Kernel Mode Heap Corruption Error in Windows

Windows Updates are checked for their validity every time they are downloaded from Microsoft servers just like how browsers check websites for a valid certificate. And so if you got an error message saying, “ Some update files aren’t signed correctly, error code 0x800b0109 ” while trying to update your computer, it indicates that the Windows service was unable to verify the validity of the Windows Update. To fix this error, you can try out the options prepared in this post.

Option 1 – Reboot your computer and try again

Save your work and reboot your computer and then try checking for updates again. In some cases, all you need is a restart to fix errors like error code 0x800b0109.

Option 2 – Try to update Windows after an hour or so

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it an hour or so before trying to run Windows Update again.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like Error 0x8007001E. 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.

Option 4 – Delete the contents in the Temporary folder

You can also try deleting the contents in the Temporary folder – all the downloaded, pending, or failed Windows 10 updates. You can do that using the simple and easy steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “%temp%” in the field and press Enter to open the Temporary folder.
• After that, select all the folders and files within the Temp folder and delete all of them.

Option 5 – Clear the contents in the Software distribution and Catroot2 folders

• Open the WinX Menu.
• From there, open Command Prompt as admin.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go 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.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 6 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• 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”.

  • Allow users to log on using Biometrics.
  • Allow domain users to log on using biometrics.
• Now exit the Group Policy Editor and restart your computer to apply the changes made properly.

Error Code 0x8007232B (Code 0x8007232B) – What is it?

Error code 0x8007232B (Code 0x8007232B) is an error that occurs when you attempt to activate Windows Server 2008 or Windows Vista.

Common symptoms include:

• Attempting to activate Windows 7, Windows 8, or Windows Server 2012 and you receive an error message.
• The error message says: “Windows could not be activated. Key management services host could not be located in domain name system, please have your system administrator verify that a KMS is published correctly in DNS”
• The error message says “The directory name, file name, or volume label syntax is incorrect”.

Error Causes

• Error Code 0x8007232B occurs when you attempt to use media that is volume licensed to install: Windows 8, Windows 7, Windows Vista Enterprise, Windows Vista Business, Windows Server 2012, Windows Server 2008, Windows Server 2008 R2.
• This error code also occurs when the activation wizard is unable to connect to a Key Management Service host computer.

Further Information and Manual Repair

Error code 0x8007232B can be seen when you are trying to activate windows, on several different operating systems. This problem can usually be easily corrected, but in the event that it can't, please contact a computer repair technician. When you try to install any of the previously mentioned Windows products, they use a generic product key to install the volume-based license software. If you do have a KMS host computer configuration and see these error codes, that means the correct DNS entries are not being seen on the computer. If there is not a KMS host computer setup, you need to do this setup, otherwise switch to a MAK product key method, and activate the volume license installation that way.

Method One:

Using a Multiple Activation Key as opposed to KMS activation

1. Click the Start icon, click on All Programs, click on Accessories, right-click on Command prompt.
2. Click on “Run as administrator”. Type in the password or provide confirmation if prompted for administrator password or confirmation.
3. When asked for the command prompt, enter in the following and then hit the Enter buuton: slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx  Note: this placeholder represents the MAK product key.

Method Two:

Configure a KMS host server for the clients to activate against.

A KMS host server needs to be configured for the clients to activate against. When there are no KMS host servers configured near you, install and activate a KMS server key. After this, configure a computer on the network to host this KMS software and publish the Domain Name System (DNS) settings.

Method Three:

When the client cannot locate a KMS host on the network for activation:

1. Verify that your computer has the KMS host installed and activated by using a KMS key that is registered in DNS. You will follow these steps to do that:

1. Click the Start button, click on All Programs, click Accessories, and then right-click on Command Prompt.
2. Click on Run as Administrator. Type the password or provide confirmation if you are asked for an administrator password or for confirmation.
3. In the command prompt box, type the following command and press ENTER: nslookup -type=all _vlmcs.tcp>kms.txt
4. Then open the KMS.txt file generated by this command. The file will contain at least one entry that relays the SRV service location.

