How to Fix REGISTRY_ERROR in Windows

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

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• Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.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

2. 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.

3. 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.

2. 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.

3. 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.

4. Download Windows 10, 64-bit version.

5. Prepare an empty DVD or USB flash drive. Use Creation Media software then click the Create Installation Media for Another PC option.

6. 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.

7. 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.

When you receive Error 0x800704C8 when trying to move a file inside Windows 10 operation is stopped and it can not continue leaving you with the file in its original location without a copy. Several issues can be the cause of this type of behavior and error and after some digging and analyzing we are bringing you various solutions for this error and how to fix it.

Ownership issues

It turns out that not having ownership of fie can cause this error and prevent you from copying it. For some reason, Windows can assume that file is owned or used by another application or process and thus prevents you from making a copy since you do not have ownership of it. Resolving this particular issue will require you to install a third-party application that is tailored for this kind of task. After some talk and research, we found out that there is a freeware application that can solve this issue quite fastly. Unlocker is the name and the download link is here. Once downloaded, install it and run it. Once inside the application browse to the location where you need to change the ownership, click on it to select it, and click OK. Use the No Action drop drown menu to select Move, then click OK

Antivirus Issue

As with other file and application issues, this error could also be a product of antivirus marking it inaccessible to Windows and thus preventing copy or move operation on it. note: Do not turn off Windows defender since it was proven that it is not the cause of this kind of error, so if you are using only Windows defender you can skip this solution. How temporary turning off each security suite is different and it depends on the application itself we can not cover in detail the procedure here. Go to your security suite manufacturer's website and get information there or if you want, go directly to applications and features inside Windows and uninstall the software.

Visual Studio issue

• If the file you are trying to move is part of a Visual Studio project then the issue can be linked directly to Visual Studio itself, luckily the solution is quite easy. All you have to do it to exit Visual Studio and then run it with administrator privileges.
• In order to run Visual Studio with elevated privileges locate its executable file and right-click on it.
• Choose properties and go to the compatibility tab
• Inside compatibility tab check box that says run this program as an administrator

Corrupted system files

If the previous solutions have not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC

If you are trying to update your Windows 10 computer but are not able to do so since your computer is running low on storage then this obviously indicates that there is not enough disk space available on your drive where Windows 10 has been installed. As you know, when Windows 10 downloads the update packages, it extracts them in a separate folder which means that there should be enough space on that particular folder for the update to begin with. Windows do not really check systems for any adequate space requirements before it even initializes the update or upgrades and you only get to know about it right when the update process starts. On Windows 10 thin clients or the ones with embedded systems that have limited storage space, when Windows Update runs, the update initialization may fail because as pointed out, Windows does not check systems for adequate space requirements so you may have to do the work for them by making sure that your disk has enough space available. Here are some suggestions you can follow to resolve Windows 10 update issues on computers with low storage space.

Option 1 – Delete the files from the Download folder

Since you are going to delete everything manually, you need to create a backup for all your important files which you may have placed in the Download folder. After you create backup copies of important files, delete the files from this folder or you could simply tap the Shift + Del keys to remove the files permanently after you selected them all.

Option 2 – Change the Windows Update Folder location

You might have to change the Windows Update folder location where Windows download all the files need to update the operating system if you cannot really create some space on your primary driver. So all you have to do is set the drive with enough space available for the update to be completed.

Option 3 – Uninstall apps and programs you no longer use

In some cases, apps and programs take up a lot of space on your drive. So if there are programs or apps that you no longer use, you can uninstall them to save storage space. To do so, follow these steps:

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the apps and programs that you no longer use and right-click on each one of them and click on Uninstall.

Option 4 – Move files to another drive

This is another thing you can try. You can move files, especially the ones with large sizes, to another drive to make up space on your drive. After that, install the updates once again.

Option 5 – Reduce on-drive files from Cloud services

If you are using tons of cloud backup services such as OneDrive and Dropbox, you might want to consider reducing the number of files you have on those cloud backup services. You can do what you’ve done on option number three and have those files moved to another drive to free up storage space.

