How to Repair BSOD Stop Error code 0xc000021a in Windows 10

If you encounter the “Setup has failed to determine supported install choices” error when trying to downgrade or upgrade your Windows 10 computer, this signifies that there are some compatibility issues with the installation process and that Windows was not able to either downgrade or upgrade to another version. Usually, this error occurs when you are using the built-in options in Windows 10 upgrade or downgrade to another version of Windows. This option is mostly used as it keeps the user settings as well as data intact. Thus, you need to keep in mind a lot of parameters before you proceed with the installation because if there is any conflict in the process, you certainly won’t be able to downgrade or upgrade your Windows computer. To resolve the issue, here are some suggestions that might help.

Option 1 – Try running in Compatibility mode

This is the first thing you can try to resolve the issue instead of going right ahead on making a bootable device. So if you are downgrading Windows, you can try to run the installer in the compatibility mode for that specific Windows version.

• Look for the setup file.
• Once you find it, right-click on it and select Properties from the context menu.
• After that, go to the Compatibility tab and mark the checkbox for “Run this program in compatibility mode for:” and from the drop-down list, select either Windows 7 or Windows 8.
• You also have to check the “Run as administrator” option.
• Now click the Apply button and then click OK to save the changes made and check if it has resolved the issue or not.

Option 2 – Option 2 – Try troubleshooting compatibility

This option is almost the same as the first one except it is an alternative way of fixing the “Setup has failed to determine supported install choices” error in case the first one didn’t work. In this option, you will troubleshoot the compatibility issue.

• Look for the setup file.
• Then right-click on it and select the “Troubleshoot compatibility” from the context menu.
• After that, click on the “Try recommended setting” option. Once the process is done, the error message should be gone.

Option 3 – Try to use the setup file instead of an image

If you are running the Windows ISO image for the installation, you can try running the setup file instead. This is because when you try to install Windows from an image file directly, it has to be loaded into a virtual CD drive first, and then from there, further operations are carried out. And so, you can just bypass this mechanism to avoid getting the “Setup has failed to determine supported install choices” error.

• First, you need to extract the disk file to an accessible location.
• After that, go to Sources > Setup.exe.
• Now run the setup file to upgrade or downgrade the Windows version. Just make sure that you do run the setup file as an administrator.

Option 4 – Try to do the upgrade or downgrade in a Clean Boot state

Putting your PC in a Clean Boot state can also help when you want to upgrade or downgrade your version of Windows without any trouble because, 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”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows Updates or upgrade again.

Option 5 – Try to use the Media Creation tool

The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

In the latest Windows 11 fiasco, it is reported that the operating system is slowing down some SSD drives. Good thing is that it does not affect all of SSD on the market but the ones which it is affecting can see even a 45% of speed drop. Microsoft has not published a solution to this issue, but users point out two potential problems. The first is a security mechanism based on disk virtualization, which is supposed to slow down the performance of SSDs. The second, in turn, is related to the place of installation of Windows 11 – users indicate that if the performance test is performed on a medium with no files associated with the system, its performance results are similar to the parameters given by the manufacturer. Transfer speeds were to be slightly improved with the latest Windows 11 update 22000.348. However, users are still waiting for a solution to the problem that significantly reduces the efficiency of SSD media.

More information

The details described leading to speculation that the problem could be related to drivers that Microsoft is providing. On further tests, all Nvme drives that use the Microsoft driver have this problem, but Intel 905P, which has its own driver provided by Intel, is working at full power,”.

Installing Windows updates, installing a new driver from the manufacturer, or even just installing an application or game can cause sometimes certain components of your computer to stop working properly or introduce issues that were not present just before mentioned installation. Luckily for all of us, Microsoft seems aware of this potential issue and we have the option to roll back an older driver which performed well and had no issues at all. In order to do this first press ⊞ WINDOWS + X to open the hidden start menu and click on Device Manager. From the Device Manager choose the troublesome device and right-click on it, choose properties. Device properties floating Window will appear. Click on the top tab which says, Driver. From the Driver tab, click on Roll Back Driver. Note that if the device is working properly, the Roll Back Driver button will be greyed out and you will not be able to click on it meaning that chosen device is not the issue. If the device is not working properly and you can click on Roll Back driver, do it, choose the previous version, and reboot your computer. You can use this method to get back to the previous driver version for any device that is causing issues in your computer.

What Is Error 126?

Error 126 is a very commonly occurring error that is often the result of damaged system files of Windows. They usually occur during the installation of some Windows program or application. When Error 126 is generated, it terminates the installation process almost instantly. It is important to take corrective measures immediately to ensure that no such problems are encountered again in the future.

Solution

Error Causes

There are a variety of conditions that may trigger Error 126. These conditions are listed below as follows.

• Corruption of the service-related DLL file
• Missing or damage service-related DLL file
• Corrupt, damaged, or Misconfigured system files
• Improper hardware or application installations or uninstallations
• Existence of viruses, malware, adware, or spyware in the system
• Corrupt or incorrect registry entries in the system files

When any of the above-listed conditions occur, the corrupt system files will go to the improper links or missing information. Eventually, the problems with the files will keep the applications or programs from responding in the usual manner. Whatever are the reasons for error generation, it is of utmost importance that the error is removed to ensure smooth functioning of the system.

