最好关闭第三方打补丁功能。 启动管理员模式的命令提示符,输入 Dism /Online /Cleanup-Image /ScanHealth 扫描全部系统文件和系统映像文件是否与官方版一致,时间较长,喝杯茶耐心等待一会。 但如果出现错误提示了,那就需要用 Dism /Online /Cleanup-Image /CheckHealth 检查文件的损坏程度,结果一般有两种:一般性损坏可以修复和情况严重完全无法修复。 是前者的话,可以直接调用 DISM /Online /Cleanup-image /RestoreHealth 然后 a) Press Windows Key + X on the keyboard and then select “Command Prompt (Admin)” from the menu. b) Stop the BITS, Cryptographic, MSI Installer and the Windows Update Services. To do this, type the following commands at a command prompt. Press the “ENTER” key after you type each command. net stop wuauserv net stop cryptSvc net stop bits net stop msiserver c) Now rename the SoftwareDistribution and Catroot2 folder. You can do this by typing the following commands in the Command Prompt. Press the “ENTER” key after you type each command. ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 Catroot2.old 如果以前这样干过,要手工删除了Catroot2.old和SoftwareDistribution.old d) Now, let’s restart the BITS, Cryptographic, MSI Installer and the Windows Update Services. Type the following commands in the Command Prompt for this. Press the ENTER key after you type each command. net start wuauserv net start cryptSvc net start bits net start msiserver 如果还是不行,试试用dism++的更新功能
