Fix Windows defender 0x800700AA Error

We have often talked about the security of your computer, we have been giving you tips and tried to explain how to best protect your computer from various attacks and malicious software. Today we will be talking about antivirus applications. Antivirus software has become the kind of a must-have in every computer in this day and age. When you think about it, our systems are connected to the internet most of the time if not always, and therefore kind placed in from the line of various cyber-attacks. Here antivirus software comes into focus, especially because it has evolved long from just a simple virus removal tool to full security suites. We will be going through the best of these applications in order to present both their good and bad sides and hope that we will help you in picking the right one for you. Remember, picking either one of the presented solutions is way better than not having one at all. The list is made from best down in our opinion so number one is highly recommended.

List of Best antivirus applications of 2021

1. BitDefender

   In our opinion the best overall security protection suite for this age and time. Bitdefender has cemented itself as number one a few years back and it holds that status even today. It has top-of-the-game virus protection, an incredible amount of features, safepay banking online protection and it is amazingly cheap. Its downside we could say is that it can be annoying sometimes, especially if you set it to maximum protection and paranoid mode. In this case, it will often ask what to do and how to behave leading to minor annoyances.

2. Norton antivirus

   Norton antivirus is well known to older computer users, this package has been around a long time and it is our pick for closest one to challenge top place because of its packed features. The number of features it has are really stunning and it comes also with great and maybe best-browsing protection of all candidates. It also has a backup tool bundled with it but the reason why it is in the second place is that it is taxing to the system and can have a real impact on computer performance. Great protection is important, but so it is working on it without slowdowns.

3. Kaspersky

   Another one of the old antivirus software on the list. Kaspersky Lab was once top tier antivirus software but it dropped down due to its high prices, later they have changed their pricing to be more in trend with other rival companies but many have switched to something else. Today it still packs one of the best antivirus engines with fast and configurable scans. It also has very impressive anti-ransomware features but sadly most of the things it just simply does for you leaving you to fully trust it since you cannot really configure much. It is not in step with new technologies and it is lacking some features like support for the Chrome browser that places it lower in our ranking.

4. Trend Micro antivirus

   The biggest sell point for this antivirus application is probably its ease of use and user-friendliness. It also packs a great antivirus engine and impressive anti-ransomware performance but sadly it comes with very limited configurability and somewhat lack of features comparing it with the top three entries. Never the less a very user-friendly application that you can configure without knowing any kind of tech talk, everything is laid out in simple English.

5. Avira

   Perhaps best known for its free version, Avira has a premium one that is well better worth than the free version. Strong suites of this software are mostly aimed at the internet with its great anti-phishing and web protection along with a low price for all of its features. Sadly in the domain of virus protection, there are some reports from independent websites that its antivirus engine is not so great, it will offer you moderate protection but not the best.

6. Webroot Secure Anywhere

   If you are on the lookout for software that has a great virus database and plenty of features but is also incredibly light weighted and fast then look no further, Webroot Secure Anywhere is an application for you, incredibly fast and incredibly small is a great solution for older machines. It keeps all of its databases up in the cloud and this feature among its great advantages is also its greatest disadvantage since if you are out of the internet you will not be able to have the latest virus definitions available to you making this tool very situational.

7. Avast

   Avast has many great protection features and it is very highly configurable. The firewall comes also in its premium edition and it offers great virus protection including a file shredder and awesome WI-FI inspector for an extra layer of security. This package would be higher on the list if it was not for its lack of WEB protection and its tool on the system resources.

8. Sophos home antivirus

   Lack of features and somewhat strange user interface are downsides of this software but on its positive side it has good antivirus engine and its user interface is very friendly. Where it shines though is in its price, for one affordable price you get protection for 10 devices making this option a great choice for anyone wanting to protect more devices or just use a single license for the whole family.

9. ESET antivirus

   Greatly configurable antivirus software with tons of options and very light on system resources makes ESET one of the best out there. Virus engine and database is also top tier but some testing labs have reported that protection offering is not really what it is advertised and if we talk about its strong suite of a great many options and configurations it is at the same moment its downside since it is not very friendly to novice and beginner users.

