Running the Windows Update service does not always go well as from time to time, you could encounter some errors when using it. One of these errors is the Windows Update Error 0xc1900403. In such cases, you will see the following error message under the Windows Update section:

“There were problems installing some updates, but we’ll try again later, If you keep seeing this and want to search the web or contact support for information, this may help – 0xc1900403”

The log files displayed in the error message may include, “0XC1900403 – MOSETUP_E_UA_CORRUPT_PAYLOAD_FILES”. This indicates that the payload files are corrupted which is why you’re getting the Windows Update Error 0xc1900403 and to fix it, you can try to restart your computer and install the updates again or reset the Windows Update-related folders. You could also run the Windows Update troubleshooter or use either the Standalone Installer or the Media Creation tool. For more details, refer to each one of the options provided 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 0x80240034. There are cases where the issue resolves on its own as it could just be some simple network or PC error.

Option 2 – Delete the contents in the Software Distribution folder and Catroot2 folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

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 3 – Try running the Windows Update troubleshooter

You might also want to run the Windows Update Troubleshooter as it could also help in fixing Windows Update Error 0xc1900403. 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.

As of the time of writing this article you no longer need or are required to have a password if you plan to log in to your Microsoft account. Microsoft explored various options for account security and came to the conclusion that passwords are obsolete. Microsoft is letting you access your account through the Microsoft Authenticator app, Windows Hello, a security key, SMS verification, or email verification code. All of these methods are way better in terms of security than passwords.

How to turn these features on?

To get rid of your Microsoft password, the process is simple. You simply need to go to your Microsoft account, click “advanced security options,” then “enable passwordless accounts” under the Additional security section.

If you are running the Windows Update service but decided to stop it but you encountered an error message instead that says, “The Windows Update service could not be stopped”, read on as this post will help you fix the problem. This kind of error appears when you use the Command Prompt to stop the Windows Update service, especially if you are using cmd without admin privileges. A lot of users reported that they were not able to disable the automatic Windows Update in Windows 10 using Command Prompt. The command used to stop the Windows Update service is the “net stop wuauserv” command. However, when some users executed this command, they got the error message. So if you are one of these users that can’t stop the Windows Update Service via Command Prompt, you can try to fix that using PID as well as checking the Service dependencies. For more details, follow the given options below.

Option 1 – Try to stop the Windows Update service via PID

In case you don’t know, each running service or process has its own unique ID or PID and you can find it in the Task Manager. You can use it to stop the Windows Update service. How? Refer to these steps:

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Services tab and look for the service named “wuauserv” and get its PID.
• After that, type “cmd” in the Windows Start search and right-click on Command Prompt from the search results and then select the “Run as administrator” option.
• After opening Command Prompt with admin privileges, execute this command: taskkill /f /pid <PID>

Note: You need to replace “<PID>” with the PID of the “wuauserv” service. For instance, the PID is 6676, then this is how the command should be “taskkill /f /pid 6676”.

• After you execute the command, you will this message on your screen, “SUCCESS: The process with PID 6676 has been terminated” which indicates that you have stopped the Windows Update service successfully.

Option 2 – Try to check the Service dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

There are instances when the Windows 10 installation needs interaction before it reaches the file process. And so if you suddenly encounter the Windows Update Installation Failure 0x80240020 error under the Windows Update History, then you need to get it fixed. When you encounter this kind of Windows Update Error, you will see an error message that says, “The operation did not complete because there is no logged-on interactive user”. This error also indicates the “WU_E_NO_INTERACTIVE_USER” code. To resolve this issue, in this post we’ll walk you through a couple of steps but before you get started, know that you don’t have to run any troubleshooter or delete any file just to fix this error since all you have to do is enable one option that can automatically login with your account and complete the installation for you. With that said, just make sure to only try running Windows Update once you’re told to do so. There are two ways you can enable the option that could resolve the Windows Update Installation Failure 0x80240020 error. One is via Settings while the second one is via Registry Editor.

Option 1 – via Settings

Step 1: Go to Settings > Accounts > Sign-in Options. Step 2: From there, toggle on the “Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart” option. Step 3: After that, it will make sure that the interaction part is removed from the Windows Update process. Note: If your device is joined in a domain or if some work or email policies are applied to your device by your company or organization, then you wouldn’t be able to see this option in Settings and that’s where the Registry Editor comes in. Just make sure that you’re logged in as an administrator and that you create a System Restore Point first since registry hacks are sensitive and could highly impact how your computer behaves or functions. Once you have that covered, follow the steps below.

Option 2 – via Registry Editor

Step 1: In the Start search, type “Regedit” and hit Enter to open the Registry Editor. Step 2: Navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade

Note: If the above-given registry key does not exist, you can simply create it. All you have to do is right-click on the WindowsUpdate key and then select the New Key option and type “OSUpgrade” as its name. Afterward, create a new DWORD (32-bit) Value and name it “AllowOSUpgrade” and set its value to 0x00000001. Step 3: Restart your computer and check if the error is now fixed. And then try to update your Windows 10 computer again and while you’re at it, make sure that you’re around your computer to interact with the prompts needed to complete the installation process.

It could be caused by an incomplete installation or uninstallation of some applications or program, or it could also be caused by some exploit that intervenes with the normal functioning of the computer, as well as bad sectors on the hard disk, damaged system files, malfunctioned system drivers, modified Windows Registry files, or a Blue Screen occurrence during a Windows Update and many more. Getting this bug check means that a single-bit error was found on this page. It also indicates that this is a hardware memory error and to resolve it, you need to follow the suggestions laid out below but before that, it is recommended for you to create a System Restore Point first so that if anything goes wrong, you can always go back to the previous state.

Option 1 – Run a Memory Check to test RAM

Since the problem might have something to do with hardware memory, you need to test RAM by running a Memory Check using the Windows Memory Diagnostic. Refer to these steps to do so.

• Tap the Win + R keys to open the Run dialog box.
• Then type “mdsched.exe” in the field and hit Enter to open the Windows Memory Diagnostic.
• After that, the Windows Memory Diagnostic will give out two options such as:

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.

Option 3 – Check for conflicting or incompatible programs by putting your PC in a Clean Boot state

As mentioned, the FAULTY_HARDWARE_CORRUPTED_PAGE Blue Screen error might be caused by some problematic programs that clash with your existing operating system. Several users reported that numerous programs that are supposedly designed to enhance computer performance are causing conflict in the system instead. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• 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.

• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 4 – Update or rollback drivers

If the first few options 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.

Due to its hybrid core technology, the Alder Lake line of processors had some DRM issues with some game titles where DRM protection software detected hybrid core design switching via manager as a hack attempt and prevented the game from working properly. Over 50 titles were affected by this issue, now only 3 remain still affected but it is being worked on them so that can be also resolved. Intel says that the remedy to the issue for these games is the scroll lock fix which can be done so by enabling Legacy Game Compatibility mode from the BIOS of your motherboard. When running the said games, you can press scroll lock to park the E-cores on Intel's Alder Lake Desktop CPUs to get rid of DRM issues. Certain motherboard manufacturers such as MSI and Gigabyte have made this even easier through software tools with which you don't have to access the BIOS. All you need to do is select a button in the tool which works on both Windows 11 and Windows 10 operating systems and you will enable compatibility mode.
