Windows Updates failed to install, 0x80073701

Have you been feeling anxious in the digital space? Feeling like you have a million eyes on you each time you visit a website? It can definitely make you uneasy. Luckily there’s an easy fix, and it’s called a VPN.

In this article we’ll take you through the basics of what a VPN does and some of the biggest benefits you can reap from buying one.

VPN: definition and how it works

VPN stands for Virtual Private Network, so its name already says a lot about what it does. 

A VPN is specialized software that keeps your browsing private and secure. Essentially it hides your identity, preventing possible cyberattacks and data theft. This is especially important in cases of public network use, where you’re highly exposed to potential threats.

To be more specific, this software encrypts your Internet Protocol (IP) address by filtering it through a server hosted by the VPN provider first. That way, it prevents your Internet service provider, third parties and lurking online thieves from tracking the actual you.

Some providers, such as Surfshark VPN with its IP Rotator feature, even make it a habit to frequently change your IP address to further protect your identity. With most VPN providers, you can also appear to be in a completely different country, adding to your disguise.

There are tons of advantages you can look forward to if you decide to use a VPN. Take a look at some of the crucial ones.

Benefits of using a VPN

When choosing a VPN, you can find both free and paid options. We recommend you go with the paid ones, since they have stronger security, encryption and data protection, as well as more advanced features. Free VPNs come with limitations and risk of malicious attacks on the software itself.

You can choose to buy a singular VPN service or opt for antivirus software that has a VPN built in, for example Bitdefender’s Ultimate Security plan. That depends on what you use your computer for and how much. 

When you pick one, here’s what it can do for you.

1. Access region-specific content

When we said you could change your location, we meant it. Say you’re using a streaming service and a show you desperately want to watch isn’t available in your country. You can use your VPN to make it look like you’re browsing from a country where it’s unlocked.

This option is also convenient for gamers who want to access maps, skins and other in-game items unavailable in their location.

In addition, you can use this powerful feature when you’re traveling to a region where some of your favorite content may not be accessible.

Do keep in mind that you need to read the Terms and Conditions (yeah, we know - who does that?) of your games and services before doing this, since you could end up getting a penalty. It’s also important to remember that there are entire countries that have strict regulations or even bans on VPNs, for example Belarus, Russia and China. So make sure to be very cautious with your VPN use, friends.

2. Browse like no one’s watching

VPNs shield your browsing habits from prying eyes on the web. Those can be malicious hackers or just third-party cookies tracking your every move to later bombard you with targeted ads. For example, Surfshark VPN features a Cookie blocker that blocks all cookie-related pop-ups and lets you browse in peace (and secret). It works even when the VPN is turned off, which is also pretty neat.

In addition, their CleanWeb 2.0 technology makes sure ads and especially malware don’t stand a chance at all, since they’re blocked before they can even load.

The inability of sites to track your browsing means they can’t collect and analyze any of your data. So, your personal information - or your company’s information in case that’s what you’re using your computer for - is entirely hidden and secure.

3. Save money

It’s well-known that the prices of certain items and services vary based on your location, browsing time, age and many other factors. This most commonly goes for airline tickets and hotel stays.

You can use your VPN to avoid high prices and surcharges. Clear all cookies, turn on your VPN and visit an online shopping site to check out their prices. Then compare your findings with the offers you see when your VPN is off, when you spend a long time on the site or have an active account with the company. 

Sometimes this can really help you find the best deals and avoid breaking the bank. But again, check the Terms and Conditions before you purchase something using a VPN.

4. Secure your smart home

The more smart devices you have connected to your network, the more exposed you are to potential cyberattacks. Phones and computers are generally designed to be decently secure even without a VPN or antivirus, but smart home devices leave a lot to be desired in that regard. 

Protecting your home network with a VPN software means all devices connected to it are secure, be it an air purifier or Alexa.

5. Prevent connection slowdown

Your ISP can intentionally slow down your internet speed based on how much data you’ve consumed (data throttling) or your activities online (bandwidth throttling).

But with a VPN, what kind of data you send and receive and how much is entirely hidden. Therefore, if your ISP can’t see you, they can’t control you and they can’t throttle down your speed.   

The bottom line

You can never be too safe online. So definitely think about getting yourself a solid VPN to pump up your privacy and security as much as you can. And if you have any questions or need help choosing the perfect software for you, feel free to reach out to us.

DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files. In this post, we will be discussing one DLL file called ntdll.dll. It is described as “NT Layer DLL” which means that it contains some Kernel functions that help in the normal functioning of the Windows operating system. It is created by Windows in the System32 folder when the OS gets installed. This file can serve different programs simultaneously by providing them with different Kernel functions which support the programs’ performance.

Lately, some users reported getting an error that says, “System doesn’t have any USB boot option, Please select other boot option in Boot Manager Menu” when they tried to reinstall the Windows 10 operating system on their PCs or boot from an installation media. If you have the same problem, then this post should help. This kind of error is applicable to multiple devices by various OEMs and is mostly due to the Secure boot being enabled, or the Legacy or CSM support being disabled. It could also be that the bootable USB device was not correctly made and so on. Whatever the cause may be, here are some suggestions you need to check out to resolve the “System doesn’t have any USB boot option, Please select other boot option in Boot Manager Menu” error and reinstall Windows 10 successfully.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the error. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try to reset the BIOS or the UEFI Settings

If updating the BIOS didn’t help in fixing Error 0199, you can try to reset the BIOS instead.