10. McAfee antivirus

    McAfee antivirus comes in its package with unlimited VPN service and if we take look at the top tier pricing plan it is a great investment. Sadly for its entry-level price, it covers only a single device and it was reported that it packs little outdated virus engine if we compare it with its rivals. Nevertheless, it still offers good virus protection and if you take into account the VPN that comes with it, it can find its users.

Conclusion

No matter which antivirus you choose you will not go wrong, after all any protection is way better than none.

During Windows 10 installation, you will see all the beautiful user interfaces, however, what’s more, important are the drivers, your processor, and free storage disk in order for the installation to be successfully completed. So if you are getting the CompareExchange128 error during the installation of Windows 10, this means that the CPU lacks a very important instruction known as “CMPXCHG16B”. Thus, if you don’t have CMPXCHG16B, then it will result in the CompareExchange128 error when you install Windows 10. In fact, CMPXCHG16B, PrefetchW as well as LAHF/SAHF is a criterion for you to be able to use Windows 10 64-bit version when upgrading from an earlier version of Windows. So what exactly is the CMPXCHG16B instruction? The CMPXCHG16B instruction is the one that performs an atomic compare-and-exchange on 16-byte values. This instruction can also be referred to as “CompareExchange128”. The atomic compare-and-exchange means that the CPU compares the contents of a memory location with a given value. So if the values are the same, it modifies the contents of that memory location to a new given value. Note that this kind of issue only happens to the 64-bit Windows 10 version and the only way to resolve it is by getting an update on the hardware level from the OEM. On the other hand, if nothing really works, it’s maybe time for you to get a new CPU but before you resort to that, in the meantime, you can try following the options given below to fix the CompareExchange128 error during the installation of Windows 10.

Option 1 – Try to update the BIOS and Chipset Drivers

One of the best things you can do to fix the CompareExchange128 error is by updating the BIOS and chipset drivers which is why you need to check if your OEM has an update available for your computer’s BIOS as well as the related chipset drivers. But before that, you need to first check the BIOS version. To do so, follow these steps:

• Type “msinfo32” in the search bar and hit Enter to open the System Information Tools.
• After opening the System Information Tools, check the BIOS version.
• Then take note of that BIOS version. You also need to use the BIOS utility that came with your computer and use it for the upgrade. Note that it is different for every computer and if you don’t have it, you can just go to the OEM website and see if there is an option to download it there.

Option 2 – Try to downgrade to the 32-bit Windows 10 version

If option 1 didn’t work as the BIOS update is not available, you can also try downgrading to the 32-bit version of Windows 10. Keep in mind that this will bring restrictions on the amount of RAM installed and other places but that won’t be a problem as you can still switch.

Option 3 – Try buying a new hardware

If none of the first two options didn’t work for some reason then maybe it’s time for you to purchase new hardware especially if your computer is way too old. In such cases, it’s better to buy new hardware or better yet, a new computer that can keep up for the next couple of years.

FLoC is Google’s alternative to third-party cookies and is based on machine learning. This will allow the browser, any browser, to anonymously study how users are browsing and then group them into ‘cohorts’. Following this, you will be served ads based on your cohort and not on your individual data. So, you are still going to be targeted with ads but in a more anonymous manner. Google claims that this will improve user privacy since this “federated learning” happens on the user’s device and artificial intelligence-based learning involves sharing lesser users than what happens with third-party cookies. If something like this gets widely adopted by ad companies and services, it should “protect users” from tracking methods that are more intrusive than third-party cookies, like browser fingerprinting.

Who is against it?

Privacy-focused browsers DuckDuckGo, Brave, and Vivaldi have all warned users against FLoC and have said that they are going to block it on their end. Brave says that Google FLoC has a design that does not respect the customer’s privacy and consent. It has been designed to provide browsing behavior and interest data with any website that users may interact with, and this process does not involve fully informed consent. Vivaldi, another popular Chromium-based web browser, has also made its stance clear regarding the status of FLoC. The company said in a Reddit thread that the FLoC experiment does not work in Vivaldi. It happens because for FLoC to work, some features need to be enabled under the hood, but Vivaldi does not provide those options. The company also added that it plans to stop the entire FLoC component from being a part of the browser, regardless of how Google may implement it. Considering that Brave and Vivaldi have been privacy-focused browsers since their beginnings, the decision to stay away from FLoC is not surprising.

