and anti-spam tools, you also get anti-phishing defenses, ransomware protection, and a strong firewall.

Bitdefender scores are very high in both the zero-day threat and real-world protection tests at AV-Test, an established organization that tests antivirus software. Despite being tested against tens of thousands of well-known and widespread malware threats, the software consistently achieves a 100% blocking rate.

The suite also comes with a restricted free VPN and with parental controls as well. Webcam and microphone protection are also included in the suite and on top of all, it has great pricing plans and constant discounts.

BitDefender is really a great package and it might sound too good, but after years and years of personally using it I have not had single malware or virus issue, the only thing that I would put as a negative is that system is severely slowed down when system scans are performed so be sure to run or schedule them when you are not using your computer. This, of course, can put some people off and I will admit it is a serious drawback but for me, the security of my workstation is more important than leaving the computer for 20 or so minutes in order to perform a full scan of the system.

If you encountered an error message saying, “We couldn’t find any drives, To get a storage driver, click Load driver” when you try to install Windows in a VirtualBox machine, then you’ve come to the right place as this post will guide you in fixing this error. This error message is displayed on the screen where you have to choose a partition to install the guest operating system. This error is most likely due to the lack of correct settings as well as a corrupted virtual disk. To fix this error, you have to remove existing storage devices, create a new storage device and select the correct ISO file.

For complete instructions, follow the given steps below.

Step_1: The first thing you have to do is remove all the existing Storage devices and since this option is already available in VirtualBox by default, there is no need for you to install any third-party software. Step_2: After that, open VirtualBox and select the virtual machine and then click the Settings button. Step_3: Next, switch to the Storage section and on your right-hand side, you will see “Controller: SATA” and two other sub-labels. From there, select Controller: SATA and then click on the red cross button that says, “Remove selected storage controller”. Step_4: Now click on the Add new storage controller icon and select the “Add SATA Controller” option from the given list. Step_5: Afterwards, click the “Add hard disk” button and select the “Create new disk” option, and then you have to create a new virtual disk for your virtual machine. Step_6: Verify if you have selected Dynamically allocated while you create the virtual hard disk. Once the process is completed, you will get a “.vdi” file in the list. Step_7: Next, click on the “Add optical drive” button and select the “Choose disk” option. Here, you have to select the ISO file and if you can find an ISO file in the given list, select it from there, else, you have to click the Add button and navigate to the folder where the ISO file is located. Step_8: Once you’re done, click the OK button and boot your virtual machine. You should see options instead of the “We couldn’t find any drives, To get a storage driver, click Load driver” error message. If you see the options, you can now create a new partition and start the installation process of the Windows operating system in the VirtualBox machine without any problem.

When we are working on our computer, we have tendencies to make it look and behave to our best needs and however, best suits us. The Internet has crawled into our lives and made itself a must-have in modern society, internet browsers as a crucial piece of software for viewing the web have also grown and made themselves to be more open for user settings and personalization, Chrome, one of the most popular browser has the option to open a specific set of pages one it is opened and that is what we will cover today in this tutorial. No matter would you like to by default open some online store, maybe an email or news website, you can open each of them or all of them once Chrome is run, making your daily routine more enjoyable and stress-free. The first thing, of course, is to start Chrome itself, once Chrome is up, click on three dots in the upper right corner of the Chrome window and select settings. When you are in settings, on the left side move toward the bottom until you run into a tab that says On Startup and click on it. On right, a new section will open, click on Open a specific page or set of pages. You will be presented with the option to add a new page by typing its URL or getting it from bookmarks or using a specific opened one. You can repeat this process until you have added all pages that you wish to be automatically opened once Chrome is opened for the first time.

BONUS:

If you have noticed right above the setting that we have used for opening a specific set of pages there is the option Continue where you left off, this option will open each page exactly where it was when Chrome was shut down letting you keep viewing where you have left off. This is useful if by any chance your battery ran out or you had to quickly turn the computer off for whatever reason.

TPM or Trusted Platform Module version 2.0 is a must-have if you plan on upgrading your system to Windows 11. So what exactly is TPM and do you have it?

What exactly is TPM?

TPM is a tamper-resistant hardware technology tasked with generating and storing encryption keys inside it for better PC security. It can be remotely used to authenticate hardware and software by utilizing a unique endorsement key placed into the hardware itself. This technology can be used for example in BitLocker inside Windows in order to have data on a hard drive encrypted so if the mentioned drive is connected to another computer it would not be able to be accessed since the encryption key is stored in the TPM module. Microsoft is pushing its agenda that Windows 11 must be and must feel like safety first OS which will protect user data and user information and requiring TPM means that each Windows 11 will be secure so no additional software patches will be required for an extra layer of security. Windows 11 will assume that each user has TPM encryption enabled and will be built upon that.

Do you have TPM on your computer?

If your computer or hardware has been purchased in 2016 or later there are very high chances that you already have the required technology to run Windows 11. Unfortunately, many gaming motherboards have not been placing TPM in their boards and you might not have it. Also, there is the option of you having it but it is turned off in motherboard settings making Windows unable to detect it. As you can clearly see there are a lot of scenarios around required tech and honestly it is a complete mess. But lucky for you there are ways to find out do you possess the needed module in order to make an upgrade. On your current computer on which you would like to make an upgrade in your current Windows OS press ⊞ WINDOWS + R to open the run dialog. Inside run dialog type in TPM.msc and press ENTER to open Trusted Platform Module Management on Local Computer. You will immediately receive information do you have the required module. If everything is fine, you are good to go, however, if it says that compatible TPM cannot be found there is a chance that either you do not have needed hardware or it might be turned off inside motherboard settings.

