Methods to prevent normal updates after Toshiba Windows Update fails.

　1. Windows will place temporary files in C when performing an update operation :/WUTemp folder, find the folder and manually install the patch file inside. After the installation is complete, use Windows Update again to update. If the problem still cannot be solved, delete the WUTemp folder.

2. You need to delete the Wuhistv3.log file in the \Program Files\WindowsUpdate folder in the system installation partition (this file records the history of Windows Update installation), and then use Windows Update again to update.