Error Code 0xC004F00F – What is It?

Error Code 0xC004F00F can appear during the Windows 10 installation and activation process. It is a fairly straightforward error code that occurs when a product key is entered in that is unable to be used to complete the final activation of the new operating system. This error code is most commonly related to the installation of new pieces of hardware on a machine that was already running Windows 10 at a previous time.

Error Code 0xC004F00F can also appear on other versions of the Windows software, so if you are not specifically trying to install and activate Windows 10 when this message appears, you may want to contact a qualified Windows technician to help resolve your system error, as the error code has different causes and resolution methods on other versions of the Windows operating system.

Solution

Error Causes

In some cases, Error Code 0xC004F00F will show up if you are attempting to install Windows 10 on a computer in which the hard drive has been replaced or significantly altered. It can also appear when other major pieces of hardware, like the motherboard, have been changed out.  These pieces may be changed as part of an upgrade to new or better hardware or be changed due to the malfunction of the original pieces of equipment. Because it may appear to the Windows activation servers that you are attempting to use the same product code that you have used before to activate what appears to be a new machine (even if the machine is the same one, just with some new parts), you may see Error Code 0xC004F00F arise.

Error Code 0xC004F00F can also come up if you have installed Windows 10 on your machine in the past and have already used the product key that you are attempting to use again.

Further Information and Manual Repair

Error Code 0xC004F00F most commonly appears for users who have made major hardware or software changes done on their machine. Because this error specifically arises from the Windows activation servers believing that your computer is a new one, you’ll need to get in touch with the Windows support team in order to resolve the error. From their database, they will be able to confirm that you are not using a new computer and will be able to bypass the error, allowing you to complete the Windows 10 Activation process.

If you haven’t installed or replaced any of the hardware on the computer, but are still seeing Error Code 0xC004F00F arise during your Windows 10 installation, you will still need to get in touch with the Windows support team to bypass the error code.

Calling the Windows' Support Team

When you call into the Windows support team, you’ll want to specifically have a list of the following information readily available: Which pieces of hardware have been changed out on your computer prior to the installation and activation, what method you were using to install Windows 10, which version of Windows 10 that you were attempting to install, whether it was a single-use or multiple-use license, and basic details about your PC like its make, model, and age.  You may also want to have the product key that you were attempting to use when Error Code 0xC004F00F first appeared.

By having all of this information ready and on hand ahead of time, you’ll have a greater likelihood that your error will be able to be resolved quickly and efficiently, avoiding long periods spent on the phone with customer service. Make sure that you specifically mention that you are experiencing Error Code 0xC004F00F during the Windows 10 activation process when you call into the Windows support team so that you can be connected to a representative who is equipped to help you resolve this specific problem.

Getting a Qualified Technician

If you are not comfortable in working with the Windows support team or have not been able to successfully resolve Error Code 0xC004F00F even after getting in touch with customer support, contact a qualified technician who is familiar with the Windows 10 activation process and can walk you through the things that you will need to communicate to the Windows support team in order to have them bypass or resolve the error code.

This tool enables users to access quick solutions. It also scans for and corrects issues that may result in error codes or poor PC performance.

Error 0xc0000225 is the error that occurs on system startup, most times error just disappears all by itself but in some cases, it can be really persistent and can even cause you not to be able to enter the system that could be a really annoying thing, especially if there is some important task waiting to be finished. In this guide, we will present you with solutions for this error and how to solve it so you can get back to work as soon as possible.

Solution if you can not log into windows due to repeating error

If an error repeats itself constantly and you are unable to boot into Windows itself you will need to prepare Windows boot USB. You can download the Microsoft media creation tool here and then use it to create a bootable USB with Windows 10. Once the USB is done reboot your system and boot from USB. CHoose repair Windows instead of install and follow onscreen instructions.