• Start your computer and tap the F10 key during the booting process to enter the BIOS. If it does not work, you can try tapping the F1 or F2 key as well as the Del key.
• Once you’re already in the BIOS, tap the F9 key to get the prompt to RestoreLoad default configuration now for the BIOS.
• Next, click on Yes and then follow the next on-screen instructions that appear to set the BIOS back to its default settings.
• Once you’re done restoring the default settings of the BIOS, restart your computer and then check if it now boots properly.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

Option 4 – Try enabling Legacy or CSM boot support

If the Legacy or CSM boot support is disabled, then it’s no wonder why you’re getting an error. Thus, you need to enable it by following these steps:

• Open Settings and go to Update & Security > Advanced Startup options.
• Next, click on Restart Now to reboot your computer.
• After that, select Troubleshoot > Advanced Options where, you will see more options such as System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• From there, enable Legacy Support and then save the changes and exit. This will restart the computer.
• Once your computer has restarted, check if the error is now fixed.

If you are typing inside the Search bar, Cortana, Taskbar, Windows 10 apps, etc., and then everything seems invisible then read on as this post will guide you in fixing this issue. At first, you might think that something is wrong with your keyboard but it really has nothing to do with it. The problem actually lies with the apps from Microsoft Store. Thus, if you can’t type anything in any of the apps from Microsoft Store in Windows 10, refer to the options given below to fix them.

Option 1 – Ensure that ctfmon.exe is running

Ctfmon.exe is a Microsoft process in Windows 10 that controls the Alternative User Input as well as the Office Language bar. In other words, it enables end-users to control the computer using on-screen keyboard inputs, speech, and even pen for various languages. It would be better if you launch the program once by going to the C:/Windows/system32 folder. Doing so will ensure that whatever API is needed for the keyboard typing to work properly again. You also have to make sure that its startup status is not disabled. In addition, you can also try the following steps, alternatively.

• Open the Task Scheduler.
• Then go to Microsoft > Windows > TextServicesFramework.
• And on the MsCtfMonitor, right-click and enable the task.
• Now restart your computer.

This will ensure that all the text boxes will start to work again. And if the task MsCtfMonitor is missing from the list of tasks, you can import it with the XML file from basics.net. Then download and create a task to run it each time you log in to your PC.

Option 2 – Use the Windows Store Apps Troubleshooter

You might also try running the Windows Store Apps Troubleshooter as it can help in resolving issues with the Windows Store apps. This built-in tool can resolve most of the app-related problems. To use it, go to Settings > Update & Security > Troubleshooting > Windows Store Apps and from there, click the start the troubleshooter button. The Windows Store Apps Troubleshooter will scan the computer for any issues with the Windows store apps and will automatically fix them if it finds any.

Option 3 – Re-register all the Windows 10 UWP apps using PowerShell

• First, make sure to close all the running applications on your computer.
• Next, in the Start search, type in PowerShell and right click on the result, and select the “Run as administrator” option.
• After that, type the following commands to re-register the Windows 10 apps. Make sure to hit Enter on each line:
  • reg delete "HKCUSoftwareMicrosoftWindows NTCurrentVersionTileDataModelMigrationTileStore" /va /f
  • get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmetadataappxbundlemanifest.xml")}
  • $bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname
  • get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmanifest.xml")}

Option 4 – Try to run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help in fixing the problem.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the System File Checker Scan

System File Checker or 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 to 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

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.

• Restart your PC.

What is OpenCandy?

OpenCandy is an application that downloads and installs software, including other Internet Browsers to a computer system. Used as a bundle, this application installs additional programs that you may knowingly or unknowingly agree to install. Since most users don’t accept the challenge of reading the EULA in its entirety, they tend to download bundled applications unknowingly.

