<p><b>System File Checker</b> (<b>SFC</b><sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>) is a utility in <a href="Microsoft_Windows" title="Microsoft Windows">Microsoft Windows</a> that allows users to scan for and restore corrupted Windows system files.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading2"><h2 id="Overview">Overview</h2></div>

<p>Microsoft ships this utility with <a href="Windows_98" title="Windows 98">Windows 98</a>, <a href="Windows_2000" title="Windows 2000">Windows 2000</a> and all subsequent versions of the <a href="Windows_NT" title="Windows NT">Windows NT</a> family of operating systems. In <a href="Windows_Vista" title="Windows Vista">Windows Vista</a>, <a href="Windows_7" title="Windows 7">Windows 7</a> and <a href="Windows_10" title="Windows 10">Windows 10</a>, System File Checker is integrated with <a href="Windows_Resource_Protection" title="Windows Resource Protection">Windows Resource Protection</a> (WRP), which protects <a href="Windows_Registry" title="Windows Registry">registry</a> keys and folders as well as critical system files. Under Windows Vista, <code>sfc.exe</code> can be used to check specific folder paths, including the Windows folder and the boot folder.

</p><p><a href="Windows_File_Protection" title="Windows File Protection">Windows File Protection</a> (WFP) works by registering for notification of file changes in <a href="Winlogon" title="Winlogon">Winlogon</a>. If any changes are detected to a protected system file, the modified file is restored from a cached copy located in a compressed folder at <code>%WinDir%\System32\dllcache</code>.

</p><p><a href="Windows_Resource_Protection" title="Windows Resource Protection">Windows Resource Protection</a> (WRP) works by setting discretionary access-control lists (DACLs) and <a href="Access_control_list" class="mw-redirect" title="Access control list">access control lists</a> (ACLs) defined for protected resources. If any changes are detected to a protected system file, the modified file is restored from a cached copy located in a folder at <code>%WinDir%\WinSxS\Backup</code>.<sup id="cite_ref-:0_3-0" class="reference"><a href="#cite_note-:0-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Permission for full access to modify WRP-protected resources is restricted to the processes using the <i>Windows Modules Installer service</i> (<code>TrustedInstaller.exe</code>). Administrators no longer have full rights to system files.

</p>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<p>Due to problems with Windows applications being able to overwrite system files in <a href="Windows_95" title="Windows 95">Windows 95</a>, Microsoft has since implemented a number of security measures to protect system files from malicious attacks, corruptions, or problems such as <a href="DLL_hell" title="DLL hell">DLL Hell</a>.

</p><p>System File Checker was first introduced on <a href="Windows_98" title="Windows 98">Windows 98</a> as a GUI utility. It offered scanning and restoration of corrupted system files by matching the version number against a database containing the original version number of the files in a fresh Windows 98 installation. This method of file protection was basic. It determined system files by <a href="File_extension" class="mw-redirect" title="File extension">file extension</a> and <a href="File_path" class="mw-redirect" title="File path">file path</a>. It was able to restore files from the installation media or a source specified by the user. Windows 98 did not offer real-time system file protection beyond <a href="File_attribute" title="File attribute">file attributes</a>; therefore, no preventive or reactive measure was available.

</p><p>All Windows NT-based operating systems since <a href="Windows_2000" title="Windows 2000">Windows 2000</a> introduced real-time file protection, called Windows File Protection (WFP).<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>

</p><p>In addition, the System File Checker utility (<code>sfc.exe</code>) was reimplemented as a more robust command-line utility that integrated with WFP. Unlike the Windows 98 SFC utility, the new utility forces a scan of protected system files using Windows File Protection and allows the immediate silent restoration of system files from the <i>DLLCache</i> folder or installation media.

</p><p>SFC did not appear on <a href="Windows_Me" title="Windows Me">Windows Me</a>,<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> as it was replaced with <a href="System_File_Protection" class="mw-redirect" title="System File Protection">System File Protection</a> (SFP).<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> Similar to WFP, SFP offered real-time protection.

</p>

<div class="mw-heading mw-heading2"><h2 id="Issues">Issues</h2></div>

<p>The System File Checker component included with versions of Windows 2000 earlier than Service Pack 4 overrode patches distributed by Microsoft;<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> this was rectified in Windows 2000 Service Pack 4.

</p>

<div class="mw-heading mw-heading2"><h2 id="Usage">Usage</h2></div>

<p>In Windows NT-based operating systems, System File Checker can be invoked via <a href="Cmd.exe" title="Cmd.exe">Windows Command Prompt</a> (with Admin privilege<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>), with the following command:

</p>

<ul><li><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">sfc /scannow</code> (to repair problems)</li>

<li>or <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">sfc /verifyonly</code> (no repair)</li></ul>

<p>If it finds a problem, it will attempt to replace the problematic files from the DLL Cache (<code>%WinDir%\System32\dllcache</code>). If the file is not in the DLL Cache or the DLL Cache is corrupted, the user will be prompted to insert the Windows installation media or provide the network installation path. System File Checker determines the Windows installation source path from the registry values <code>SourcePath</code> and <code>ServicePackSourcePath</code>.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> It may keep prompting for the installation media even if the user supplies it if these values are not correctly set.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup>

</p><p>In Windows Vista and onwards, files are protected using <a href="Access_control_list" class="mw-redirect" title="Access control list">access control lists</a> (ACLs), and if it finds a problem, it will attempt to replace the problematic files from the Windows Side-by-side Backup (<code>%WinDir%\WinSxS\Backup</code>).<sup id="cite_ref-:0_3-1" class="reference"><a href="#cite_note-:0-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> However, the above command has not changed.

</p><p>System File Checker in Windows Vista and later Windows operating systems can scan specified files. Also, scans can be performed against an offline Windows installation folder to replace corrupt files, in case the Windows installation is not bootable. For performing offline scans, System File Checker must be run from another working installation of Windows Vista or a later operating system or from the Windows setup DVD<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> or a recovery drive which gives access to the <a href="Windows_Recovery_Environment" class="mw-redirect" title="Windows Recovery Environment">Windows Recovery Environment</a>.

</p><p>In cases where the component store is corrupted, the "System Update Readiness tool" (CheckSUR) can be installed on Windows 7, Windows Vista, Windows Server 2008 R2 or Windows Server 2008, replaced by "<a href="Deployment_Image_Service_and_Management_Tool" class="mw-redirect" title="Deployment Image Service and Management Tool">Deployment Image Service and Management Tool</a>" (DISM) for Windows 10, Windows 8.1, Windows 8, Windows Server 2012 R2 or Windows Server 2012. This tool checks the store against its own payload and repairs the corruptions that it detects by downloading required files through Windows update.<sup id="cite_ref-12" class="reference"><a href="#cite_note-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup>
