Executing System File Checker
Initiating the System File Checker (SFC) scan can effectively identify and repair corrupted system files that may be causing Windows Update error 0x80070490. The SFC tool is a built-in Windows utility designed to check the integrity of all protected system files and replace incorrect versions with the correct Microsoft versions when issues are detected.
To run an SFC scan, follow these steps:
- Open Command Prompt as an administrator.
- Execute the command `sfc /scannow`.
This process may take some time to complete depending on the system's performance. After the scan finishes, it is recommended to restart your computer to guarantee any repairs made take effect. Below is a summary of the steps:
Step | Description |
---|---|
1 | Open Command Prompt as an administrator |
2 | Execute `sfc /scannow` |
3 | Restart computer after scan completion |
If the SFC scan identifies issues but cannot fix them, it may be necessary to follow up with the DISM tool using the command `DISM.exe /Online /Cleanup-image /Restorehealth`. This step will help repair the system image before running the SFC scan again, guaranteeing a thorough resolution to the error code 0x80070490.
Using DISM Tool
When the System File Checker (SFC) scan is unable to resolve the detected issues, utilizing the DISM (Deployment Imaging Service and Management Tool) command can be a more thorough approach to repairing the Windows image and addressing Windows Update error 0x80070490.
The DISM tool is especially effective in correcting deeper system image problems that may prevent Windows updates from installing correctly.
To use the DISM tool, follow these steps:
- Open Command Prompt with administrative privileges: Right-click on the Start menu and select 'Command Prompt (Admin)' to guarantee you have the necessary permissions to run the command.
- Execute the DISM command: Type `DISM.exe /Online /Cleanup-image /Restorehealth` and press Enter. This command will initiate a scan and repair of the system image.
- Be patient: The DISM scan may take some time to complete, depending on the extent of corruption in the system image. Allow the process to finish without interruption.
- Run SFC again: After the DISM tool completes its task, it is advisable to run `sfc /scannow` to address any remaining corrupt system files.
Resetting Windows Update Components
Resetting Windows Update Components is an important step in resolving Windows Update error 0x80070490, as it addresses potential issues within the update infrastructure by halting services and renaming key folders to refresh the update process.
To begin, open Command Prompt with administrator privileges. This is critical as administrative rights are needed to stop the Windows Update services. The primary services to halt are 'wuauserv,' 'cryptSvc,' 'bits,' and 'msiserver.' Stopping these services guarantees no active updates interfere during the reset.
Next, rename the SoftwareDistribution and Catroot2 folders. These folders store temporary update files and can accumulate corrupted files over time, leading to error code 0x80070490. Use the Command Prompt to rename these folders, prompting Windows to recreate them and potentially fix update errors.
After renaming, restart the services previously stopped. This step is significant as it allows the system to resume its update process with fresh components.
Creating a New User Account
Creating a new user account can effectively resolve Windows Update error 0x80070490 by circumventing corrupted settings in the existing profile. This method provides a fresh user profile that may not inherit the issues present in the original account.
Here's how you can create a new user account:
- Navigate to Settings: Open the Start menu and go to Settings > Accounts > Family & other users.
- Add a New User: Select 'Add someone else to this PC'.
- Create a Local Account: Choose 'I don't have this person's sign-in information' and then select 'Add a user without a Microsoft account'.
- Sign In: Log out of your current account and sign in with the newly created user profile to determine if the Windows Update error persists.
If the error is resolved, consider migrating your files and settings from the old account to the new one for continued use.
This method can be a straightforward way to bypass corrupted settings and guarantee system updates proceed smoothly. By creating a new user account, you are fundamentally isolating the error 0x80070490 to potentially avoid further complications.
This approach is often recommended for users seeking a quick and effective solution to Windows Update issues.
