If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL
• SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)

In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named sys and rename it to CMUDA.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the CMUDA.sys Blue Screen error is now fixed.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• After that, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

On the other hand, you can also try running the online Windows 10 Blue Screen troubleshooter from Microsoft. It is a wizard that could help you fix any Stop errors related to the CMUDA.sys file and will offer you helpful links as you use it.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • 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.

Option 5 – Run System Restore

Running System Restore might also help in fixing Blue Screen errors related to the CMUDA.sys file.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.

In case you don’t know, Microsoft hooks up every machine that is running Windows 10 with an Advertising ID which helps them in providing Windows 10 users with relevant ads. These ads are delivered to users in the Action Center, Start Menu as well as the ads inside the UWP Applications. What makes these advertisements relevant is that they keep track of your browsing trends, likes and dislikes, with the help of the Advertising ID. However, if you are not fond of advertisements and you do not want this feature of Microsoft to track your usage, worry not for you actually have the option to disable targeted ads on your Windows 10 computer by turning off the Advertising ID. And you can do that during Windows 10 Setup or using the Group Policy Editor. For more details, refer to the instructions provided below for each one of the methods.

Option 1 – Turn off Advertising ID during Windows 10 setup

If you are about to install Windows 10, then during the installation process, your computer boots into the Install and Configure Windows 10 screen with Cortana that assist you during the setup. Once you reach the last page which is “Choose privacy settings for your device”, you will see the Advertising ID of your computer. Under the Advertising ID, you have to disable or toggle off the “Apps can use advertising ID to provide more personalized advertising in accordance with the privacy policy of the app provider” option. After you disable it, click on the Accept button to proceed with the installation. After that, the copy of your Windows 10 you are using will have the Advertising ID disabled by default.

Option 2 – Turn off Advertising ID via Group Policy Editor

• First, tap the Win + R keys to launch the Run utility.
• Then, type “gpedit.msc” in the field and click OK or tap Enter to open the Group Policy Editor.
• Next, navigate to this group policy setting: Computer Configuration > Administrative Templates > System > User Profiles
• Now double click on the “Turn off the advertising ID” option and set the radio button to Enabled. Once you do, you will see the following description on your screen:

“This policy setting turns off the advertising ID, preventing apps from using the ID for experiences across apps. If you enable this policy setting, the advertising ID is turned off. Apps can’t use the ID for experiences across apps. If you disable or do not configure this policy setting, users can control whether apps can use the advertising ID for experiences across apps.” Note that setting the radio button to Enabled or Not Configured will turn off the data collection of the Advertising ID.

• Finally, exit the Group Policy Editor and then restart your computer to apply the changes made successfully.

Solution

Further Information and Manual Repair

Error Code 0x8007007B usually occurs when a product key has been activated too many times. Blocking activation aids in avoiding abuse of the key. If abuse of the key is not the case, it is possible to get the key reset, or you may receive a new key altogether. When you are not sure that you can complete these methods yourself, as they do contain advanced steps, it would be wise to consult a computer repair technician to avoid making the problem any worse.

Generally, the solution can be simple; it is just dependent on how comfortable you are with getting technical in your computer. Volume licensed media means that the media has a preset number of times that it is allowed to be activated. This helps to avoid misuse of the product. Some people install the Windows 10 program multiple times on their computer if they are software developers or do certain types of software testing. It is important to know the cause in order to effectively find the solution.

Method One:

1. From the desktop screen, press the Windows key and S, type “Command Prompt”. Then, right-click on Command Prompt in the results. Select Run as Administrator.  Click Yes when asked about requesting permission.
2. In the Command Prompt box, enter the command: slmgr.vbs -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
3. The x's represent the product key. Replace these with your unique product key.
4. Type in the following command into the “Command Prompt” window: slmgr.vbs -ato
5. Click Enter
6. Restart your computer and try to activate windows again. It should not show the error code anymore.

Method Two:

1. While on the desktop, press the Windows key and R.

2. The command will complete the tasks. This will take some time so just let the computer do its thing and work. Let the sfc finish the scan.
3. When the scan is complete, restart the computer.
4. Check for the activation. The error code should be gone at this point.
5. If it is gone, revisit Method One or move on the Method Four.

Method Four:

Call the Microsoft Support Team and explain the problem in as much detail as you can give. Give the team the error code 0x8007007B and ask to have a different product key. When they give you the new product key, repeat Method 2. The Microsoft Support Team will either change your product key, or they will reset your current product key so that it can be used for activation again.