2.  A KMS host server registers a DNS SRV record once every 24 hours by default. You should check the registry to see if the KMS host server is registering with the DNS. Follow these steps to do so:

1. Click on Start, type in regedit, and then press Enter.
2. Locate HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionSL and then click on it.
3. The KMS server does not register in DNS if the DisableDnsPublishing subkey is existing and has a value of 1. If this subkey is missing altogether, create a DWORD value called the DisableDnsPublishing. If the dynamic registration is suitable, the subkey value should be changed to 0. Right-click DisableDnsPublishing, click on Modify, enter 0 into the Value data box, and click OK.

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.

Error Code 0x8007267C – What is it?

Error code 0x8007267C is specific to Windows 10. This error is triggered when no DNS server is currently configured in your network settings during the Activation process. If you are fairly confident in your ability to address command-line tools and networking issues, you can follow the steps below to try to remedy the error code on your own. If not, you may need to contact a qualified technician in order to resolve the error successfully.

Solution

Error Causes

The cause of Error Code 0X8007267C within the Window 10 system is fairly straightforward. Windows Activation requires a valid DNS server to be configured in order to complete the Activation process; if one is not available or properly configured, then you may see this error code and Activation will fail.

Further Information and Manual Repair

The following methods may help you to resolve this error, but you’ll need to have some familiarity with command-line tools to complete the steps successfully. If these methods do not work or if you are uncomfortable in using the command prompt, you may need to consult a technician to fully resolve this particular error code on the Windows 10 system.

Method 1: Register a DNS server within your network properties and test the connection.

In order to resolve this error code, client connectivity to a DNS server must first be established. The following steps may help you to determine the root problem with your connectivity status:

1. Open a command prompt, after which you'll run IPCONFIG /all
2. Verify the following values: The IP address that has been assigned, the DNS server, the subnet mask, and the default gateway. Compare each to ensure that all are set with the values that correspond to your specific environment
3. Check for basic IP connectivity to the DNS server using the PING command. In using the PING command, utilize the address of the DNS server found in Step 1

ping <DNS Server IP address>

If basic connectivity to the DNS server in question is failing, then you will need to resolve that issue before going further in the process.

After troubleshooting the above basic connectivity issues to the DNS server, you can reattempt Windows Activation by using the command below from within an Elevated Command selection:

cscript windowssystem32slmgr.vbs -ato

If the steps above did not work for you, you may want to try the steps found in method 2.

Method 2: Use phone-based authentication with a MAK (multiple activation key).

If a DNS server is not connected to your network, you can use an alternative method to complete the Windows Activation process. Bypass Method 1 by using a MAK product key instead to activate the volume license installation. Certain MAK product key providers have a variation on the specific key numbers that you will need to use. If you are using TechNet media or MSDN media, you will have to change the product key listed to the product key provided. The product keys provided by either TechNet media or MSDN media for Windows Server 2008 or for Windows Vista Enterprise will be the MAK product key that you will enter in a later step.

Like the previous method, you will need to have some familiarity or confidence in your ability to operate Command Line tools before proceeding. Once you have found your MAK product key, you’ll need to open a command prompt and use the following command to change the product key to match the MAK product key, which should look something like the example below:

            slmgr –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

After completing the product key change, use the following command to initiate the phone activation wizard, thereby completing the activation of the system:

            slui 04

The activation wizard should be able to walk you through the remainder of the process in a step-by-step manner. In addition to appearing as an error code in Windows 10, this particular error may apply to multiple versions of Windows, including:

• Windows 7 Enterprise
• Windows 7 Enterprise E
• Windows 7 Enterprise N
• Windows 7 Professional
• Windows 7 Professional E
• Windows 7 Professional N

Steps to address the error code may be different in any of these other versions of Windows. If you have difficulty in resolving the error effectively, seek professional technical help.

If you connected headphones to your Windows 10 computer to listen to audio but when you check it in the playback devices, you’re not able to find it, read on as this post will guide you in what you can do to figure out what exactly caused this kind of problem and how you can resolve it. This kind of issue could simply be with the headphone itself or the headphone port or your operating system. So if it turns out that the problem is with the hardware, you might have to replace the components. However, it is recommended that you troubleshoot the problem first before doing that. The most basic thing you can do is to try changing the headphone port, although this can be quite difficult since most computers don’t have any extra port for headphones if your computer has one, then give it a go. If it still didn’t work, follow each one of the options provided 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 Audio inputs and outputs.
• 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.
• Then also click on the option, “Search automatically for updated driver software.
• Restart your PC after the installation.

