How to Fix Windows 10 Update Error Code 80004002

In case you don’t know, there is a built-in tool in Windows 10, known as Reliability Monitor that provides a day-to-day snapshot of the health of your system. It warns users of any looming issues or disasters before your computer breaks down finally. So obviously, Reliability Monitor is useful, however, there are times when it could behave incorrectly. For instance, it might fail to show you any updates even when they are installed. Thus, if you experience any malfunctions with the Reliability Monitor tool in Windows 10, read on as this post will guide you in updating or working in Windows 10. To fix the problem with the Reliability Monitor, there are several fixes you can check out. You can try to enable the data collection for Reliability Monitor or reset it, as well as put your computer in a Clean Boot State. For more information, refer to each one of the options given below.

Option 1 – Try to enable the Data Collection for Reliability Monitor

The Reliability Monitor tool uses data provided by the RAC Agent scheduled task and it will start to display a Stability Index rating and specific event information 24 hours after the system installation. The RACAgent scheduled task, by default, runs after the operating system is installed. And if it is disabled, it must be manually enabled from the Task Scheduler snap-in for MMC or Microsoft Management Console. Thus, you need to enable the Data Collection for Reliability Monitor to fix the problem.

Option 2 – Try to reset the Reliability Monitor

The next thing you can do to fix the issue with the Reliability Monitor might want to reset it to resolve the problem. If the Reliability Monitor is already open, you have to close it and open it again. After the reset is done, it may take up to 24 hours for the Reliability Monitor to display results again. This should fix the problem.

Option 3 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. 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” check box 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” check box.
• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

As you know, Windows operating system comes with tons of features. Some of which are not intended to be used by normal customers or users directly which means that only a small percentage of the huge user base of the operating system leverages the use of such features. However, they’ve added some major value to the feature list of the operating system. You can find these features under the “Turn Windows Features on and off” option. This indicates that if you want to, you can just type in “Turn Windows Features on and off” in the search box and then enable any feature that you want to enable. Aside from that, there are other ways you can disable or enable the optional Windows Features in your Windows 10 computer.

Option 1 – via Control Panel

• Open Control Panel and select Uninstall a Program.
• After that, select the “Turn Windows features On or Off” option on the left side.

Option 2 – via Command Prompt

• Tap the Win + X combination on your keyboard or right-click on the Start button and then click on Command Prompt (Admin). Alternatively, you can also type “cmd” in the Cortana search box and right-click on the Command Prompt icon, and select the “Run as administrator” option.
• If a User Account Control or UAC prompt appears, click on Yes.
• Next, type in the following command to see the list of the available features.

DISM /online /get-features /format:table | more

• Now all you have to do is copy the name of the feature that you want to enable and for you to do that, you need to execute the following command:

DISM /online /enable-feature /featurename:[Enter the name of the feature here] –All

Note: Now if you want to disable a feature that’s already enabled in your computer, refer to these sub-steps:

• First, you need to check what features are enabled, and for you to find out, enter this command: DISM /online /get-features /format:table | find “Enabled" | more
• And if you want to check the detailed information about a particular feature, you can enter this command: DISM /online /get-featureinfo/featurename:[Enter the name of the feature here]

Option 3 – via Windows Powershell

As you know, the Windows Powershell is a very important tool in Windows 10, and a powerful one at that since you can do a lot of things using this command line. So while you use this tool you need to populate the list of available features first and then you have to download the feature your desired feature.

• Search for PowerShell in the Cortana search box and then run it with administrator privileges.
• Next, type in the following command to populate the list of available features:

Get-WindowsOptionalFeature –Online

• After that, enter the following command to install any feature you want to enable from the list of available features:

Get-WindowsOptionalFeature -Online -FeatureName *Type feature name*

• Now enter the following command to enable your desired feature:

Enable-WindowsOptionalFeature -Online -FeatureName “Type feature name” –all

• And if you want to disable any enabled feature, just enter the following command:

Disable-WindowsOptionalFeature -Online -FeatureName “Type feature name”

Option 4 – via an external installation source

You also have the option to fetch the latest features from an updated offline source. The source could be an ISO any other type of image or just a folder. So you need to decide if you want to use Windows Powershell or Command Prompt.

• If you want to use Command Prompt, just enter this command: exe /online /enable-feature /featurename:< /All /Source:<Enter the path of the feature here>
• If you want to use Windows Powershell, use this command: Install-WindowsFeature –Source “<Enter the path of the feature here>”

Note: If you want to get the latest features, you need to get the latest version of the image of the operating system that you are trying to install the feature from.

If, while using your computer, you encounter the ACPI.sys Blue Screen error, read on as this post will guide you in fixing the problem. The ACPI.sys file is a Windows operating system file that is related to the MSDN 2939. ACPI.sys, the Windows ACPI driver, is an inbox component of the Windows operating system. It is the one that supports the power management as well as the Plug and Play or PnP device enumeration. And so if this file ends up getting corrupted, it is known to cause a Blue Screen error. Another possible cause for the ACPI.sys Blue Screen error includes RAM issues, incompatible firmware, hard disk issues, corrupted drivers or malware infection, and so on. Here are some Blue Screen errors that can be triggered by the ACPI.sys file:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• SYSTEM THREAD EXCEPTION NOT HANDLED
• IRQL NOT LESS OR EQUAL
• KERNEL DATA INPAGE
• SYSTEM SERVICE EXCEPTION

To fix the Blue Screen error associated with the ACPI.sys file, refer to the instructions provided below.

Option 1 – Try to recreate the ACPI.sys file

If the first option didn’t work, the next thing you can do is to recreate the ACPI.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. This 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 ACPI.sys and rename it to ACPI.old.

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

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

Option 2 – Try to update or rollback the ACPI Driver

The first thing you can try to fix the Storport.sys Blue Screen error is 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.

• Tap the Win + X keys to open the Win X menu and from there, select the Device Manager.
• After opening the Device Manager, look for the ACPI.sys driver and right-click on it, and then select Properties.
• Next, go to the Driver section. Note that the rollback option would only be available if you’ve recently updated the ACPI.sys driver. So if you can’t see it then click on the Update Driver button.
• After that, Windows will automatically check for the problems that could be related to the Blue Screen error.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver. On the other hand, if updating the ACPI driver, didn’t work, you can also try to copy the ACPI.sys system driver file from the System32 folder of another computer that’s functioning properly and runs the same Windows OS version. Afterward, place it on your problematic computer and check if it fixes the BSOD error or not.

Option 3 – Run System File Checker or SFC scan

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 with good system files. 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

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, 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.

Option 5 – Run System Restore

• 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.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