What is Error 0xc0000142?

Error 0xc0000142 can occur in any of the Windows versions and usually occurs when an application fails to properly initialize.

This error can be critical for a computer as it signifies that the system is unstable. Error 0xc0000142 can cause slow performance in a PC, system freeze, startup and shutdown issues, blue screen and errors in installation.

Solution

Error Causes

Windows/Application Error 0xc0000142 can occur because of a number of reasons.

When a computer is an overload with data, or when system files get broken or missing, this error can occur and will result in startup and shutdown issues as well as the blue screen. Another reason, and one which is quite common, is improper computer maintenance.

This will cause a PC to perform slow, system freezes, and installation errors. This error displays ‘failed to initialize’ on either a Windows error box or the blue screen of death.

Further Information and Manual Repair

Error 0xc0000142 can occur at any time, but there are many ways to resolve it. For instance:

1) Clean the Registry

A corrupted registry is one of the major reasons why this error occurs. The registry is used by Windows to store information and settings on the computer, which is why it has a large database.

This database contains emails, wallpapers, saved passwords and much more in ‘file path references’. These allow Windows to run the common files in your system. A registry cleaner can fix any errors in the registry database.

2) Malware Scan

Viruses can cause certain applications to not function properly. Hence, download a strong antivirus and run a deep scan on your system and remove any potential infections and spyware.

3) Reinstall Applications

Non-critical applications in a computer are those that are installed by the user. If error 0xc0000142 displays in any of your installed programs, then you should reinstall these programs. Often applications have damaged or corrupted files which can slow them down. To resolve this, follow these steps:

• From Start, click on Control Panel
• Go to Add/Remove Programs and uninstall the programs
• Restart your PC and reinstall the program

The third step is not recommended in case the error is caused by cmd.exe

4) Repair Windows

If the error is still on display despite following the previous steps, then you can repair Windows. This process allows Windows to retain all your data and information by simply replacing the program files and settings with fresh ones. This can stop error 0xc0000142 by allowing the programs access to use necessary files smoothly and effectively.

If you cannot resolve the error in any of these steps, then there is another way to do so if you have a computer that runs the Microsoft Internet Security and Acceleration (ISA) Server 2000. Follow these steps in order to resolve it:

• Make sure that in Program Files and Microsoft ISA Server, a Clients folder exists. The ISA Server service will run on this folder
• Confirm that Administrators and SYSTEM have Full Control assigned in the Program Files/Microsoft ISA Server/Clients folder
• Confirm that Msplat.txt file is in the Clients folder. You can copy this file from other ISA Server computers if it is missing
• If the Clients folder is damaged or is missing, or if you can’t copy the Msplat.tct file from another ISA Server computer, then reinstall the ISA Server 2000

Windows 11 comes with glass and transparency effects by default once it is installed. The transparency effect looks really good but if in any case, you do not like them, you can easily turn them off very easily

1. Open settings inside Windows 11
2. Inside settings click on Accessibility in the sidebar
3. Click on Visual Effects on far-right
4. Inside Visual effects, settings click on the switch beside Transparency effects to OFF

Windows will automatically save settings and apply changes right away. Just close your settings application and continue with work. You can always turn it back ON if you change your mind.

Windows 11 has been officially presented during Microsoft’s virtual event on June 24^th. Since presentation internet has been pretty live and busy with a discussion about it, some discussions are positive, some not so much but that is expected and it happens always when a new product is presented. One of information that we have about Windows 11 is tied to the home edition of this OS, Windows 11 home edition will require an internet connection at setup, and a Microsoft account in order to be installed and used. Previous versions of Windows could be installed and used with local accounts but it seems Microsoft has abandoned that idea for its new OS. OS will be delivered mostly as updates or via internet download so internet and online requirement make sense but why it cannot use the local account and must have a Microsoft one is beyond me.

