How to Fix Windows 10 Upgrade Compare Exchange128 Error Message

Compare Exchange128 error – What is it

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.

Solution

Restoro box imageError Causes

The CompareExchange128 error normally occurs due to two possible reasons:

  • CPU lacks CMPXCHG16b Instruction
  • Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.

Further Information and Manual Repair

One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.

NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.

Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b

Method 1 – Update your BIOS

This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:

  1. Determine first the current BIOS you have on your computer. Open System Information Windows app and type msinfo32 in the search bar. The BIOS version will appear under the processor speed. Record it somewhere.
  1. Go to the support page of your motherboard’s manufacturer. Find if there’s any update on the BIOS that you’re currently using. If you find one, download the BIOS update file available. Make sure that you’re looking into the right model and you download all the necessary documentation. Otherwise, the BIOS update might not work.
  1. Update your BIOS. Most BIOS update steps are straightforward. Just make sure to follow the steps provided.

Method 2 – Install Windows 10 32-bit version

If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:

  1. Download and install the 32-bit version of Windows you currently have. If you have a Windows 7 64-bit version, get the 32-bit version of Windows 7. The same goes for Windows 8.1. When you do this, you might want to back up your files first. Remember that installing the 32-bit version works like other installations, and could delete some of your files.
  1. After installing the 32-bit version, go to Updates and install all the necessary updates. This includes upgrading to Windows 10 if you’re asked to.
  1. When you installed the Windows 10 upgrade, you’ll now have the Windows 10, 32-bit version installed. This will be the version activated on Microsoft servers. Despite this, the activated version stored is only applicable to your computer’s hardware, not the version of Windows 10.
  1. Download Windows 10, 64-bit version.
  1. Prepare an empty DVD or USB flash drive. Use Creation Media software then click the Create Installation Media for Another PC option.
  1. Install the 64-bit Windows 10 version you downloaded from Step 4. Make sure not to put anything when you’re asked to input the serial number.
  1. Once the installation is complete, you’ll have the 64-bit version of Windows 10.

Method 3 – Buy a new processor/motherboard

If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.

Method 4 – Download an automated tool

If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.

How to know if you have keylogger in Windows
Hello and welcome everyone, today we will be talking about dreaded keyloggers, why they are dangerous, and how to know if you might have one in your system. Keylogger is a malicious application placed in your system and hidden with only one goal in mind, to get information about what are you typing and by that means for a person who infected you to get information about your credit card information or other sensitive data. They can be introduced into your systems in various ways and often can not be detected easily. Modern antivirus applications have ways of detecting them and removing but this tutorial aims to teach you how to spot them all by yourself since new keyloggers are produced daily and sometimes relying on antivirus alone is not enough. Unlike viruses and trojans, keyloggers are not heavy on system resources and you will not feel slow down on your computer if you have one which makes them harder to sport with regular work. Some of them can be even tracking you on the website and not even be physically present on your computer. Generally, we could categorize keylogger into 4 categories:
  1. Web browser-based keylogger. Some websites would have CSS scripts, input web forms, or so-called man in the middle keylogger. Lucky for us even Windows defenders with the latest update can detect this type of keylogger and successfully deal with it and how keylogger itself is not present on our system we are safe.
  2. General spyware keylogger. This keylogger is present in your system, usually, it infected it via email attachment, social media download, torrent download, some malicious so-called fixer application, etc. Most antivirus applications and windows defenders can detect these types as well and remove them successfully.
  3. Kernel-level keylogger. This keylogger is a more dangerous type they tend to operate underneath Windows as a rootkit and can go undetected by antivirus and windows defenders.
  4. Hypervisor-based keylogger. This is the most dangerous keylogger, they use virtualization techniques to hide and mask themselves as a replica of the operating system and they scan all keystrokes by the user. These are very rare keyloggers but they do exist.
If you suspect that you have a keylogger or just want to check your system for precaution reasons follow these tips and guides and luckily you will solve your issue in no time and your data will be safe.
  1. Use Task Manager to find suspicious entries.

    Task manager is a great application implemented in Windows that is constantly monitoring and showing all services, applications, and processes currently running on your system and thus a great tool to monitor your system if you know how to use it. First, open task manager by pressing CTRL + SHIFT + ESC Then take a good look into it, try to find suspicious names, probably duplicate of running application, something like Windows logon application, or keylog or anything similar which seems out of ordinary. If you manage to find a suspicious running application right-click on it and close it. Also while you are in task manager jump into the startup tab and check to see are there some unusual applications starting with your Windows, if you find anything, disable it right away. This is the most simple and quickest way to get some information right away if you suspect to have some simpler keylogger in your system.
  2. Use the command prompt to monitor your network.

    In order to check connections to your computer and find potential suspicious ones start the command prompt in administrator mode, press ⊞ Win + X, and choose command prompt (administrator). type in netstat -b and press ENTER. All website and application connections to your computer are now visible. ignore svchost, edge browser, windows store, etc ad check the IP of the remaining ones using the internet.
  3. Use keystroke encryption.

    Install encrypting software and even if you have a keylogger, the application will encrypt each stroke and all that attacker will get is gibberish
Please remember to always download files from trusted sources, do not open unknown emails, and do not share your information publicly. Take common protection steps in order to protect yourself in the digital world.

FreeMaps Removal Tutorial

FreeMaps is a google chrome extension by Mindspark powered by Ask or MyWay. This extension offers users a quick and easy way to find the routes or locations that they desire. While all of this may seem appealing, this extension was classified as a Browser Hijacker by many anti-virus applications and was marked for removal.

