Fix ATTEMPTED_WRITE_TO_READONLY_MEMORY

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.

Recently, a number of users reported an error while trying to update their computers. This particular Windows Update error has an error code of 0x80073701. If you are one of the users who encounter this error, then read on as this post will guide you on how exactly you can fix it. Here’s the exact context of the error:

“Updates failed. There were problems installing some updates, but we’ll try again later. 2019-07 Cumulative Update for Windows 10 Version 1903 for x86-based Systems (KB4507453) – Error 0x80073701”

The Windows Update Error 0x80073701 also comes with a code “ERROR_SXS_ASSEMBLY_MISSING” which indicates that some system files are missing on your computer that caused the update installation failure error. Although this Windows Update error does not cause any severe issues, it is still being reported in the section of Windows Update where it is marked as “Update failed”. There are several potential solutions you can check out to resolve this error. You can try to run the DISM tool or the SFC or System File Checker scan. You could also try to run the Windows Update troubleshooter. For more information, make sure to follow the options given below.

Option 1 – Restart your computer and try installing the Updates again

Restarting your computer can also help in fixing the Windows Update failed to install error 0x80073701. There are cases where the issue resolves on its own as it could just be some simple network or PC error.

Option 2 – Try to run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: 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.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening is less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 3 – Try to run the System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be causing the error 0x80073701. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow
• The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer.

Option 4 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073701. 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. After that, follow the next on-screen instructions and you should be good to go.

If you got the Microsoft Store error code 0x80072F30 while trying to open Microsoft Store, then it indicates that the Store fails to connect to the internet or is not able to launch successfully for some reason. It could be that the Windows Update Service has stopped or the Windows Store cache might be corrupted or it could just be due to a poor internet connection. Whichever the cause is, you have to fix this error so that you can use Microsoft Store again and you won’t be getting the following error message every time you open the app:

“Check your connection, Microsoft Store needs to be online, It looks like you are not, error code 0x80072f30.”

The error code 0x80072F30 is related to the Windows Store which prevents it from opening properly. To resolve this problem, you can try fixing the problem with the help of the options given below. Follow each one of them carefully.

Option 1 – Check your internet connection

The first and most obvious thing you can do is to check your internet connection. This may only be a basic tip but it sure works like a charm in most cases. And if you have another internet connection available, you can also try connecting to that and see if you can pull up Microsoft Store or not. 1] Change your internet connection: A basic tip, but sometimes works like a charm. You may want to check if your internet connection has an issue, or you can also try opening a website and see if you can open it and if possible try connecting to a different internet connection and see if the Microsoft Store opens for you. We also suggest you try changing your DNS and see if it helps.

Option 2 – Check the date and time as well as the time zone of your PC

A lot of services and apps rely on the Date, Time, and Time Zone of your PC which is why if they are not configured correctly, a request from the client machine will be rejected from the server and the same thing happens with the Microsoft Store.

• First, go to Settings > Time and Language.
• From there, check if it is set to Automatic or not – if it is, switch the toggle button off to set the Time and Time zone manually.
• Then select the right time zone manually.
• On the other hand, if the Time and Time zone is set manually, you have to switch the toggle button on to set Time and Time zone automatically.
• Restart your PC and afterward try opening Microsoft Store again and check if the problem’s fixed or not.

Option 3 – Run the Network Adapter Troubleshooter

Since Windows 10 is packed with various troubleshooters – one of which is the Network Adapter Troubleshooter – you can use it to troubleshoot the problem. To use it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 4 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again.

Option 5 – Check the Windows Update Service status

You might also want to check the status of the Windows Update Service since the proper functioning of this app depends on the Windows Update Service. It could be that there is some issue with the service which is why you’re getting the error code 0x80072F30 while trying to open Microsoft Store.

• Tap the Win + R keys to open the Run dialog box.
• Then type “services.msc” in the field and hit Enter to open Services.
• Next, look for Windows Update Service from the list of available services in Windows.
• Once you see it, check if its status is STOP or Pause and then change the status to Automatic.

It is no secret that a few days ago Facebook has been breach and tons of user accounts have been compromised. These kinds of things are very unpleasant experiences for both users and the company itself. User trust lowers significantly in the company and it can greatly increase the chances of users migrating to another platform. This just shows how much a hacker or security breach can produce damage to the business. Sadly we can not offer you guidance or assistance in recovering your stolen data nor can we provide you with removing your data from the hands of the attacker. What we can do is to provide you with information has your data been stolen. Threat actor released the personal information for 533,313,128 Facebook users on a hacking forum, including mobile numbers, name, gender, location, relationship status, occupation, date of birth, and email addresses. This data was originally sold in private sales after being collected in 2019 using a bug in the 'Add Friend' feature on Facebook. Facebook had closed this vulnerability soon after it was discovered, but threat actors continued to circulate the data until it was finally released practically for free. Since then, Troy Hunt has added the leaked data to his Have I Been Pwned data breach notification service to help users determine if a Facebook member's data was exposed in the leak. Go to the site and enter your email address to check and see if your data has been compromised.

