    Hello Arush47 

     

    Please run the below commands in CMD. Ensure you run CMD as an admin. These commands will delete the Windows Update registry log on your machine and then next time you click on check for updates, WU will check against the entire WU database.

     

    Reg delete HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate

    yes

     

    Net stop wuauserv >NUL

     

    Cd C:\windows

     

    rmdir softwaredistribution /s /q

     

    Net start wuauserv >NUL

     

    I am sure this will help. Let me know how you get on.

     

    Thanks,

    Jose

        You can try these methods to troubleshoot your Windows 10 update issue:

        Method 1: Run SFC Scan.

        To run an SFC scan, follow these steps:

        Run Command Prompt as Administrator.

        Type sfc /scannow and hit Enter.

        This will check and run an auto-repair on the issue.

        Method 2: Run DISM Tool.

        After running the SFC scan and the issue still persist, run the DISM to check the system health and to try restoring the files. To run DISM tool, follow these steps:

        Run Command Prompt as Administrator.

        Type the following commands:

        DISM.exe /Online /Cleanup-image /scanhealth

        DISM.exe /Online /Cleanup-image /Restorehealth

        NOTE: This might a while to finish scanning. Do not cancel.

        Method 3:

        After doing Method 1 and Method 2 but the issue still persist, you can manually reset the Windows Update Components and Run Windows Update process again.

        Resetting Windows Update Components will fix those corrupted Components and will help the Update installation quickly. To reset Windows Update Components, follow these steps:

        Run Command Prompt as Administrator

        Stop BITS, Cryptographic, MSI Installer and Windows Update Services. To do this, type the following commands:

        Net stop wuauserv

        Net stop cryptSvc

        Net stop bits

        Net stop msiserver

        Rename SoftwareDistribution and Catroot2 folder. To do this, type the following commands:

        Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

        Ren C:\Windows\System32\catroot2 Catroot2.old

        Restart BITS, Cryptographic, MSI Installer and Windows Update Services. To do this, type the following commands:

        Net start wuauserv

        Net start cryptSvc

        Net start bits

        Net start msiserver

        Restart your computer and try to install Windows Update.

        Let us know how it goes.

    All i know:
    Run the Windows Update Troubleshooter: Windows includes a built-in tool for detecting and resolving typical Windows Update errors. To access it, go to Settings > Update & Security > Troubleshoot > Windows Update, and then select the "Run the troubleshooter" button.

    Clear the Windows Update cache: Sometimes, corrupt Windows Update cache files can prevent updates from downloading and installing correctly. To clear the cache, open the Command Prompt as an administrator, and then type "net stop wuauserv" followed by "net stop cryptSvc" and "net stop bits". Then, navigate to the "C:\Windows\SoftwareDistribution" folder and rename the "Download" folder to "Download.old". Finally, return to the Command Prompt and type "net start wuauserv", "net start cryptSvc", and "net start bits" to restart the necessary services.

    Check for available disk space: Windows updates require a certain amount of free space on your hard drive to install properly. Ensure that you have enough free space on your system drive (usually C:) to accommodate the update.

    Disable security software temporarily: Sometimes, third-party security software can interfere with the update process. Try disabling your antivirus or firewall temporarily and then attempt to run Windows Update again.

    Just change the Name of the Software Distribution Folder, which is a crucial component of Windows that houses the files necessary for Windows updates. Managed quietly by the Windows Update Agent in the background, this folder occasionally might block new updates from installing.

    This issue often arises when there's a mismatch between the Windows Datastore folder and the Download folder.
