في Windows
log4j2-scan [--fix] target_path

java -jar logpresso-log4j2-scan-3.0.1.jar [--fix] target_path
إذا أضفت خيار --fix، فسوف ينسخ هذا البرنامج ملف JAR الأصلي المعرض للثغرة إلى ملف .bak، وينشئ ملف JAR جديدًا بدون إدخال org/apache/logging/log4j/core/lookup/JndiLookup.class. يتم أرشفة جميع ملفات .bak في ملف zip واحد باسم log4j2_scan_backup_yyyyMMdd_HHmmss.zip، ثم حذفها بأمان. في معظم البيئات، لن يتم استخدام ميزة بحث JNDI. ومع ذلك، يجب عليك استخدام هذا الخيار على مسؤوليتك الخاصة. يمكنك بسهولة استعادة ملفات JAR الأصلية المعرضة للثغرة باستخدام خيار --restore.
