Once you are in safe mode, you can try to install your antivirus application without the hindrance of malicious software. Now, you are able to run the antivirus scan to remove computer viruses and malware without hindrance from another malicious application.

Download the security software in an alternate browser

Malicious code may exploit vulnerabilities in a particular internet browser and block access to all anti-malware software sites.

Run antivirus from a pen drive

Could not configure one or more components
If you are trying to install or upgrade your Windows 10 computer but suddenly encountered an error message saying, “Windows could not configure one or more system components”, read on as this post will show you how you can fix the problem. You are not alone in experiencing this problem as other users also reported having the same scenario. Some of them reported getting the following error message:
“Windows could not configure one or more system components. To install Windows restart the computer with error code 0xc1900101-0x30018.”
When you check on the Windows 10 rollback log, you will see a part with the “iisetup.exe” that’s related to the abort. Usually, the upgrade process completes over 50% and gets stuck and then rolls back later on and generates the error logs. This kind of error, in most cases, appears during the upgrade of Windows 10 and is related with the Internet Information Services or IIS in Windows 10. For some unknown reason, it restricts the installation or the upgrade which causes the error to appear. To fix the “Windows could not configure one or more system components” error, you can try to remove the IIS from the Windows Features or rename the “inetsrv” folder. You could also move all the folders related to IIS to another drive. For more details, refer to the options provided below.

Once done, click on the OK button to save the changes. Note that this process will get rid of all the related programs, services, and folders from Windows 10. So if you want to, you can just install them later on or use an offline installer from the official site of Microsoft.

Option 2 – Try renaming the inetsrv folder

The next option you can check out to resolve the problem is to rename the “inetsrv” folder. If you have uninstalled IIS from the Windows Features, this should remove the folders as well, however, it didn’t remove the folder then you have to delete the folders that are related to the IIS by following these steps:
  • First, you have to boot into the Advanced Recovery Mode and from there, open Command Prompt.
  • Next, execute this command to rename the folder from this location, C:Windowssystem32inetsrv: rename C:/Windows/system32/inetsrv/inetsrv.old
  • Once done, boot into your computer normally and try to upgrade Windows 10 again, and check if the problem is fixed or not.

Option 3 – Try to move the folders related to IIS to a different drive

  • Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
  • Next, look for the Application Host Helper Service from the list of services and stop it.
  • Once done, take ownership of the “WinSxS” folder and then move the *windows-iis*.*” folders to another drive. You can just search using the “*windows-iis*.*” keyword in the Start Search.
  • Next, tap the Ctrl + X keys and paste the folders to another drive.

  • Now restart your computer to successfully apply the changes made.

Option 2 – Try to update the Network drivers

If the present Network driver is giving you a headache that is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error, then you need to update the Network drivers. To do so, here’s what you have to do:
  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
  • Then right-click on each one of the Network drivers and update them all.
  • Restart your PC and see if it helped in fixing the BSOD error.
Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 3 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Netwtw04.sys failed BSOD error. 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 to 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
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 4 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:
  • Open the Command Prompt as admin.
  • Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
  • The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the CHKDSK Utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.
  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the following command and hit Enter:
chkdsk /f /r
  • Wait for the process to be completed and then restart your computer.