Option 6 – Empty the contents in Recycle Bin

As you know, the files that are deleted from your computer goes to the Recycle Bin first. So if you have not emptied Recycle Bin for a long time now, the files you delete are still actually taking up space on your drive. Thus, you need to empty the contents in the Recycle Bin to save storage space.

Option 7 – Clean up temporary files

You can use the Windows 10 Storage Sense feature which can clean all the temporary files from your computer. To use Storage Sense, follow the steps below.

• 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.
• Now make sure that the Storage Sense feature is turned On then go 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
• 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.

There are several possible reasons why this error pops up. It could be due to a recent Windows 10 update you’ve installed, or it could be due to a corrupted or outdated audio driver, and so on. There are several potential solutions to this error. You can try running the built-in Audio Playing troubleshooter or update or uninstall the Audio driver. You could also try to update the Intel Smart Sound Technology Audio Control driver, as well as contact support for your laptop or computer. For more details, refer to each one of the provided options below.

Option 1 – Try to run the Playing Audio Troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to update the Audio driver

If the error has something to do with software, chances are it might be related to the audio driver – it could be that the newest version of your Windows 10 does not work well with the old version of the driver. This is why you have to update your audio driver to the newest available version.

• Tap the Win + R keys to open the Run dialog box and then type in MSC and tap Enter or click OK to open the Device Manager.
• Expand the section of the Sound, video, and Game Controllers.
• And then from the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the driver.

Note: If updating the Audio driver didn’t work, you can go to the website of your PC manufacturer and look for the support section where you can download the drivers for your computer. You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 3 – Try removing and reinstalling the sound card

If option 1 didn’t work, you can also try to remove and reinstall the sound card of your computer to fix the high-pitched sound coming from your computer’s speakers.

• To get started, tap on the Windows key + R to pull up the Run box.
• Next, type in “MSC” in the box to open the Device Manager.

Having an eMail in today's modern world is no longer a privilege or being geeky, it has surely become a necessity. From Facebook to LinkedIn or Steam many services today require you to have an account in order to use them, and in order to create an account, you need working eMail. That being said many people today have several eMail accounts, one for social media, one for work, maybe even one for very close friends and family. How creating eMail today is completely free we might end up with several eMail accounts. eMail clients have also evolved much since their first days and became more than just applications for receiving eMails, today they can take various different tasks having additional features built into them like calendar, batch eMail processing, etc. Taking all of said into account I am presenting to you within my personal opinion some of the best eMail clients starting with free ones.

Best free eMail clients

Google Gmail

https://gmail.com It would be very difficult to even start a free eMail list without mentioning Google's Gmail. Introduced all the way back in 2004 as an invite-only service it became over time the most popular email platform largely due to the fact Google is offering free eMail accounts. There are a lot of good things to be said about Gmail itself, most of the area is clutter-free and the largest space is reserved for eMail itself letting users focus on what is important. WEB client itself means that you do not need to have any application installed on your device, altho via Google chrome, you can use Gmail offline offering you flexibility if needed. The ability to connect and manage other accounts like Outlook, Yahoo, etc is just making Gmail even more attractive, and the snooze feature is a really neat little detail that will pause eMail notifications if you need to focus on other things. Lack of organizing messages into folders is a little confusing since Gmail offers its own unique label system but sometimes I need to have old reliable save eMail to folder. All in all, Gmail is a great service and it offers a great eMail on the go experience.

Mail eMail client

https://www.microsoft.com/en-us/p/mail-and-calendar/ Free Windows eMail client simply called Mail is what was once outlook express. Mail itself has the ability to work with other popular accounts like Google Gmail account, Yahoo, iCloud etc. How it comes with Windows OS and it integrates very well with Microsoft Calendar, this eMail client is for many the first choice. On the negative side, I might say this is a strip-down version of Outlook which is paid solution so some features are missing if we would compare the two. Overall, a simple and nice eMail client worth your time, especially if you are on the Windows platform.

