Why is Windows Update stuck downloading?
Windows Update download stuck is usually caused by network problems, corrupt update files, system errors, or background software conflicts. 1. Network problems may cause slow download or interruption. It is recommended to restart the router, use a wired connection, test the network speed and clear the update cache. 2. When the update file or system file is corrupt, you can run Windows Update troubleshooter, use the System File Checker (sfc/scannow) or manually reset the update component. 3. Background programs or antivirus software may interfere with the update process. The relevant software should be temporarily disabled, other applications that occupy resources should be closed, and update in safe mode. 4. Outdated or incompatible drivers may also cause problems. You can update the driver and check the hard one through the device manager or manufacturer's website.
