Sometimes, Windows updates can fail or cause errors on your computer due to corrupted files, incompatible drivers, or malware. To troubleshoot any errors, you should restart your computer and try to install the updates again. You can also run the Windows Update Troubleshooter, a tool that can detect and fix common problems with Windows updates which can be found in your settings under Update & Security > Troubleshoot > Additional troubleshooters > Windows Update. Additionally, you can run a system file check, a command that can scan and repair any damaged or missing system files by opening the Command Prompt as an administrator and typing sfc /scannow and pressing Enter. Finally, you can run a disk cleanup, a tool that can remove any temporary or unnecessary files that might interfere with Windows updates by opening the File Explorer and right-clicking on your C: drive and selecting Properties > Disk Cleanup.
