Hello Rice,
Thank you for posting question on Microsoft Windows Forum.
Based on the provided error code 0x80245006 which probably indicates that Windows Update cannot find the required files or that the update components on your device have become corrupted.
Since your device has not updated since September, a specific file from that period likely got "stuck" or corrupted during a download, effectively clogging the pipe for all future updates.
The suggestion here is to clear the "Stuck" Update Cache. We need to stop the update services, rename the folders where updates are stored (forcing Windows to create fresh ones), and then restart the services.
- Open Command Prompt as Administrator. Press Windows Key + S, type cmd. Right-click "Command Prompt" and select Run as administrator. Stop the Update Services. Type the following commands one by one, pressing Enter after each net stop wuauserv , net stop cryptSvc , net stop bits , net stop msiserver .Then rename the Corrupted Folders by typing these two commands ren C:\Windows\SoftwareDistribution SoftwareDistribution.old and ren C:\Windows\System32\catroot2 catroot2.old Restart the above Services by running these commands one by one in order net start wuauserv , net start cryptSvc , net start bits , net start msiserver .Restart your computer and try running Windows Update again. Please note: The first check might take longer than usual.
- In case, the above clearing the cache did not work, the update mechanism itself might be damaged. You can use built-in Windows tools to repair Corrupted System Files. Open Command Prompt as Administrator again. Run the DISM tool to check the health of your Windows image by running this command DISM /Online /Cleanup-Image /RestoreHealth . Then run the SFC tool for scanning for missing files by running this command sfc /scannow .Once both are complete, restart your PC.
Alternatively, you can manually install the latest "Cumulative Update" to get your system back on track. Go to Settings > System > About to see your System Type (usually x64) and Version (e.g., 22H2 or 23H2). Go to the Microsoft Update Catalog. Search for "Windows 11 Cumulative Update 2026" (or Windows 10, depending on your OS). Look for the most recent one (verify the date). Download the update matching your system (x64) and run the .msu file. This will force the update to install without using the broken Windows Update service.