About Potentially Unwanted Applications

Have you ever found an unwanted program on your computer system and pondered how it got there since you are sure you didn’t purposefully download and never gave authorization to be installed? A PUA / PUP (potentially unwanted application / potentially unwanted program) is a piece of software that comes bundled with freeware/shareware and you agree to install on your computer. These are programs you definitely don’t want on your PC since it doesn’t give any beneficial service. The term PUP was first coined to outline this downloadable crapware as something other than malicious software. The reason is, most PUPs get into a PC not because they slip via the security holes, for instance, but because the users have installed them by themselves – 100 % unintentionally needless to say. PUPs might not be malware but nevertheless, they are dangerous programs for your laptop or computer. At best, these types of unwanted programs provide hardly any benefit, and at worst, they can be quite harmful to your computer.

What do PUPs do on your PC, precisely?

Most Potentially Unwanted Programs comes in the form of adware, which typically aims to exhibit lots of annoying pop-up ads, banners, coupons, and bargains on web pages you explore. PUPS also comes in the form of unwanted toolbars or browser plug-ins. Not only they entirely take up space on your computer screen, but toolbars could also manipulate search engine results, track your surfing activities, decrease your internet browser’s overall performance, and slow down your internet connection to a crawl. They could appear innocent but PUPs tend to be spyware. And in the large majority of the cases, end-users will not be aware that they’re installing an unwanted program. These are software programs that don’t do anything useful to you; in addition to taking up space on your hard disk drive, they will also slow down your computer, often modify settings without your permission, and the list of frustrating features goes on and on.

How can you avoid ‘crapware’

• Read the fine print so that the end-user license agreement (EULA) you’re accepting is only for the program you actually intend to download. • Always choose “Custom” or “Advanced” installation and never blindly click the Next button, which should let you uncheck any “foistware” software programs you do not want. • Have a solid anti-virus program such as Safebytes Anti-malware that can protect your computer from PUPs. As soon as you install this software, protection from malware and PUPs is already turned on. • Avoid installing a freeware application you will not use. Nowadays ‘freeware’ isn’t actually freeware – but “crapware” bundling nonsense. • Don’t download software programs from pop-ups, online advertisements, file sharing websites, as well as other unreliable sources; look out for any preset, unwanted options when downloading the program. Avoid visiting blogs and sites that support pirated programs.

What To Do When You Cannot Install Any Anti-Malware?

Practically all malware is inherently unsafe, but certain kinds of malicious software do a lot more damage to your computer than others. Some malware is designed to interfere with or prevent things that you’d like to do on your computer.

For web browser plug-ins, go to your web browser’s Addon/Extension manager and select the add-on you intend to disable or remove. It is also advised to reset your web browser to its default state to fix corrupt settings. To ensure complete removal, find the following registry entries on your computer and remove them or reset the values accordingly. Please keep in mind that only professional users should try to manually edit the registry because removing any single critical system file results in a serious issue or perhaps a PC crash. Additionally, some malicious programs have the capability to defend against its deletion. Completing this task in Safe Mode is advised.

We tend to move and copy tons of files on our PCs and mostly, the process of copying or moving files, especially if the file has the size of 1GB or up, tends to take quite long. This may be caused by some issues which is why you face slow copy or move speed. So if you are experiencing this issue on your Windows 10 computer, then read on as this post will give you a couple of solutions you can try to increase the speed in copying or moving files. Follow the given instructions below.

Option 1 – Try to change the USB port

You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it. It may sound nothing but changing the USB port can actually improve the copying or moving speeds drastically so this should be the first thing you can try to speed up the process of copying or moving files.

Option 2 – Update the USB Controller Drivers

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
• Restart your PC and then click the “Search automatically for updated driver software” option.

You also have the option to update the motherboard and the USB driver from the manufacturer’s official website.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.
• From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 4 – Try to disable Windows Auto Tuning

Disabling Windows Auto-Tuning can also help in increasing the copying or moving of files in your computer. It is said that this feature improves the performance of programs that receive TCP data over a network by adjusting the receive buffer size dynamically throughput and latency of the link. Thus, if you are trying to copy some data over the network, then the Auto Tuning feature is playing a role here. And in some cases, disabling this feature completely resulted in a lot faster copy speeds over the network.

Option 5 – Try changing the USB Removal Policy

• First, plug your USB drive or external device into your PC and then open This PC.
• Next, right-click on your device and select Properties.
• After that, go to the hardware tab and select the storage media that you want to enhance and then click on the Properties button.
• From there, you can select the Better performance option if you wish for your device to have a better performance. Once you select this option, it will enable write caching in your Windows 10 computer but you need to use the “Safely Remove Hardware” option from the notification area to safely disconnect the device otherwise it may result in data corruption.

Option 6 – Format your drive

• To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
• Next, right-click on the drive and select Format.
• After that, uncheck the “Quick Format” option and then format your drive properly.
• Now once the formatting process is finished, unplug the drive and plug it back in afterward.
• Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select initialize disk.
• Next, select the correct partition type and proceed.