Kernel Mode Heap Corruption is the error message that the Windows operating system throws when it encounters a blue screen of death or BSOD error during PC startup or launching specific programs such as video games. It is mainly caused due to software conflicts, driver issues (especially graphics card driver), and computer hardware malfunctioning. The good news is that this error is easily fixable. Follow the next steps in order to fix the error:

1. Rollback graphic card driver

   Press ⊞ WINDOWS + X to open Windows secret menu and click on device manager Expand Display adapters section Right-click on your GPU and choose properties In properties window go to the driver tab and click on Roll back driver Select the reason for operation and click on YES Reboot your PC

2. Update corrupted and outdated drivers

   How is this error mostly driver issue, updating and fixing bad drivers can fix it very easily. As in the previous step, you will need to open the device manager and go through all drivers and manually check for updates for each one, update as necessary or reinstall ones you might think have gone rogue. If you are not experienced enough with this kind of task install some automatic solution for this task like DriverFix

3. Check for software issues

   If this error started happening after the installation of new software it is very likely that the application is causing problems. Try uninstalling or disabling the application to see if it will fix the issue. You can also boot Windows in safe mode to see if the error will happen there, if Windows is working fine in safe mode, it is likely that issue is on the software side.

4. Run SFC scan

   Press ⊞ WINDOWS + X and choose Command prompt (admin) In command prompt type in sfc /scannow and press ENTER Wait for the process to be finished and Reboot the system

Experiencing issues while using Remote Desktop connections is not uncommon. One of the issues that users encountered recently while trying to connect to their Remote Desktop network is the error saying, “Your credentials did not work, The login attempt failed”. If you are one of these users, then you’ve come to the right place as this post will walk you through fixing the problem. When facing this kind of problem, the first thing you can try before you do some troubleshooting steps is to verify the credentials. But if you are certain that you’ve entered the correct credentials just like what other users reported, then it’s completely a different matter. Based on the reports, this error is common on newly installed versions of Windows 10 or after reinstalling the operating system which could mean that the problem might be due to the Windows security policies or the username might have been recently modified. The latter case is a possibility especially if you’ve reinstalled Windows 10 and had entered a new username. In such a case, you will really have a difficult time connecting to your Remote Desktop connection since its credentials do not really automatically change. If you’ve verified that your credentials are correct, then now’s the time you troubleshoot the problem with the help of the potential fixes provided below. Just make sure that you follow each one of them in sequence.

Option 1 –Try to run the Network Adapter troubleshooter

To run the Network Troubleshooter, refer to 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.
• Restart your computer.

Option 2 – Try to change the network profile from public to private

According to some reports, this error occurs on systems where the network profile was set to public. Thus, you need to change the network profile to private to resolve the problem. How? Refer to these steps:

• Go to Start and from there click on Settings > Network & Internet > Status.
• Next, click on the “Change connection properties” option.
• After that, set the radio button of Network Profile from Public to Private.
• Wait for a couple of seconds until the system is done applying the changes you’ve made and then see if you can now connect to the Remote Desktop connection.

Option 3 – Try changing the account username

As mentioned, one of the possible causes for this error is the reinstallation of the operating system. You might have changed the username for the system but it does not really change the username of the Remote Desktop connection as well. Thus, you have to change the username back to what it was before you’ve reinstalled Windows 10.

Option 4 – Try modifying the Windows Security Policy

You can also try to edit the Windows Security Policy as it could help in resolving the error. This Windows Security Policy, when enabled, will not allow non-admin users to log on to the Remote Desktop connection. So if you want to allow non-admin users to use the Remote Desktop connection, then you need to modify this policy. Note that you can only do that if you are the admin of the system yourself.

• Tap the Win + R keys to open the Run utility.
• Then type “secpol.msc” in the field and tap Enter or click OK to open the Local Security Policy.
• After opening the Local Security Policy window, select Local Policies > User Rights Agreement located on the left pane.
• Next, double click on “Allow log on through Remote Desktop Services” located in the right pane.
• And in the next window that appears, select Add user or group.
• After that, type in the username of the intended non-admin user under the “Enter the object names to select” column.
• Once done, click on the Check Names button to fix the username and then click OK to save the changes made.
• Restart your computer.

Option 5 – Use the Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and then type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• Next, navigate to this path: Computer Configuration > Administrative Templates > System > Credentials Delegation.
• Double click on the “Allow delegating default credentials with NTLM-only server authentication” policy setting located on the right pane to edit it.
• After that, shift its radio button to Enabled and click on Show.
• Then type “TERMSRV/*” in the Value box and click OK.
• Now repeat the same for the following policy settings:
  • “Allow delegating default credentials”
  • “Allow delegating saved credentials”
  • “Allow delegating saved credentials with NTLM-only server authentication”

• Once you’re done, restart your computer and see if the problem is fixed.

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.