Check motherboard UEFI

If you have a newer motherboard but Windows utility cannot detect TPM there is a chance that it might be turned off directly on your board. In order to check this, you will have to boot up your PC into UEFI either by pressing the corresponding key when it is turned ON or from Windows reboot options. Once you are inside UEFI you need to find security options and see if there is an option to turn ON or enable TPM. Since every motherboard is different and has different UEFI software we cannot cover all of the permutations and the best we can do is hope that provided information is enough. You can also visit your motherboard manufacturer to see instructions for your specific case.

Conclusion

TPM itself is generally an OK idea and I can surely see good sides of it but there is this lurking feeling that generally, Microsoft is not really concerned about the security of our data and that the real requirement for this is trying to battle software piracy. I simply cannot trust company which introduced tons of telemetry tracking through ages and which has done everything in their power to battle non-legal use of their software. I do not promote piracy but I support free choice and besides, who can tell me what will happen if TPM malfunctions, will I lose all of my data forever? It is not so uncommon that TPM has malfunctioned in the past and it is only logical to presume it can do it again in the future but this time we will not have the choice not to use it, we will be forced into it.

What Is 0x80004005 Outlook Error?

0x80004005 Outlook is an error that users commonly encounter while attempting to send or receive emails on Outlook.

The message that appears usually states “This message could not be sent. Try sending the message again or contact your network administrator."

The client operation failed. Error is [OX80004005- 0X0004B9-OXOO501].

Error Causes

This error is usually caused by a problem in the Local Area Network or LAN. What actually happens is that signals with the wireless LAN are lost or a connection problem occurs within the network cable.

As a result, the 0x80004005 Outlook error is triggered while sending or receiving an email. Sometimes the problem goes away on its own. However, if it recurs after a few hours, it shows that some problem exists within the network.

Also, it is important to understand that different factors can affect the quality of wireless connections in a network.

For instance, garage door openers, microwave ovens, and Bluetooth devices can easily become obstacles, disrupting the connection and causing the quality to degrade. Other causes are listed below as follows.

• Missing, corrupt, or damaged registry keys
• Existence of viruses
• Outdated drivers

It is a must to fix this error otherwise potential risks associate with this error such as permanent damage and blue screens.

Further Information and Manual Repair

There are two ways to fix this error and both are listed below as follows.

• One solution is to disable script blocking in Norton Antivirus. Most users encountering this problem have Norton Antivirus installed on their PCs. To correct this problem, simply turn off the ‘Enable Script Blocking’ feature. However, there is a downside associated with this solution. Enabling script blocking will make your network or computer vulnerable to viruses and malware. That’s why it is not advised to implement this solution.
• The alternative solution is to simply disable the new-mail notification feature offered in Outlook. To disable notifications of any new emails, the steps go as follows. Open Outlook and go to the Tools menu. Here you will come across ‘Options’.Click on it and then select the ‘Preferences’ tab. Here you will find the ‘Email Options’. Click on it and then uncheck the checkbox against the option, ‘Display a notification message when new mail arrives’. Click Ok two times.

Both these workarounds will work. Therefore, it is advised that you employ any one of them as per your needs.

If you are running the Windows Update service but decided to stop it but you encountered an error message instead that says, “The Windows Update service could not be stopped”, read on as this post will help you fix the problem. This kind of error appears when you use the Command Prompt to stop the Windows Update service, especially if you are using cmd without admin privileges. A lot of users reported that they were not able to disable the automatic Windows Update in Windows 10 using Command Prompt. The command used to stop the Windows Update service is the “net stop wuauserv” command. However, when some users executed this command, they got the error message. So if you are one of these users that can’t stop the Windows Update Service via Command Prompt, you can try to fix that using PID as well as checking the Service dependencies. For more details, follow the given options below.

Option 1 – Try to stop the Windows Update service via PID

In case you don’t know, each running service or process has its own unique ID or PID and you can find it in the Task Manager. You can use it to stop the Windows Update service. How? Refer to these steps:

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Services tab and look for the service named “wuauserv” and get its PID.
• After that, type “cmd” in the Windows Start search and right-click on Command Prompt from the search results and then select the “Run as administrator” option.
• After opening Command Prompt with admin privileges, execute this command: taskkill /f /pid <PID>

Note: You need to replace “<PID>” with the PID of the “wuauserv” service. For instance, the PID is 6676, then this is how the command should be “taskkill /f /pid 6676”.

• After you execute the command, you will this message on your screen, “SUCCESS: The process with PID 6676 has been terminated” which indicates that you have stopped the Windows Update service successfully.

Option 2 – Try to check the Service dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Error Code 0xc00007b – What is it?

Error code 0xc00007b usually manifests itself via the inability to start an application properly. It can occur when users attempt to run a game or other programs on their computer. In such a case, the application will not start and a message box will pop up stating that error code 0xc00007b has occurred. The error code is likely to occur when users attempt to run a program in the incorrect or inappropriate bit. For instance, if you try to load a 32bit location with a 64bit location.

Solution

Error Causes

Error code 0xc00007b affects various versions of the Windows operating system, including Windows 7, 8, 8.1, and Windows 10.

Microsoft DirectX is an application usually included in the Microsoft operating system. It enables users to access high-speed gaming and multimedia on their PC. The latest version of this Windows technology is available on Microsoft’s official site.

Note that this solution should only be applied if you are having issues running or displaying a gaming or multimedia application.

If you are still unable to run applications after completing this manual repair procedure, however, you will need to apply another method to fix error code 0xc00007b for Windows 10.