Solution if you can log into Windows

If you can log into Windows bring up the command prompt in administrator mode and type in it SFC /SCANNOW followed by ENTER, wait for the whole operation to finish, and then reboot the system.

Recently, a number of users reported that they were not able to use the “Run as administrator” context menu option when they tried using it or opening a program with administrator privilege. If you are one of these users facing this problem, then you’ve come to the right place as this post will guide you in fixing this issue. At the time of writing, it isn’t clear what the cause of the issue is but there are potential fixes you can try to fix the problem. You can try turning on the User Account Control or clean up the Context Menu items change the Group Membership. On the other hand, you can also perform both SFC and DISM scans via Command Prompt or troubleshoot the problem in a clean boot state as it is possible that some third-party programs are the ones that are causing the problem. You could also run an anti-malware scan using Windows Defender or your antivirus program.

Option 1 – Try to turn on the User Account Control

When you open a program with administrator privilege, the User Account Control or UAC prompt will pop up asking you to confirm the permission. However, if you have disabled the User Account Control by mistake or some malware has disabled it, then it’s no wonder why the “Run as administrator” option is not working. Thus, you need to check if UAC is turned on or not. All you have to do is go to the User Account Control settings.

Option 2 – Try changing the Group Membership

• First, you need to sign in with your administrator account or ask your administrator to sign in for you. So if you only have a Standard User account, you have to add that account to the Administrators group.
• In the taskbar search box, type “netplwiz” and check the search results.
• From there, select your user account and click the Properties button.
• After that, go to the Group Membership tab and select Administrator.
• Now click on the Apply and OK buttons to save the changes made and then sign in to your computer again and see if the “Run as administrator” option is working or not.

Option 3 – Try to create a new Administrator User account

If you have a standard account, you can try creating a new account but this time, you create an administrator user account and then see if you can now use the Run as administrator option or not. Note that you have to sign in with your main account before you can create an admin account.

Option 4 – Run the DISM tool

You can run the DISM tool as well to help fix the problem with the “Run as administrator” option. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• 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 – Perform a System File Checker scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the problem with the “Run as administrator” option on your Windows 10 computer. 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.

• Once done, restart your computer.

Option 6 – Put your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing you from using the “Run as administrator” option and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try to use the Run as administrator 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” check box 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” check box.
• 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, try to check if the error is now fixed and that you can now view the Properties.

Option 7 – Try scanning your computer using Windows Defender

As mentioned, if your computer was recently infected with some malware, it is possible that the malware changed the User Account Control settings which is why you’re not able to use the Run as administrator option. Thus, you need to scan your computer using Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

BIOS is software that is running in a chip located on your motherboard, you can enter BIOS usually by hitting DEL once the computer is turned ON but this sometimes varies and it depends solely on the motherboard manufacturer. Inside BIOS you can configure your computer components and set up some other important things including passwords for BIOS itself or for the entire system. Password itself is meant to protect access to BIOS from other non-technical users or to prevent access to the system from other people if for example computer is in one household and you would like to be the only one having access to it. However, passwords can be forgotten, and sometimes you can even purchase a second-hand computer with a password on it. In this guide, we will lead you through ways on how to remove your BIOS password so you can regain access to your BIOS settings.

1. Use Manufacturers master password

   Most motherboard manufacturers have built-in a couple of master passwords for BIOS access. If your motherboard has one you can easily find it on the manufacturer's website. Use the master password and remove other passwords inside BIOS, save and exit.

2. Remove CMOS battery

   If you could not find the manufacturer's master password or your motherboard model does not have one remove the CMOS battery to reset BIOS. Note that this method will reset the whole BIOS not only the password. Open on side of your computer casing and locate the round battery on it, do not worry, there is only one battery so you can not make mistake. Remove the battery and leave it outside for around 20 to 30 minutes then place it back as it was, CMOS is reset now and you can access BIOS.

3. Reset BIOS via jumper

   If you want to remove only the password and do not touch other BIOS setting you can locate the BIOS password reset jumper. How the location of this jumper and position is different from the motherboard to motherboard we can not cover them all here and it is advisable to read the manual or find information on the official manufacturer's website.
