Windows files are often attacked by malware that prevents them from working properly. The first step in solving problems with or other Windows system files should be to scan your system for malware using an antivirus tool.

If you do not have anti-virus software installed on your system, you should do this immediately. An unprotected system is not only a source of file errors, but more importantly, it makes your system vulnerable to many threats.

  • Keep the command prompt window open until the command is completed.
