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  • Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.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

No usable free extent could be found
One of the most useful and efficient command-line disk management tools is the DISKPART utility. It can be used to manage, delete or create new hard drive partitions. However, despite its efficiency, there are still times it could face some errors like the “No usable free extent could be found”. You can encounter this error when you create a partition. This error could be due to insufficient disk space which is why it is not able to carry out the operation. It is also possible that the disk is not recognized by the system. And since there are only four recognized primary partitions, when you try creating a fifth one, you will get this error. In addition, this error could also occur if the disk has been partitioned using the MBR disk partitioning format. To fix the “No usable free extent could be found” error, here are some suggestions you can follow.

Option 1 – Free up disk space using Storage Sense

The error could be caused by insufficient disk space in your computer and so you need to free up disk space using Storage Sense to fix the problem.
  • Open Setting > System > Storage from the WinX Menu.
  • From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
  • Next, find a link that says “Free Up Space” and click it to open.
  • After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
    • Windows Upgrade Log Files
    • The system created Windows Error Reporting Files
    • Thumbnails
    • Temporary Internet Files
    • Previous Windows Installation Files
    • Delivery Optimisation Files
    • DirectX Shader Cache
  • Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
  • Now go to the “Free Up Space Now” section and click the Clear Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix Error 1310.
Note: You can also run the Disk Cleanup tool to free up disk space.

Option 2 – Try to run DISKPART in Command Prompt with administrator permissions

The next thing you can do to resolve the error is to run the DISKPART utility with admin privileges.
  • In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
  • Once you found it, right-click on it and select the “Run as administrator” option.
  • After that, try to execute the Diskpart operation once again. Note that you also have to specify different size & offset values for the partitioning and then see if you still encounter the same error.

Option 3 – Try to execute the DISKPART clean command

The next thing you can try is to execute the clean command in DISKPART to fix any issues in the disk.
  • Open Command Prompt with admin privileges.
  • Then execute this command: diskpart
  • The command you entered will initiate the DISKPART utility. Now execute this second command to view all the disk connects or all the partitions on those disks formed: list disk
  • After that, you need to select one command depending on the list command you executed and then execute this third command: select disk #
  • The third command you just executed will select the disk or partition you want to select. Now execute this fourth command: clean
  • The command you entered will remove all the volumes or partitions formatting the disk in focus.
  • Once it’s done, try to carry out the DISKPART operation you were trying to execute.

Option 4 – Try to update the USB drivers

Outdated USB drivers can also be the reason why you’re getting the error. Thus, you must update them from time to time. You can install the latest version of the USB driver for your system. But you need to check the manufacturer’s website or guidelines to update the driver according to your system. If it happens that the drivers might not be compatible with the version of the system your laptop is using which is unlikely, you can run the driver software in Compatibility Mode in that kind of situation. To update your USB drivers, follow these steps:
  • 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, look for the USB Serial Bus controllers from the list of device drivers 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”. 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.

Option 5 – Run the Hardware and Devices troubleshooter or the USB troubleshooter

You can find the Hardware and Devices troubleshooter under the Troubleshooters section of the Windows Settings panel on your Windows 10 PC. You can use this troubleshooter to fix common hardware and external device-related issues without exerting too much effort. If you don’t know where to find it, follow these steps:
  • Tap the Win + I keys to open the Windows Settings.
  • Next, navigate to Update & Security > Troubleshoot.
  • You should see the option for Hardware and Devices on your right-hand side where you can also find the “Rub the troubleshooter” button – click on it to get started.
  • Follow the next on-screen instructions to fix the basic issues of common hardware and external device.
Note: If you want to, you can also use the USB Troubleshooter to fix the problem just go back to the Troubleshoot page where you can find it.

Fix Hello Errors 0x801c004d or 0x80070490
As you know, Windows Hello offers you quick access to computers since you can log in to your Windows devices three times faster compared to passwords with the help of the camera via Face recognition and fingerprint reader. This way, Windows Hello will recognize you right away. However, there are also times when you might encounter some problems when using Windows Hello. For one, if you are trying to add the PIN method to Windows Hello on your Windows 10 computer but you suddenly encountered an error code of 0x801c004d or if you are trying to use your existing pin and you encounter an error code of 0x80070490 along with an error message that says, “Not recognized”, then read on as this post will guide you on how you can fix both of these errors. Here is the complete content for both errors:
  • 0x801c004d – Unable to enroll a device to use a PIN for login”
  • 0x80070490 - Not recognized, Pin and fingerprint are no longer options for signing in”
If you got any of these two errors, there are several potential fixes you can check out to resolve them. You can try to check for any Windows Updates or create the PIN again or check the CNG Key Isolation Service. You could also try to reset the TPM or create a new User Account. For more information, follow the instructions provided below.

