The error occurs when the connected peripheral device, upon removal using the ‘Safe Removal Hardware’ program, hangs up a problem within the process. The error prompt you then see is referred to within the operating system as error code 47.

It usually pops up on your computer screen with the following message:

Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer. (Code 47)

Solution

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.

Option 1 – Try to remove the IIS from Windows Features

The IIS is installed from the Windows Features and you can find it at Control Panel > Programs. From there, uncheck the checkbox for the Internet Information Services. 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.
• After that, start the update process for Windows 10 again.