Mozilla Thunderbird

https://www.thunderbird.net Great eMail client matching in functions against paid and premium solutions of big tech companies. Fueled with plenty of customization options and reskinning ones this eMail client offers a lot for its free price tag. It is also fueled by Mozilla community focusing on privacy and security. It can work with any mail service and it is lightweight with a clean look, altho the look itself can be heavily customized. The bad side is that client itself relies on email services to provide cloud-based emails, so if you are receiving your email via a service that does not have a cloud-based service in itself all of your received emails will be locked to the computer where you have received them. Also customizing it can be sometimes a little too technical for the average computer user. All in all, Thunderbird is one great eMail client and it would be a shame not to use it because of its technical side, if you need a reliable and secure eMail client on a single machine, look no further than Thunderbird.

Paid eMail clients

Microsoft Outlook

https://www.microsoft.com/en-us/microsoft-365/ Outlook comes as a part of the Microsoft Office suite and as one of the oldest eMail clients, it is still widely popular and adopted through many users and businesses. It has tight integration with all Microsoft services and full integration with Calendar making it one of the if not the best eMail client out there. Outlook also has a free online service completely free for personal use as well. The downside is that you can not get it as a separate product if you want a business version other than as a part of the Office suite. The final verdict would be that this is perhaps the best eMail client out but the big downside is that there is no desktop version outside the Office suite.

eM Client

https://www.emclient.com/ eM Client offers a wide array of features, including a calendar, contacts, and chat. Support is provided for all the major email services including Gmail, Yahoo, iCloud, and Outlook.com. The latest version also offers PGP encryption, live backup, basic image editing capabilities, and auto-replies for Gmail. Its automatic system makes it very easy to get emails from other services since there is no manual setting, all that is needed is to type in your email and eM Client will do everything else automatically. A one-time purchase is not pricy and it could offer some features that some free clients are missing. Go check it out with a free trial and see if it is for you.

Mailbird

https://www.getmailbird.com This eMail client's main focus is the simplicity of use with visual appeal while tackling multiple eMail accounts. It has many built-in apps along with a customizable interface. Unlike some more Microsoft-centric email clients, Mailbird Business supports a diverse range of integrated apps, including WhatsApp, Google Docs, Google Calendar, Facebook, Twitter, Dropbox, and Slack, all making for a better-streamlined workflow. The downside of this client is the yearly subscription plan. I think people, in general, want to get away from software subscription plans so I will include this as a downside but bear in mind it is downside just in terms of a business plan not in the client itself.

Inky

https://www.inky.com/ Inky is eMail client if you are looking for security. It uses AI along with machine learning in order to block all types of phishing attacks that can get through to other clients. The proprietary machine learning technology can literally read an email to determine if it has phishing content, and then is able to quarantine the email or deliver it with the malicious links disabled. It also takes things a step further and offers an analytics dashboard, which allows an administrator to see patterns of attacks based on dates, or targeted users. The downside is that client itself is so much focused on security that sometimes some nonsecurity features get overlooked and provide a poor experience but if you need a good and greatly secured eMail client Inky is one to check out.

PC Optimizer Pro is a PC optimizer utility developed by Xportsoft Technologies. It is classified as a potentially unwanted program, due to its aggressive scan and registration reminders, and that it is often distributed bundled with other programs in a manner that leads many users to not know how it got on their computer. While not inherently malicious, PC Optimizer Pro adds numerous registry keys, startup entries and while running consumes a relatively high amount of system resources, especially during its scans. The software installs from a .exe file that is around 5.20 MB or 5.453.240 Bytes (depending on the version). As of the publication of these videos, the current version of PC Optimizer Pro was detected as malicious or potentially unwanted by at least 21 AntiViruses.

