Solution Steps
- 1 First, try clearing the Windows Update cache. Press Windows+R, type 'services.msc', and press Enter. Find 'Windows Update', right-click, and select 'Stop'.
- 2 Open File Explorer and navigate to C:\Windows\SoftwareDistribution. Delete all the contents of this folder (you can select all and press Shift+Delete). This forces Windows to download updates from scratch.
- 3 Restart the Windows Update service by going back to Services, right-clicking 'Windows Update', and selecting 'Start'.
- 4 Try Windows Update again. Press Windows+I, go to 'Windows Update', and click 'Check for updates'.
- 5 If the error persists, you may need to reset the Windows Update components using the same steps as for 0x80240017 (stop services, rename folders, restart services).
- 6 You can also try using the Windows Update Troubleshooter, which can automatically fix conflicts.