Further Information and Manual Repair

There are many different ways this error can be rectified. However, the two most effective solutions are listed below as follows.

• This solution is for the advanced user. Turn on the system and log on to it as the Administrator. Now click on the Start button. Now click on All programs -> Accessories -> System Tools. Here you will come across the option for System Restore. Click on it. A new window will appear. Select 'restore my computer to an earlier time' point. Now clock on Next. A list of restore points will now appear in front of you. Choose the latest restore point you come across from this list and click on ‘Next’. In the next window that opens, click on ‘Next’ again. This is the confirmation window. Once the restoration finishes, restart your computer.
• This solution is for novice users. Download an Error 126 repair utility program. Install it on your system. Now use it to scan your system for errors.

As you know, Microsoft constantly releases new updates with the main goal of fixing bugs as well as deliver users with new and exciting features. However, there are times when the latest update comes with an unwanted bug. One of these bugs is an error message saying, “Low Disk Space. You are running out of disk space on Local Disk (G:). Click here to see if you can free space on this drive.” So if you have recently installed a Windows 10 update, then you’ll most likely see a completely new drive on your computer which will appear right after the installation of the update and you’ll also start seeing the aforementioned error message. It gets irritating as this error message keeps on popping up even if you still have a lot of free space on your other drivers. Obviously, the main reason why this error message pops up all the time is the bug brought along by the Windows Update. This bug unhides the recovery partition drive and allocates it a drive letter which is why you are seeing a new drive in your computer. Thus, you can get rid of the pesky error message by simply removing the letter of the new drive. Just remember that you must not delete anything from the recovery partition drive nor format the drive. Formatting or deleting the recovery partition drive can heavily affect the recovery of Windows since the data on the drive is used by the Windows Recovery Environment or your system’s manufacturer. A lot of users have reported that removing the drive letter has resolved the issue. And if you worry that removing the drive letter will delete the drive, you are mistaken. This solution is basically harmless and is proven effective to make the notifications go away. Carefully follow the instructions below to get rid of the Low Disk Space notification by removing the drive letter.

• Step 1: Tap the Windows key once.
• Step 2: Next. In the Windows Start Search, type in “command prompt” and right-click on Command Prompt from the search results and select the “Run as administrator” option or you could simply tap Win + R keys and then input “cmd” and hit Enter to open Command Prompt.
• Step 3: After opening Command Prompt, type in “diskpart” and tap Enter.
• Step 4: Next, type in “list volume” and tap Enter. After that, you will see a list of drives.
• Step 5: Take note of the letter associated with the newly created drive.
• Step 6: Afterwards, type in “select volume <drive letter>” and tap Enter. Take note that you must replace the <drive letter> with the drive letter you’ve found in Step 5.
• Step 7: Now type in “remove letter=<drive letter>” and then tap Enter. Once again, replace the <drive letter> with the letter you took note of in Step 5.

If your Windows PC encounters an error, it will display a Blue Screen of Death or BSOD error which usually comes up for a fraction of second and creates some logs or Dumps Files as what other user prefers to call it and then boots your PC suddenly. This process usually takes place quickly that most users find it hard to get the error code and won’t probably be able to check what really went wrong with their PCs. This is where the dump files come in. They are stored internally in your computer and can only be accessed by an administrator. They are classified into 4 main types and in Windows 10 they are either:

1. Complete Memory Dump
2. Kernel Memory Dump
3. Small Memory Dump (256 KB)
4. Active Memory Dumps

Dump Files are useful as they could help you in resolving the problem and so you need to configure your Windows 10 PC to create them but first, you need to make a system restore point. This is essential as you are about to modify some system files as well as critical Windows 10 settings. There are two ways you can create Dump files – first is by modifying the settings in the Startup and Recovery and lastly is via the WMIC command line. Refer to the instructions prepared below to be guided on how you can create Dump files after any BSOD error using these options.

Option 1 – via Startup and Recovery

• Type in “control panel” in the Cortana Search box and then click on Control Panel from the search results to open it.
• After opening Control Panel, you need to make sure that you view the contents by their Category then click on the header link which is labeled “System and Security” or you could also right-click on the This PC icon and then click on Properties.
• Next, select the Advanced system settings from the left panel. Once you do, a new and small window will pop up.
• Under the newly opened window, look for the section called Startup and Recovery and then click on the Settings button.
• And from the System Failure section, you can choose any option from the drop-down for Write debugging information such as:
  • None – this means that there is no dump file created by Windows
  • Small Memory Dump – this means that Windows will create a Minidump file on BSOD
  • Complete Memory Dump – this means that Windows will create a Complete Memory Dump file on BSOD
  • Automatic Memory Dump – this means that Windows will create an Automatic Memory Dump file on BSOD
  • Active Memory Dump – this means that Windows will create an Active Memory Dump file on BSOD

Note: The complete dump needs a page file that is allowed to be the size of the physical memory installed in your PC with a dedicated 1 MB of space for just the page header.

