The System File Checker (sfc.exe) is a useful tool that lets you scan the integrity of Windows system files and repair corrupt or missing system files. Numerous cases have been resolved by running the sfc.exe \/scannow<\/code> command.<\/p>\n

However, there are situations wherein a corrupt or missing system file prevents Windows from booting normally or prevents Command Prompt and console programs like Sfc.exe from being launched. In such cases, Sfc.exe can be run offline via the Windows Recovery Environment (Windows RE) in all versions of Windows, including Windows 11.<\/p>\n

Run the System File Checker (Sfc.exe) Offline<\/h2>\n

Step 1: Booting into Windows Recovery Environment<\/h3>\n

Instructions for Windows 8, 10, and 11<\/b><\/p>\n

    \n
  1. Right-click Start, click Shut down or sign out, press and hold the Shift<\/strong> key and click Restart. In Windows 10, you can also open Settings (WinKey + i), click Update and Security, click Recovery, and click the Restart Now button under Advanced startup.\n
    If Windows doesn’t start<\/u>, then boot the system using the installation media or Recovery drive to access the Recovery Environment. In the Windows setup page that appears when booting using the Windows installation media, click Next and click Repair your computer<\/b>.<\/em><\/div>\n<\/li>\n
  2. Click Troubleshoot
    \n<\/li>\n
  3. Click Advanced options
    \n<\/li>\n
  4. Click Command Prompt
    \n<\/li>\n
  5. Use the BCDEDIT<\/a> command to find the drive letter for your Windows installation, as seen from Windows RE.
    \nMore information     here<\/a>.<\/p>\n
    If Windows is installed in the C:\\<\/code> drive, then it’s usually D:\\<\/code> when seen from Windows RE. But it’s better to check it out using BCDEDIT<\/code>. The drive letter of the Windows\/system volume is displayed next to “osdevice<\/code>“.<\/em><\/div>\n

    (Now, proceed to Step 2 of the tutorial…)<\/em><\/li>\n<\/ol>\n

    Instructions for Windows Vista and 7<\/b><\/p>\n

      \n
    1. Configure the boot order in the BIOS, so the first boot device is your CD\/DVD drive.<\/li>\n
    2. Insert the Windows 7\/Vista Setup DVD and restart the computer.\n
      Alternatively, you may use the Windows 7\/Vista System Repair Disc<\/a> if you have one.<\/em><\/div>\n<\/li>\n
    3. When prompted, press a key to boot from the DVD.<\/li>\n
    4. In the “Install Windows” screen, click Repair your computer.<\/b>
      \n<\/li>\n
    5. Select your Windows installation, and click Next.
      \nMake a note of the drive letter of your Windows 7 installation, as seen from Windows RE<\/b><\/u>. This is the drive letter you want to reference when running Sfc.exe offline.<\/li>\n
    6. Click Command Prompt
      \n
      \n<\/b><\/li>\n<\/ol>\n

      Step 2: Running the System File Checker Offline<\/h3>\n

      To scan the integrity and repair a specific file, use this command:<\/p>\n

      sfc \/scanfile=d:\\windows\\system32\\zipfldr.dll \/offbootdir=d:\\ \/offwindir=d:\\windows<\/b><\/pre>\n
      The above command scans the file zipfldr.dll and replaces it if required.<\/p>\n
      <\/p>\n
      To scan the integrity of all system files<\/u> and repair them, run this command:<\/p>\n
      sfc \/scannow \/offbootdir=d:\\\u00a0 \/offwindir=d:\\windows<\/b><\/pre>\n
      <\/p>\n
      Important:<\/strong> To specify an offline log file<\/strong>, use the \/offlogfile<\/code> argument also.<\/p>\n
      (Thanks to Scott Petrack for the offline log file tip.)<\/em><\/p>\n
      Example:<\/p>\n
      sfc \/scannow \/offbootdir=d:\\\u00a0 \/offwindir=d:\\windows\u00a0 \/offlogfile=d:\\sfcoffline.txt<\/b><\/pre>\n
      In this example, there weren’t any integrity violations. If there were any, they would be displayed on the screen and logged in the offline log file you specified (d:\\sfcoffline.txt<\/code>) above.<\/p>\n","protected":false},"excerpt":{"rendered":"
