Make your old PC run like new. Keep your new PC running fast and problem-free. System Mechanic improves performance, repairs drive errors, eliminates crashes, manages installed programs, and defends against malware. Without regular tuneups, all computers slow down with use. Junk files clog your system. Fragmented drives, registry clutter, and driver conflicts degrade PC performance, leading to system crashes and freezes. System Mechanic combines over 40 powerful tuneup tools and wizards to speed up your PC and maintain it in peak condition. The world's best-selling PC tune-up software replaces dozens of less powerful utilities, offering total PC care in a single integrated package. System Mechanic runs automatically, intelligently cleaning and tuning your entire PC. Or you can launch select tools in the software whenever you think your system may need a boost. Performance and security features include registry repair; hard drive, memory, and registry defragging; junk file and file fragment clean-up; application management to reduce system overhead; spyware removal and security leak protection; and military-standard file erasure.