About Potentially Unwanted Applications

If you have ever installed freeware or shareware, chances are high that your computer can get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has other hidden goals. These kinds of programs are almost always bundled up with free software which you download from the net or are also bundled within the custom installers on many download sites. PUPs did not really constitute pure “malware” in the strict sense of the term. Just like malicious software, PUPs cause problems when downloaded and installed on your PC, but what makes a PUP different is that you give consent to download it – although the truth is vastly different – the software installation package actually tricks you into accepting the installation. Irrespective of whether it is regarded as malware or not, PUPs are nearly always harmful to the user as they might bring on adware, spyware, keystroke logging, and also other bad crapware features on your computer.

What do PUPs do on your computer, exactly?

Potentially Unwanted Programs come in many forms and varieties, but in most instances, these are adware programs that show annoying pop-up adverts and advertisements on websites you check out. The PUPs also get installed into your computer in the form of web browser add-ons and toolbars. Not only they needlessly take up space on your computer screen, but toolbars may also manipulate search engine results, watch your web browsing activities, decrease your web browser’s efficiency, and decelerate your internet connection to a crawl. Potentially Unwanted Programs at times act quite similarly to viruses or spyware. Some PUPs include keyloggers, dialers, along with other software to gather your private details that may result in identity theft. These are programs that don’t do anything good for you; in addition to taking over space on your hard drive, they also slow down your computer, often modify settings without your approval, the list of bothersome features goes on.

Ways to avoid PUPs

• Always study the EULA and privacy statement. Don’t agree until you know precisely what you are acknowledging. • Choose the “custom” install whenever installing a software program. In particular, look closely at those small boxes that have been checked as default, where you may ‘agree’ to receive promotions or install software bundlers. • Use good antivirus software, like Safebytes Anti-Malware that offers real-time protection against PUPs. • Avoid adding a freeware program you do not use. Turn off or remove toolbars and web browser extensions you don’t really need. • Always download software from reliable sources like official sites as opposed to untrustworthy sharing space. Avoid file-hosting sites where/when possible.

What you can do if Malware Prevents You From Downloading Or Installing Antivirus?

Practically all malware is bad, but certain types of malware do much more damage to your computer than others. Certain malware goes to great lengths to stop you from downloading or installing anything on your personal computer, particularly antivirus applications. If you are reading this right now, you have probably recognized that a malware infection is the real cause of your blocked web connectivity. So what to do if you need to install an antivirus program like Safebytes? There are a few steps you can take to circumvent this problem.

Install in Safe Mode

The Windows OS has a special mode known as “Safe Mode” in which just the bare minimum required programs and services are loaded. In the event the malware is blocking the internet connection and affecting the computer, running it in Safe Mode will let you download antivirus and run a diagnostic scan while limiting possible damage. To start the computer into Safe Mode, press the “F8” key on your keyboard right before the Windows boot screen comes up; Or right after normal Windows boot up, run MSConfig, look over “Safe Boot” under Boot tab, and click Apply. After you reboot into Safe Mode with Networking, you can download, install, and update anti-malware software from there. Right after installation, run the malware scanner to remove standard infections.

Switch to an alternate browser

Some malware may target vulnerabilities of a specific browser that block the downloading process. If you seem to have malware attached to Internet Explorer, then switch over to an alternate web browser with built-in safety features, such as Firefox or Chrome, to download your favorite antivirus program – Safebytes.

Install and run anti-virus from the USB drive

Another solution is to create a portable anti-malware program on your USB stick. Adopt these measures to employ a thumb drive to clean your infected computer system. 1) Download Safebytes Anti-Malware or MS Windows Defender Offline onto a clean PC. 2) Plug the Thumb drive into the clean computer. 3) Run the setup program by double-clicking the executable file of the downloaded software, with a .exe file format. 4) Choose the flash drive as the location for saving the file. Do as instructed on the screen to complete the installation process. 5) Now, plug the pen drive into the corrupted computer. 6) Double-click the anti-malware software EXE file on the USB flash drive. 7) Press the “Scan” button to run a full system scan and remove viruses automatically.