When installed FreeMaps will change your home page, new tab and default search engine to MyWay.com, it will monitor your browsing activity and send it back to Mindspark ad servers. This data is later used/sold to better display targeted ads depending on your search queries.

While browsing the internet with this extension active you will see additional pop-up ads, sponsored links, and injected ads displaying throughout your browsing sessions, and even injected into websites that should be ad-free. Due to poor code optimization, these ads can sometimes cover a part of the page, making it unreadable or inaccessible.

About Browser Hijackers

Browser hijacking is a form of unwanted software, commonly a browser add-on or extension, which then causes modifications in the web browser’s settings. Browser hijackers are capable of doing more than simply changing home pages. These are typically used to force hits to a specific site, manipulating web traffic to earn ad revenue. It could seem naive, but most of such websites aren’t legitimate and could present a major threat to your online safety. As soon as the malware attacks your laptop or computer, it begins to mess things up a whole that slows your computer down to a crawl. In the worse case, you will be forced to tackle serious malware threats too.

How you can know whether the browser is hijacked?

Signs that your web browser is hi-jacked include: your browser’s homepage is suddenly different; bookmark and the new tab are likewise modified; default web engine is modified; find new toolbars which you didn’t add; unstoppable flurries of popup adverts show up on your computer screen; your browser has instability issues or exhibits frequent errors; you cannot visit specific websites such as home pages of anti-malware software.

Exactly how browser hijacker finds its way onto your computer

A browser hijacker could be installed on your PC if you check out an infected website, click an e-mail attachment, or download something from a file-sharing website. They can also be deployed via the installation of a web browser toolbar, extension, or add-on. Some browser hijackers spread in user’s computer systems by using a deceptive software distribution method known as “bundling” (usually through freeware and shareware). Typical examples of browser hijackers include Conduit, CoolWebSearch, OneWebSearch, Coupon Server, RocketTab, Searchult.com, Snap.do, and Delta Search. Browser hijackers can record user keystrokes to gather potentially invaluable information that leads to privacy issues, cause instability on systems, drastically disrupt user’s browsing experience, and eventually slow down the system to a point where it becomes unusable.

Tips on how to remove browser hijackers

Some types of browser hijackers can be removed from your PC by deleting malicious software applications or any other recently installed shareware. Having said that, many hijackers are very tenacious and require specialized tools to eliminate them. You should think of carrying out manual repairs only if you are a tech-savvy person since there are dangers associated with messing around with the computer registry and HOSTS file. Professionals always suggest users to remove any malicious software including browser hijacker with an automatic malware removal tool, which is better, safer and faster than the manual removal procedure. One of the best tools for repairing browser hijacker malware is SafeBytes Anti-Malware. It will help you remove any pre-existing malicious software in your pc and provides you real-time monitoring and protection against the latest threats.

How To Install Safebytes Anti-Malware On An Infected Computer

All malware is inherently harmful, but certain kinds of malware do a lot more damage to your computer or laptop than others.

How to Fix win32kfull.sys BSOD Error in Windows 10
The win32kfull.sys file is one of the kernel-mode device drivers in your Windows 10 operating system. In case you don’t know, there are two kinds of device drivers – the first ones are the normal drivers that communicate between your hardware and the operating system while the second ones are the kernel-mode drivers. The latter is necessary for booting your OS. And there are times when you encounter the win32kfull.sys error while booting your PC. Here’s the full context of the win32kfull.sys error:
“SYSTEM_SERVICE_EXCEPTION (win32kbase.sys) APC_INDEX_MIXMATCH PAGE_FAULT_IN_NONPAGED_AREA”
This error could be caused by corrupted or outdated drivers with incomplete files or it could be caused by some driver or software installed on your computer. To fix this error, here are some troubleshooting options you need to check out.

Option 1 – Try updating all the Drivers

As pointed out, the win32kfull.sys error can be due to outdated or corrupted drivers that are not compatible with your hardware. These drivers include but are not limited to display, network, sound, hard drive, and more. If you are not able to access the internet, you can just manually download the update using another PC. To update your drivers, here’s what you need to do:
  • Tap the Win + R keys to launch Run.
  • Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
  • Restart your PC.
Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it. After that, you could also check if there’s a new update of the game you’re getting the issue of the black bar.

Option 2 – Identify and uninstall problematic programs by putting your PC in a Clean Boot State

One of the main causes of BSOD errors like win32kfull.sys is a problematic program that could clash with your existing operating system as well as computer architecture. There are tons of programs that are either incompatible or conflict with the existing drivers or software in your system. To identify such programs, you need to put your PC in a Clean Boot state. How? Follow these steps:
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:
  • From the “Start” menu, go to System Configuration.
  • After that, switch to the General tab and click the option for “Normal Startup”.
  • Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
  • Then find and click “Enable all” and if prompted, you have to confirm.
  • Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
  • Restart your PC when prompted.
Once you have identified the program causing the problem, uninstall it right away from your Control Panel.

Option 3 – Perform an SFC scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the win32kfull.sys error. 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.

Attempt was made to reference a token
If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc. Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.

Option 1 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.
  • Open Command Prompt as admin from the WinX menu.
  • Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
    • exe /[DLL file]
    • exe [DLL file]
Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.
  • After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

  • First, you need to get the new DLL file from another computer with preferably the same file version number.
  • After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
    • x86: This PC > C:/Windows/System32
    • x64: This PC > C:/Windows/SysWOW64
  • Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
  • Now type the “regsvr32 ntdll.dll” command and hit Enter.
  • Restart your PC and check if the error is now fixed.

Option 3 – Perform a System File Checker scan

The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. 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.

Option 4 – Try reverting back to the previous build of Windows

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.