Assessment of OpenCandy PUP

During the initial assessment of OpenCandy, I was a little skeptical about what to look out for or expect. In fact, I had to install the OpenCandy.exe file twice to discern its behavior. I’m not sure how this application got its name but I do believe it has something to do with the fact that it supposedly helps Internet users open a new world of Internet browsing. That conclusion was arrived at after realizing that OpenCandy.exe installed mostly Internet browsers along with a tune-up tool on the test computer. However, as a result of the system requirements, there was a pop-up message indicating that Internet Explorer 8 was not compatible with the computer system in question. In comparison to the malware I’ve encountered since I started researching malware, OpenCandy is everything but malicious. In fact, this application is only categorized as malware because of its’ subtle covert nature of installing bundled programs unsolicited by the user. Additionally, OpenCandy coerces users into changing their Internet Browsers by installing those unrequested by the user. In fact, it’s no shock that OpenCandy chose to install the Internet Browser ‘Opera’ as a part of this bundle since it’s one of the least used browsers according to the Federal Government. Clearly, this was a smoothly disguised advertisement or promotion to force users into using the Opera Browser, along with Internet Explorer 8.0. While these aforementioned browsers in themselves aren’t malicious and are in no way considered malware, they were installed as a promotional tool and without the request of the user. Despite being mentioned within the EULA, advertisers are capitalizing on this since most users do not bother to read the agreements when installing a program. Furthermore, OpenCandy, like most other bundled applications I’ve dealt with, threw in a tune-up tool as a part of the promotion. I found this tune-up application annoying since I had to hassle my way into getting it to close from the computer screen. I can only imagine the hassle users would go through trying to remove this software. Image 7: Depiction of a scan performed by Tuneup Utilities. The scan detected that several areas on the test PC could be optimized/tuned up. Image 8: After a scan was completed using the Tuneup utility program, I was given an option to buy the full version. Nothing is wrong with this marketing strategy. In fact, most utility tools if not all will scan your computer to detect threats or loopholes, but they won't exactly allow you to fix those problems unless you buy the full version. It's not unfair, it's just business. Programs installed during the installation of OpenCandy include:

• Web Companion: Developed by Lavasoft, Web Companion is said to be an application that serves as a security defense for your Internet browsers by preventing unauthorized changes (see image below)
• Tuneup Utilities: Tuneup Utilities does exactly as it says. It cleans up a computer system, whereby preventing unused programs from slowing it down.
• Opera Stable 30.01.1835.88: Opera is a fast, simple, and effective Internet browser that allows users to get around on the web.

All in all, the intent of installing an application such as OpenCandy is to unleash a world of promotion or advertisements on your computer. They are pretty annoying and in some cases difficult to remove. Furthermore, as a user, you want to control what gets installed on your computer without being dictated to or coerced in some EULA that you probably overlook.

BSOD or Blue Screen of Death errors are one of the most common errors you can encounter on your Windows PC. One of these BSOD errors is the “ACPI_BIOS_ERROR”. If you suddenly get this error, it means that there is some problem in booting the operating system from your hard drive or Windows was not properly installed on your PC. In addition, this error could also mean that there is something wrong with the CMOS battery located in the motherboard. Unlike other BSOD errors, the workaround for this error is a bit different as these workarounds require a bit more expertise in updating the BIOS as well as setting the correct boot configuration. If you know are capable enough in troubleshooting the problem, refer to the instructions laid out below to fix the BSOD “ACPI_BIOS_ERROR”.

Option 1 – Try to remove the SSD and update the BIOS

The first thing you have to do is to check the primary storage devices on your PC. If you have just installed a new hard drive or SSD recently on your computer, then it’s most likely the cause of the BSOD error. Moreover, you should also ensure that your BIOS is up-to-date to the latest available build.

• Remove the SSD/HDD and inject a different HDD that was already preinstalled in your Windows PC.
• After that, update the BIOS to the latest available build. After updating it, insert the old SSD/HDD and then try to boot your PC again. The problem should be fixed now. If not, refer to the next given option.

Option 2 – Try to check the CMOS battery and reset the CMOS module

As mentioned earlier, the CMOS battery might also be the one that’s causing the problem. It is a physical component of the motherboard and is a memory chip that contains all the settings configuration on your computer and is also powered by a battery. So if your battery loses power, the CMOS will be reset and as a result, all the configurations will be gone as well. It is also possible that the CMOS module is not properly working and every time things are saved, they are properly written due to the battery. That’s why you have to consider changing the CMOS battery and see if it fixes the problem. In addition, you also have to make sure that you completely reset the CMOS module and then try booting your PC again.

Option 3 – Try to check the BIOS settings

If the BIOS settings are incorrect, chances are that’s the reason why you’re getting the “ACPI_BIOS_ERROR” BSOD error. Every BIOS has different settings which you can make use of to enhance your computer experience. So make sure that your BIOS is up-to-date and that the settings are in accordance with your requirement. Another thing you can try is to disable the Legacy USB and the Legacy BIOS in the BIOS settings if you are trying to install a 64 bit Windows version. Make sure that you also enable AHCI before plugging in the installation drive on your PC. Moreover, ensure that your PC is using IDE or Integrated Drive Electronics mode instead of SATA or Serial Advanced Technology Attachment. Aside from that, try to check the extracted setup if it is in NTFS format, if it is, you should extract the ISO in FAT32 and use it to install Windows.

Option 4 – Try to reset the ACPI Compliant Control Method

ACPI or Advanced Configuration and Power Interface provide an open standard that operating systems can use to detect hardware, perform power management, as well as monitor the status of your device and provide information for other processes. Chances are, there are some misconfigurations with this module on your PC that lead to believing that there is no battery present. That’s why you need to reset it and see if it fixes the BSOD error or not.

• Boot your PC into Safe Mode.
• Tap the Win + R keys to open the Run dialog box.
• Type in “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After opening the Device Manager, go to the “Batteries” section and click it to expand it and then right-click on the “Microsoft ACPI-Complaint Control Method Battery” option and click on Uninstall.
• After you disable the module, click on any empty space and then click the “Scan for hardware changes” option.
• Then check if you can now boot your PC normally and without the BSOD error.
