When Windows is installed on a clean hard drive it usually finds most of the needed drivers for our computer to run, but if we by any chance have any old unsupported hardware or some exotic one chance are very high that Windows will not be able to locate and install drivers for it. And sometimes we do not even have drivers from where to download them, let's say for example you have purchased a second-hand laptop with Windows on it, you wish to create a clean and fresh copy of new Windows installation but you do not have drivers, and let us say the model is not supported so you can not download them. In this case, this shown method will help you a ton and save you a lot of time and frustration. So, in order to back all of your drivers from your Windows follow this simple guide step by step. Note please that this method will backup drivers themselves, you will not backup installation packages of drivers or similar stuff, only drivers installed in Windows itself.

Backing up the drivers

First thing first, create a folder where you want your drivers to be backed up somewhere in your HD and give it any name. Second, press ⊞ WINDOWS + X to open the secret Windows menu. From the menu choose Command Prompt (administrator) When the command prompt is active type the next command in it: DISM /online /export-driver /destination:C:\DriverBackup where: C:\DriverBackup is the folder and the hard drive where you want to store your backed-up drivers. Press ENTER That's it, you have now successfully backed-up all of your installed Windows drivers. Now, save all of your drivers on USB and reinstall Windows.

In order to now return backed drivers do the following:

Press again ⊞ WINDOWS + X to open the secret Windows menu. but this time choose Device manager From decide, manager right-click on any device Windows has not been able to install appropriate driver and choose update driver

When you try to open your Google Chrome browser and it starts to connect to the internet but suddenly, your Windows 10 computer crashes along with a Blue Screen error that says, “MEMORY_MANAGEMENT”, then read on as this post will guide you in fixing the problem. This kind of BSOD error occurs when Google Chrome requests more memory or when it tries to access the network and demand is raised for more memory, the memory management program fails. To fix the problem, here are some possible solutions you might want to try. Follow them thoroughly.

Option 1 – Use the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues. And since the MEMORY_MANAGEMENT Blue Screen error concerns Google Chrome and an internet connection, the root cause of the problem might have something to do with the Network driver and to verify that, you can use the Driver Verifier Manager:

• Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
• After that, select the option “Create custom settings”.
• Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
• Next, select the option “Select driver names from a list” option.
• Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
• Then click on the Finish button.
• Open Command Prompt as administrator and execute this command – verifier /querysettings
• The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
• Open the Command Prompt as admin again and run this command – verifier /reset
• The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 2 – Try updating the Network drivers

• 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.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the MEMORY_MANAGEMENT BSOD error.

Option 3 – Try disabling Hardware Acceleration

You might want to disable Hardware Acceleration system-wide or for a particular program like Google Chrome and see if it resolves the MEMORY_MANAGEMENT error

Option 4 – Run the Memory Diagnostic Tool to check for Memory leaks

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Option 5 – Perform a System Restore

Performing System Restore might help you in fixing the SYNTP.SYS Blue Screen 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.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like MEMORY_MANAGEMENT. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

What software are you using to keep your information and all your files and memories safe? 

None? Yikes. Let’s hope no damage has been done to your data yet then. Because with how the digital world has evolved, your data might be getting leaked and you have no idea.

Why do you need to invest in security software?

There’s really no good excuse not to purchase a quality platform for PC protection. Especially since top security solutions are available at such affordable prices nowadays, your wallet would barely even notice it.

At this point, only people who barely use their PCs and have zero sensitive information on them can get away with simply using the built-in Windows 10/11 security software. But we guarantee that those people are extremely hard to find and that you’re not one of them, and here’s why.

Even if you don’t use your computer for things that are very obviously sensitive, such as internet banking, you still have some personal data at risk of being stolen. How so? Well, think about the data you enter into your social media profiles, for example. How devastating would it be if somebody got a hold of any of it? Yep, that’s what we thought.

In the hands of a skilled cybercriminal, your phone number alone could put you at risk of scams, ransomware, identity theft and more. Also think about the stuff you share in texts and social media chats. Think about the websites you visit and how many times you may have accidentally clicked on an ad, which could very well contain malicious software. Those all seem harmless until someone’s actually used them against you. 

Now imagine the dangers involved when you actually store truly confidential data on your PC and browsers. Sends shivers down your spine, doesn’t it?