Option 1 – Try checking for any available Windows Updates

The first thing you can do is to check for any available Windows Updates. It is possible that your computer may be outdated and is the reason why you’re having troubles with Windows Hello. To check for Windows Updates, just go to Settings and from there, head over to the Update and Security section and click on Windows Updates located on the left pane, and then click on the Check for Updates option. Wait until the process of checking updates is completed and if it finds new updates, install it. After you install the new Windows Updates, check if you can now add the PIN on Windows Hello or not.

Option 2 – Try creating the PIN again

The next thing you can do is to create the PIN again by signing out and signing in again and then try creating the PIN once more. If this does not work, you can try restarting your computer and creating the PIN again. You could also try removing the PIN and then change it.
  • Remove the PIN by going to Settings > Accounts > Sign-in options.
  • From there, go to the PIN section and click on the Remove button.
  • You will be asked to verify your account to proceed in removing the PIN, enter your credentials.
  • Restart your computer and then set up a new PIN.
  • Once you’re done, restart your computer and check if the error is gone now.

Option 3 – Try checking the CNG Key Isolation Service

The CNG Key Isolation Service is the one that stores and uses long-lived keys in a secure process complying with the common criteria requirements and it is possible that the error could be related to this service. This service is hosted in the LSA processes and provides key process isolation to private keys and associated cryptographic operations as required by the common criteria. Thus, you need to check this service to see if it’s the one that’s causing the error.
  • Tap the Win + R keys to open the Run dialog box and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
  • Next, locate the “CNG Key Isolation Service” and once you find it, double click on it to open its Properties box.
  • After opening its Properties, check its Startup type and select Manual. This is the default setting and if it is Disabled, then it’s no wonder why you’re getting errors with Windows Hello, thus, you need to enable it.
  • Once done, restart your computer and check if you can now add the PIN to Windows Hello. If you still get the error, then you might want to try setting the CNG Key Isolation Service from Manual to Automatic and then click on the Start button and see if it fixes the error or not.

Option 4 – Try to reset the Trusted Platform Module or TPM

You might also want to try resetting the Trusted Platform Module or TPM to fix the error. You can do this by opening Windows PowerShell and then executing the “Clear-Tpm” command. After that, check if the error is now resolved.

Option 5 – Try to create a new User Account

You could also try to create a new User Account on your Windows 10 computer to fix the Windows Hello error. Once you have created a new local user or administrator account in Windows 10, check if you are now able to add the PIN from this newly created user account.

Fix Windows 0x8007002C – 0x400D Error
In Installing or upgrading your Windows 10, there really is no guarantee that everything will go smoothly as there are times you encounter errors like the “ We couldn’t install Windows 10, 0x8007002C - 0x400D ” error message among other Windows update/upgrade errors. When you encounter this particular error message you will the following message on your screen:
 “We’ve set your PC back to the way it was right before you started installing Windows 10. 0x8007002C-0x400D The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation”
This kind of Windows upgrade error indicates that some of the files needed for the installation are locked out for some reason and that Windows was not able to migrate them to a new version. It could be that your computer does not have sufficient space for those files. Thus, no matter how many times you try to upgrade your computer, you always end up going back to the previous version of Windows. To fix the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error, here are some suggestions that might help:

Option 1 – Disable your antivirus program

There are times when the antivirus program installed in your computer blocks file access and even disk access. Thus, disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 2 – Perform a Disk Cleanup to free up disk space

Chances are, some unnecessary files in your computer might be interrupting the installation process which explains why you’re getting the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error instead so you need to perform a Disk Cleanup in order to fix the problem.
  • In the Cortana Search box, type “disk cleanup” and click on the related search result.
  • Then select the disk you want to clean and click OK.
  • Wait for the process to be completed and then restart your PC and try to install the Windows upgrade again.

Option 3 – Get rid of any file protection software

The Windows setup migrates the folder from one version to another during the upgrade. However, if some of your folders, if not all, are protected using some file protection software, then Windows won’t succeed in moving the folder and you will encounter this Windows upgrade error instead. Thus, you need to unlock all those protected files or better yet uninstall the file protection software after you remove the locked files. After that, try installing the upgrade again.

Option 4 – Rename the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.
  • Open the WinX Menu.
  • From there, open Command Prompt as admin.
  • Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv net stop bits rename c:windowsSoftwareDistribution SoftwareDistribution.bak
  • After entering these commands, it will stop the Windows Update Service, the Background Intelligent Transfer Service, and rename the SoftwareDistribution folder.
  • Next, got to the C:\Windows\SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
  • Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.
net start wuauserv net start bits
Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Option 5 – Run the DISM tool

As mentioned, the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error might also be caused by corrupted files in the computer. Thus, you can try using the DISM tool to repair them. Running the DISM tool can repair the Windows System Image and Windows Component Store in Windows 10.
  • Open the Command Prompt as admin.
  • Then type in this command: DISM /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 6 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve this particular Windows upgrade error. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Option 7 – Try running Microsoft’s online troubleshooter

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors including the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error.