Once a tedious and unfriendly task of installing fonts has been severely made easier and more user-friendly. As technology advances daily so do some tasks. One of these tasks which today look unnecessarily complicated is fonts installation in Windows. What was once complicated navigation to control panel with an administrative account, today is two-click with the mouse anywhere, well anywhere on your hard drive, but still a great improvement nonetheless. Ok, so you have found cool new font which you like very much and you are eager to try it out, but how do you install it in Windows so your other software can find it and use it? The task is incredibly easy, let's presume that you have downloaded desired font or fonts to your hard drive from the internet, they are nicely placed in a folder, all you have to do is select which one you would like to install, right-click on any one selected and click on install. That's it, that is all that you need to do. Now in order to remove fonts first, you will have to go to the folder which has all fonts installed in the system. The location of this folder is conveniently enough c:\Windows\Fonts. In there select all fonts that you would like to uninstall from the system and simply delete them, that's it.

In the Windows ecosystem, MS Surface laptops are among the best laptops on the market, they are regarded as equivalent to Apple MAC laptops but for Windows. Microsoft Fall 2022 Event will be held on October 12th at 10 AM. The event itself will be held right before it kicks off its annual, developer-focused Ignite event in Seattle from that same day through October 14.

This event is the first in-person event that Microsoft has held since the beginning of the pandemic. We expect the launch of the Surface Pro 9 and the Surface Laptop 5, and maybe Surface Studio 3 as well. There are also some rumors about products themselves like choices between an ARM or x86 CPU but nothing is confirmed so far, we can just wait and see.

If you like to schedule different tasks on your Windows 10 computer and automate them, then you would find the Windows Task Scheduler very useful. It is commonly used by a lot of users to schedule various tasks like scheduling periodic execution of scripts and some programs to make sure that the intended tasks are automatically carried out. Apart from being a preinstalled application, the Task Scheduler is already available on your computer. However, there are times when you might encounter some errors while using it. One of these errors is error 0xFFFD0000. You can encounter this error while executing some PowerShell scripts. It can occur to any tasks as well especially to the ones that have a file executed using a particular program. And just like the PowerShell script, files also use PowerShell to be executed. To fix Error 0xFFFD0000, you need to follow the instructions provided below carefully. Step 1: In the Start Search, type “task scheduler” and click on Task Scheduler from the results to open it. Step 2: After opening Task Scheduler, right-click on the task that’s giving you the error and then click on Properties. Step 3: After that, navigate to the Actions tab in the new mini window that appears. Step 4: From there, select the action for the task and click on the Edit button which will open another mini window. Step 5: Next, make sure that the path to the executing program is properly typed inside the field of Program/script. Note that it should be set to the executable file for that particular program. For instance, you have to set it to “C:WindowsSystem32WindowsPowerShellv1.0powershell.exe” for the Windows PowerShell program. Step 6: You can also utilize the Browse button and navigate through Windows Explorer to locate that particular executable file for the program. Step 7: Now make sure to use the file argument in the Add arguments field followed by the path of the file to be executed. It should look like this:

-file "C:/Users/Ayush/Desktop/Powershell Script Sample.ps1"

Step 8: Once done, click on OK to save the changes made and see if the task is still giving you an error or not. On the other hand, if you are still getting the same error, you can try to repair the Task Scheduler by deleting corrupted tasks. Note that a single corrupted file can cause big problems so this option is quite important. And for you to delete a corrupted task or any task from the Task Scheduler, you have to use the Registry Editor if you are not able to use the Task Scheduler interface. To do so, follow these steps:

• Tap the Win + R keys to open the dialog box for Run.
• Next, type in regedit and click on OK or tap Enter to open the Registry Editor.
• Then navigate to this path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTree

Note: In this path, you can see all the tasks that are currently set in the Task Scheduler. And since it would be hard to tell which one of them is corrupted, you have to delete the latest one in Task Scheduler last. But before you do so, make sure that you take a note of the ID of the tasks. And for you to get the ID, you have to select the task you wish to delete and double click on the ID string located on your right-hand side, and then copy it in the Notepad.

• Right-click on the task name and then delete it.
• After that, delete the very same GUID which you have copied earlier from these folders:
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheBoot
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheLogon
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheMaintenance
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCachePlain
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTasks

Note: You might not see the same GUID from these folders but if you see it, delete it right away.

• Next, navigate to this location: C:WindowsSystem32Tasks
• Delete the very same tasks you just deleted from the Registry Editor.
• Restart your PC and check if the Task Scheduler is back to its normal state or not.

Error Code 0xC004C020 (Code 0xC004C020) – What is it?

Error code 0xC004C020 (Code 0xC004C020) is an error that occurs when you attempt to activate a copy of Windows 7 with a key, but the key has already been activated multiple times.

Method Three

Error code 0xC004C020 occurs if you have used your Windows 7 activation key on multiple computers, or multiple times on the same computer. You are not allowed to exceed the uses of the key—you should consider purchasing a new key if this is the case. A Windows 7 key is available for purchase online through the Microsoft website, in the shop section. The new product key must then be activated within 30 days, or it becomes no longer valid. It can be activated online or through the telephone. If it is not activated on time, features will stop working until the new key has been activated. This should be the last resort method, as you should not have to purchase a new Windows 7 key code if it is not necessary.