In the case of a successful cyberattack of whatever type (virus, phishing, worms, etc.), there’s so much that is at stake. Businesses/legal persons will suffer from financial loss and damaged reputation, at the very least. Natural persons may be threatened or exploited, get their banking or medical information and even their identity stolen, etc. And that’s just the tip of the iceberg.

These are our biggest reasons for investing in Windows PC protection software:

• Cyberthreats are constantly evolving to the point where built-in or free software won’t cut it anymore.

• Those working remotely can have peace of mind knowing both personal and business data is completely secure.

• Businesses using top security solutions ensure their customers trust them. 

• Data breaches are a pain in the you-know-what to handle. Fighting a cyberattack and going back to normal is a demanding process, and not to mention the stress it’ll cause. We’d rather prevent all that by using trustworthy security products!

• It helps parents worry a little less about their children’s safety in the online world. 

• Added bonus: with most products, you get an ad-free browsing experience!

Obviously, there are a lot more reasons to get your PC secured. But we think you get it. So let’s cut to the chase and take a look at our 6 favorite protection solutions and the wonders they can do for you.

*Note that in this article we’re looking at products primarily suited for households and home offices, some for small businesses. No enterprise solutions will make the list today, but stay tuned for a future article on those.

Top 6 best PC protection solutions

1. Bitdefender Total & Internet Security\

One of the biggest security product vendors out there, Bitdefender offers several awesome solutions. We want to introduce two of our favorites, Bitdefender Total Security and Bitdefender Internet Security.

Bitdefender Total Security is great for both households and smaller offices. You can choose to protect 5 or 10 devices, and not necessarily just Windows devices. It also works for macOS, Android and iOS. It offers a range of powerful features, such as:

The latter means the software notifies you if any of your personal information is found on the dark web, which helps protect you against identity theft.

5. McAfee Antivirus

Don’t be misled by the name of this product. Antivirus software may have started as protection against viruses only, but it’s developed quite a lot. The name simply stuck. All that to say that McAfee Antivirus - another award-winning security solution - protects you against several different threats.

The basic and essential plan allow 1 and 5 devices respectively, while McAfee+ Premium and Advanced work on an unlimited number of devices. The latter two also offer more capabilities, as you can imagine. Here’s what you can expect from all of them:

The previous Windows versions all came with Microsoft's browser Internet Explorer. A lot of users love it because not only that it is easy to use. It is also very fast. Users didn’t have to worry about compatibility because it is almost always compatible with its Windows Version. When they introduced Windows 10, they changed the name of the browser from Internet Explorer to Microsoft Edge. It is faster and more user-friendly compared to its predecessors. But after the Creator Update, some experienced receiving the inet_e_resource_not_found error code. In contrary to what everyone expects, you actually don’t have to uninstall and reinstall the Microsoft Edge App. What you can do is reset the browser in your Apps & Features Settings in your Microsoft Settings.

To reset the browser you can follow the steps below:

1. Click on the Windows icon and go to settings.
2. Click on Apps and this will bring you to the Apps & Features page. Look for Microsoft Edge from the list of Apps and click on it.
3. Choose Advance Option
4. Scroll down then Under Reset, click on repair or reset. When you repair it will fix the existing problem but the data that caused the problem may still be present and can still cause problems. If you click on reset, it will delete all the cache and cookies that are installed in your browser but it will save your Favorites as well as your bookmarks.

Another way to resolve this is by disabling the feature TCP Fast Open on Microsoft Edge. To disable this, go ahead and follow the steps below:

1. Open the Microsoft Edge browser.
2. Type in about: flags on the Address (URL) bar.
3. Under Networking, uncheck the Enable TCP Fast Open.
4. Close your Microsoft Edge browser and open a new one.

Flushing the DNS also worked for other Users. Sometimes, the error code the inet_e_resource_not_found is caused by a corrupted DNS cache. There are 2 ways to flush your DNS. The first option is to use the command prompt to run the command.

1. To access the Command prompt or CMD, you can search for it on Cortana or you can click on the Windows icon to access the Programs, scroll down to the Windows System folder and click on it.
2. A dropdown menu will show up, click on Command Prompt which is the first on the list.
3. Type in the code ipconfig /flushdns and press enter.
4. There will be a message that will show that says Windows IP configuration successfully flushed the DNS Resolver Cache
5. Exit the CMD by typing exit and press enter.