Fix Folder Redirection Failed in Windows
If you got an error message saying, “Folder Redirection Failed, Failed to build the list of regular subfolders, Access is Denied” after you configured a new Group Policy Object or GPO which redirects User folders to a new network share or when you click on Reset default location under the Windows File Explorer or Folder Options, then you’ve come to the right place as this post will show you how to resolve this kind of error on your Windows 10 computer. Follow the given options below carefully to fix the “Folder Redirection Failed” error.

Option 1 – Take Ownership of the folder

If you are not able to access the folder could be one of the reasons why you’re getting the “Folder Redirection Failed” error and so you need to take ownership of the folder to resolve the problem. Before you proceed, make sure that your account is an admin account.
  • First, locate the concerned folder and right-click on it then select Properties.
  • Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
  • After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
  • Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
  • Now edit the permission to Full Control for “Everyone”.
  • Click OK to save the changes made and then exit.

Option 2 – Try to add Authenticated Users or Domain Computers

Make sure that the Folder Redirection group policy removal option is set to “Redirect the folder back to the user profile location when the policy is removed” when using the Folder Redirection. After that, you have to add Authenticated Users group with the “Read” permissions on the Group Policy Objects or GPOs. And if the Domain computers are part of the group of “Authenticated Users”. Note that by default, the “Authenticated Users” have these permissions on any new Group Policy Objects or GPOs. Once again, you have to add just “Read” permissions and not “Apply Group Policy” for “Authenticated Users”. Furthermore, to fix the “Failed to build the list of regular subfolders” errors, here are some options that could help.

Option a – Try to clear disk space

You might have to check if your disk is running out of space because if it is, then it will fail to create a list abruptly. And so you need to free up some disk space. You can either check on the files manually especially if you tend to keep your files at random places in your disk drive.

Option b – Find the Target route

You need to find the target route of the folder and then restore it if you are getting the “Failed to build the list of regular subdirectories” when you try to relocate the folder to the original location.

Option c – Try to change Ownership/Reset Defaults for all the User folders

If the “Failed to build the list of regular subdirectories” error pops up when you are trying to move a large number of files from one location to another, then you need to change the ownership of the folders as pointed out earlier.

Experiencing Error Code 36, We Have A Solution!

Error Code 36 – What is it?

This is a common Device Manager Error Code that users encounter. It is commonly found on all Windows 2000 and later versions of Windows operating systems. Error Code 36 is usually prompted by the following message:

Solution

driverfix boxError Causes

Error Code 36 occurs when there is a failure in IRQ translation due to your Windows operating system getting corrupted. This is caused due to a number of triggers, such as:

  • An excess of startup entries
  • Errors in registries
  • RAM or hardware failure
  • Excessive unnecessary installed programs
  • Malware or spyware

When programs are removed excessively, some programs are not removed completely and create problems in your computer’s registry.

Also, due to the presence of malware and spyware and other causes mentioned above, your computer registry builds up errors with the time that leads to slowing your PC, time lags, and even result in crashes and freezes.

Error Code 36 can cause internal and external components to malfunction or experience time lags such as DVD drive or printer and hence can severely affect your entire PC.

Further Information and Manual Repair

Error Code 36 is a severe PC error and any attempt at fixing the error must be approached with extreme caution for your PC to start functioning properly again. Here are two methods to fixing your PC.

Method 1 – Change IRQ reservation settings

Changing the IRQ reservation settings is the best way you can rely on to fix the error code. You can do this by changing the BIOS settings of your PC.

The BIOS stands for ‘Basic Input/Output System’ and is the program of your PC’s microprocessor that allows your PC to boot after you switch it on.

Caution needs to be exercised before changing the BIOS settings of your PC. This is because every PC’s BIOS version differs from another and any wrong attempt to change the settings may make matters worse.

It is therefore recommended to refer to hardware documentation that you received with your PC or motherboard and check for the model number and details of your PC’s motherboard.

Only after you have checked and confirmed all the details, should you use the specific BIOS settings required to configure your IRQ reservations?

Method 2 – Install DriverFIX

Error Code 36 isn’t an easy error to remove.

While changing the BIOS settings can work to restore your PC, it may create a whole lot of inconvenience for finding the time and effort to check the hardware documentation details and attempting to change the specific settings and especially, if your PC does not support the options to change IRQ reservations.

Given the high risks of fixing such an error, you can also install software that enables you to fix your slow PC at the click of a few buttons.

Programs such as DriverFIX can enable you to download and replace your outdated drivers with new updated ones without you having to look for them. It will detect which drivers to download based on your PC’s motherboard version from the program’s database and can get rid of error code 36.
