我运行了sfc / scannow，它修复了一些文件，但未能修复这些文件：
Cannot repair member file [l:20{10}]"dwmapi.dll"
Cannot repair member file [l:22{11}]"dwmcore.dll"
Cannot repair member file [l:20{10}]"dwmapi.dll"
Cannot repair member file [l:22{11}]"dwmcore.dll"
Cannot repair member file [l:18{9}]"duser.dll"
Cannot repair member file [l:18{9}]"duser.dll"
Cannot repair member file [l:14{7}]"sfc.exe"
Cannot repair member file [l:14{7}]"sfc.exe"
Cannot repair member file [l:20{10}]"dwmapi.dll"
Cannot repair member file [l:22{11}]"dwmcore.dll"
Cannot repair member file [l:18{9}]"duser.dll"
Cannot repair member file [l:14{7}]"sfc.exe"
Cannot repair member file [l:18{9}]"duser.dll"
Cannot repair member file [l:14{7}]"sfc.exe"
Cannot repair member file [l:20{10}]"dwmapi.dll"
Cannot repair member file [l:22{11}]"dwmcore.dll"
是否可以轻松地修复它们（无需重新安装Windows）？
