1. Mount the .ISO file by double clicking on it.
2. Open 'Windows Powershell' or 'Command Prompt' with Admin privileges (right click -> Run as Administrator)
3. Let's check the System Health first, by running these commands:
3.1 dism /online /cleanup-p_w_picpath /scanhealth
3.2 dism /online /cleanup-p_w_picpath /checkhealth
3.3 dism /online /cleanup-p_w_picpath /restorehealth
4. I'm sure that 3.3 will give you an error stating that it could not perform the task. And now it's when the mounted ISO comes into play. Let's specify the file from the ISO so that we can fix it. Run the following command: (Notice that X must be the drive letter on which your system has mounted the ISO)
4.1 DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:\Sources\Install.wim:1 /LimitAccess
5. Now let's repair any damage in the system files, shall we?
5.1 sfc /scannow
1.掛載.iso文件，雙擊就可以了。
2.打開“Windows PowerShell中”或“命令提示符”以管理員權限（右鍵 - >以管理員身份運行）
3.讓我們來看看系統健康，通過運行以下命令：
3.1 dism /online /cleanup-p_w_picpath /scanhealth
3.2 dism /online /cleanup-p_w_picpath /checkhealth
3.3 dism /online /cleanup-p_w_picpath /restorehealth
4.我敢肯定，3.3將會給你一個錯誤，指出它不能完成的任務。而現在它的時候，安裝ISO進場。讓我們指定的ISO文件，這樣我們就可以解決這個問題。運行以下命令：（注意，X必須是在其上你的系統已經安裝在ISO的驅動器盤符）
4.1 DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:\Sources\Install.wim:1 /LimitAccess
5.現在讓我們來修復系統文件損壞，好嗎？
5.1 SFC/ SCANNOW