The easiest way to do this is to Press the keys Window + R on your keyboard. Type in ipconfig /flushdns in the search box and hit enter or click on OK. These are only some of the ways to resolve the inet_e_resource_not_found. There are other ways to further troubleshoot this issue such as reinstalling your Wifi Adapter Driver or adjusting the DNS Server Address. But most of the time, users are able to resolve the issue with the steps provided above.

A lot of programs in Windows utilize the helper processes to ensure that they can get the job done as early as possible. And one of the programs that use these processes is Microsoft Edge. This built-in browser uses a process called the Edge Content process. The moment you start your computer, these system processes are loaded which makes the Edge browser load faster. To be specific, these are the three processes that are related to Microsoft Edge:

• MicrosoftEdge.exe
• MicrosoftEdgeCP.exe
• MicrosoftEdgeSH.exe

The process that ends with the “CP.exe” is the content process in Edge. However, when this process stopped working, this can affect the Edge browser. In such cases, when you check the Reliability Monitor, you will see that the state of the “Microsoft Edge Content Process” is “Stopped working” which keeps on appearing. To resolve this issue, you can try to clear the browsing data of Microsoft Edge or repair or reset it. You can also try re-registering Edge via Windows PowerShell as well as check your security programs that might be causing interference with the process.

Option 1 – Clear the browsing data of Microsoft Edge

• Open Microsoft Edge.
• Then click on the three horizontal dots to open the menu.
• From there, click on Settings. And under Settings, click the “Choose what to clear” button under the Clear browsing data section.
• Next, check all the checkboxes and then click the Clear button to clear the browsing data in the Edge browser.
• Restart Edge.

Option 2 – Try to reset, repair or reinstall Edge via Settings

You can reset, repair or reinstall the Edge browser through Settings. If none of it helped, you can try the following:

• Open File Explorer and then go to this path – C:/Users/YourUsername/AppData/Local/Packages

Note: Before you type in the path in the Address bar, make sure that you put your user account name in place with the “YourUsername”.

• Tap Enter to proceed.
• Next, look for the folder named “MicrosoftEdge_8wekyb3d8bbwe” then right-click on it.
• Click on Properties and uncheck the option “Read-only” under the General tab in the Properties window.
• Click on Apply and then OK to save the changes made.
• After that, look for the MicrosoftEdge_8wekyb3d8bbwe folder again and delete it. And if a prompt stating “Folder Access Denied” appears on your screen, just click on the Continue button to proceed – doing so will delete most of the content inside the folder except for the folder named “AC”.
• Restart your computer

Option 3 – Re-register Edge via Windows PowerShell

• In the Start Menu, search “Windows PowerShell”.
• Right-click on Windows PowerShell from the search results and select the “Run as administrator” option.
• Type in this command in the PowerShell windows and tap Enter – Cd C:/Users/YourUsername
• After that, type in this command and tap Enter – Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml" -Verbose}
• Restart your PC.

Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppXManifest.xml” -Verbose}

Option 4 – Try to check your security program

It is possible that a security program installed in your computer is the one that’s causing the problem which is why you have to check it. According to security experts, there are some security programs that could be detecting the Edge’s content process as suspicious, blocking or terminating it as a result. Thus, you need to modify your security program’s settings to fix the problem.

What exactly is no audio device malfunction?

No audio device error is among the malfunctions that many Computer consumers run into. No sound or audio can be heard from the computer when the error occurs.

Solution

Error Causes

There are numerous elements that may be the basis of this malfunction. Corrupted or broken sound card drivers, incorrect Device Manager Options for example, or even incorrect BIOS configurations.

Further Information and Manual Repair

How could you recover the standard production of audio by your personal computer and solve this malfunction? Like a number of additional malfunctions, the method of the repair depends on its trigger. To properly solve this dilemma, you are required to run through an evaluation of the pc system so that you can pinpoint the cause. This is because there are numerous variables, which alone, or concurrently may trigger this dilemma. These measures will allow you to work out the no sound device error in your personal computer programs, identify the trigger and fix it. Follow the directions in step 1 if your computer has an onboard audio device installed in it and assess the BIOS settings. You can jump step 1 and move to step two if you utilize a separate sound card.