• Now once you have selected the most suitable option for you, just click on OK/Apply and then exit.
• Restart your PC to successfully apply the changes made.

Option 2 – via the WMIC command line

• The first thing you need to do to create Dump files via the WMIC command line is to tap the Win + X keys combination or simply right-click on the Start button and then select the Command Prompt (Admin) option. You could also type in “cmd” in the Cortana search box and then right-click on Command Prompt from the results and select Run as administrator.
• After that, type in any of the commands given below depending on your preferences so that your Windows 10 PC will be configured to create Dump Files:
  • No dump file: wmic RECOVEROS set DebugInfoType = 0
  • Small Memory Dump: wmic RECOVEROS set DebugInfoType = 3
  • Kernel Memory Dump: wmic RECOVEROS set DebugInfoType = 2
  • Complete Memory Dump: wmic RECOVEROS set DebugInfoType = 1
  • Automatic Memory Dump: wmic RECOVEROS set DebugInfoType = 7
  • Active Memory Dump: wmic RECOVEROS set DebugInfoType = 1

Note: A complete dump has to have a Page file which is allowed to be the size of the physical memory installed on your PC accompanied by a 1 MB space for just the page header.

• Now type in “exit” in the Command Prompt to exit it.
• Restart your PC to apply the changes made successfully.

Instaling and removing applications from your Windows can sometimes leave some traces that are unpleasant and can cause annoyances. One of these annoyances is the program in the startup section of the task manager.

If you ever opened task manager and went into the startup section trying to disable some of the startup items on your Windows boot there might be a chance that you have experienced and seen a program without any icon or information about it just sitting there.

This is due to some applications being removed from the system but for some reason, it still shows itself in startup and it is quite annoying. So here we will show you how to get rid of this annoyance so your startup is clean again without junk in it.

Removing a program from startup

Locating the source of the issue

The first thing of course is to open the task manager itself and navigate to the startup tab. Inside the startup tab right-click on the column header and tick or enable Startup type and command line. Now you will see the location of the supposed file (that is missing or you could just go there by right-clicking on the item, but here it is greyed).

99% of the time startup type will be registry since the file is missing, if it was a file fix would be just to simply delete the file in the folder but since it was installed and not properly removed registry key is still present but the file cannot be found. After confirmation that the file is indeed missing and that the startup type is registry open the registry editor by typing Regedit in search and pressing enter.

Removing the key from registry

Inside Registry editor navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Inside on right part, you will see all auto-start entries added by installed applications.

Locate one that is causing issues by comparing its path with the path inside the task manager command line and delete the key. Once the key is deleted right-click on RUN on the left part and choose HKEY_LOCAL_MACHINE to quickly jump on that key location and repeat the process of key deletion if needed. HKEY_LOCAL_MACHINE will delete startup entry for all users and sometimes entry will not be present here since the application is not installed for all users or there are no other users on the machine.

After the procedure is finished, reboot your systems in order to apply changes.

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.

What Is Runtime Error R6034?

Recently, several users reported an issue on their Windows 10 computers where the taskbar is not visible when they tried to connect to a computer via Remote Desktop Protocol or RDP. The Remote Desktop Connection feature uses the RDP which allows users to access a computer remotely. This is actually different from the taskbar being hidden automatically until the pointer hovers on it since, in this scenario, the taskbar is completely not accessible which makes using the remote computer entirely difficult, if not impossible. There are several suggestions you can check out to resolve this problem, you can try to restart the process of Windows Explorer via Task Manager or you could clear the cache for multiple processes. You could also try to reinstall the Shell Experience components or show the local taskbar in the Remote desktop. Moreover, you could also try to update, uninstall or roll back the display driver/graphics card driver. For more details, refer to each one of the options given below.

Option 1 – Try to restart the Windows Explorer process

The first option you have to try to fix the problem with the taskbar is to simply restart the Windows Explorer process in the Task Manager.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Processes tab and find the process of Windows Explorer.
• Once you find it, right-click on it and select Restart to restart its process.
• After that, restart your computer and see if you can now see the Taskbar.

Option 2 – Try clearing the cache of multiple processes

The next thing you can do to resolve the problem is to clear the cache of many processes in your computer. To do so, follow these steps:

• Open the Notepad app and paste the following content in the text area:

@echo off taskkill /f /im explorer.exe taskkill /f /im shellexperiencehost.exe timeout /t 3 /NOBREAK > nul del %localappdata%PackagesMicrosoft.Windows.ShellExperienceHost_cw5n1h2txyewyTempState* /q timeout /t 2 /NOBREAK > nul start explorer @echo on

• After that, tap the Ctrl + S keys to save the changes you’ve made in Notepad and select the “All files” as its file type, and then name it “CacheClearTWC.bat”.
• Next, go to the location where you saved the file using File Explorer and then run it. This will run a couple of batch scripts which will clear the cache of multiple processes in the system.
• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option to open PowerShell as admin.
• Next, execute this command in the command line: Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “appxmetadataappxbundlemanifest.xml”)}
• After the command has been executed, this will reinstall the Shell Experience components and should fix the problem with the taskbar.

Option 4 – Update, uninstall or rollback the Graphics card drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in MSC into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.