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 enabling the headphones from the playback devices

• Tap the Win + R keys to open the Run dialog box and type the “CPL” command.
• Tap Enter to open the Playback devices.
• Next, right-click on any open space section and check the boxes for the “Show Disconnected Devices” and “Show Disabled Devices” options.
• After that, this should help in displaying the headphones in the section of Playback devices.
• And if they are disabled, you can just right-click them to have them enabled.

The number of Hertz is the number of how many images your screen draws in one second. So monitor with a refresh rate of 60Hz will draw 60 images each second on your screen. To most users, this will look fine and enough but actually, if you would place them in front of a 120Hz screen difference will be visible right away.

Benefits of higher refresh rates

In most simple words just looking at a screen that has a higher refresh rate will produce a more natural feel of things, although some people would argue that flickering can not be seen on 60Hz monitors and that should be enough, I would argue that they never watched the movie, played the game or used high refresh rate screen when they can state something like that.

Yes, 60Hz might be enough to look at the web page or read some documents but long exposure to 60Hz can have a tiring effect on the eyes in the long run. 120Hz and above just feel more relaxed and it is far less demanding on the eyes. Watching movies also is much better on a higher refresh screen, with way much less motion blur in fast scenes giving the overall experience a greater natural feel.

Gaming is perhaps an area where a refresh rate of 120Hz and above will show its best. Having a higher refresh rate will be easier on your eyes and can even give you a competitive edge. When for example you have twice more images per second on your screen than your opponent his movement will be more fluid and predictable because of that and overall precision will be much higher when moving the cursor in the game since more frames per second means more precision and smoother movement.

The dark side of high refresh rates

After all the positive things that were said about the advantages of high refresh rates, it is just fair to look at some negatives or in this case only negative one and that is Computer power. As said in the previous section having a 120Hz refresh rate means having 120 frames displayed on the screen per single second. Having even higher monitors like 360Hz means even more frames per second and in order to actually see all of that frames you will need to have enough computer power to back it up. Having for example screen with a refresh rate of 240Hz means nothing if your GPU and rest of the computer are able only to push 150 frames per second, in this case, you will still have 150 frames in one second despite the monitor being able to go to 240.

Conclusion

Generally and with all of my heart I would recommend moving away from 60Hz monitors, yes they are cheaper and more affordable but at the end of the day if you are someone like me who spends most of his daily time in front of the computer you would be grateful to have higher refresh rate screen and save your eyes, and after all, why not enjoy some smoother and better movie and game experience as well as saving your eyesight.

Direct replacement for Apple M1 Chip is near. There were some M1 Chips versions like M1 MAX and M1 ULTRA that were upgrades of the existing M1 chip, but the new and upcoming M2 is something different and it is aiming to replace M1 completely.

Made in a 5-nanometer design, with 20 billion transistors and 100GB/s of unified memory bandwidth is meant to increase performance over M1. It has the same M1 8 core design with 4 high-efficiency cores and 4 high-performance ones.

All CPU and GPU cores are faster than their M1 equivalents and Apple states that when running M1 and M2 at the same power level M2 will perform 25% faster. The first version of the chip will place focus on power efficiency so if you are more on side of being a power user wait for the MAX or ULTRA version of M2.

Tech details of M2

M2 system on a chip like its predecessor M1 combines both CPU and GPU on a single chip with shared memory in order to increase performance compared to systems that have separate CPU and GPU. M2 so far has been only announced for MacBook Air and the 13-inch MacBook Pro that suppose to hit the market somewhere around July this year. Of course, we expect that M2 is included in future iPad series or Mac Mini series as well.

• CPU Cores: 8
• GPU Cores: Up to 10
• Unified Memory: Up to 24 GB
• Neural Engine Cores: 16
• Number of Transistors: 20 billion
• Process: Second Generation 5nm