STEP #1 - Assess the BIOS options.

No sound device error can be caused by incorrect BIOS configurations in your Personal Computer. By fixing these settings if they are the cause of the malfunction, you can easily solve it. Make Sure you restart the pc and immediately access the BIOS options. By locating the Sound card, which is usually known as the AC97 Audio, you should subsequently open the Integrated Peripherals. As soon as you locate it, set it to Allow or Auto. Finally, you should access the On-Board Audio AC97 Control and set it to Allow or Auto as well. If it doesn't solve the situation, proceed to Step Two.

STEP #2 - Analyze the Device Manager

No sound device malfunction can be additionally caused by malfunctions with the Device Manager. To solve this issue, go to My Computer, right-click it, select properties, click on the Hardware tab, then click on Device Manager. At this windowpane, analyze the movie, audio, and game controllers. If you learn that there is a cross on any of the sub things, right-click it subsequently and set it to Enable. The sound card driver may have not been correctly installed or may be damaged if there is Exclamatory Mark or Question Mark on the device manager menu. This does not mean that the sound card driver is ok. It may have malfunctioned even though you do not locate anything unusual. This is because the Device Manager doesn't always recognize errors in audio hardware. After this, you can proceed to step 3.

STEP #3 - Upgrade or reinstall the Sound Card Driver.

About 80% of "no sound system discovered/installed" malfunctions come from broken and/ or out-of-date card drivers. The sound card will not be detected by the Windows Operating System, when the audio card driver is corrupted, damaged, or out-of-date and therefore no sound will be produced by your computer. If this is the cause of the no sound device malfunction, you should reinstall the Audio Card Driver on your computer. Still, you can utilize driver upgrade applications on the web that will help you upgrade out-of-date drivers.

One of the biggest annoyances in Windows 10 is that it’s upgrading from one version to another. Although these upgrades are necessary to fix some bugs or improve user experience, some of them actually bring bugs into the computers instead. And in one of the recent Windows 10 updates, a lot of issues were found especially for users who use Remote Desktop on a daily basis. The error stacks up as Windows 10 Remote Desktop Protocol client is not working or won’t connect and can’t find the computer HOSTNAME generally. Based on the reports by users who experienced this issue, there are two cases around it:

1. Users who try to reach a specific website or folder on the network

Some users encounter this error when they try to run the Network Troubleshooter. Even when they add the server name inside it, it still won’t identify the problem, and unpredictably, the driver seems to appear and disappear every now and then. And even after connecting, the network commands don’t work at all. This is really troublesome for users who have lots of PCs and all the other systems do not appear on the network.

2. Remote Desktop isn’t able to find the computer HOSTNAME

Some other users reported that the error appeared when they use the classic remote desktop software. It keeps on failing and throwing the error message, “Remote Desktop can’t find the computer “HOSTNAME”. If this is the same scenario you are having, it means that “HOSTNAME” does not belong to the specified network. So you need to verify the computer name and domain where you are trying to connect to. There are times when it used to work after some users tried connecting to the domain a couple of times. However, when users try to use the UWP version of Remote Desktop, it seems to connect most of the time. This kind of problem is definitely a DNS issue. It could be that there are two different records on the DNS server which is why it connects and other times it doesn’t. When it is able to resolve the correct address, the drives connect to the PC however, after a couple of minutes, they will suddenly go missing. Using “nslookup” for the hostname, multiple times, you can check this and see if you’ll get identical results all the time.

nslookup [–SubCommand …] [{ComputerToFind| [–Server]}]

If you’ve determined that the drives disappear each time, you may have to change the DNS server or ask your admin to resolve the problem for you. Alternatively, you can also check out another option that has worked for a lot of users. This second option is disabling the IPv6 on the network adapter. In case you don’t know, Windows 10 prefers IPv6 over IPv4 so if you now have issues using IPv6 to connect to the servers, you can change your computer’s settings so that it’ll only use IPv4 instead of IPv6. To do so, follow these instructions:

• Open Settings > Network and Internet > Ethernet > Change Adapter options.
• From there, right-click on the adapter for where you want to disable it and then select Properties.
• Next, look for the checkbox labeled, “Internet Protocol Version 6 (TCP/IPv6)” then uncheck it.
• Now click on OK and restart your PC to save the changes made.
