This utility offers a one-stop-shop for cleaning and maintaining your computer for better overall system performance. The interface is very simple, featuring only a few buttons, which makes it easy to get down to cleaning immediately (in fact, it automatically runs on start-up) and doesn't confuse you with multiple steps.The Maintain Windows section focuses on four areas of maintenance: spyware removal, Registry cleaning, a privacy sweep, and deletion of junk files.The Diagnose System button provides system optimization tools, detects spyware, defragments your disk, and scans for hijacked Windows settings. In our tests the scan and clean for each of these areas took less than 10 minutes to complete. In many of these scans, it is difficult to tell what exactly is being accomplished by some of the tools, but we were able to test against other trusted apps, which confirmed Advanced SystemCare's efficacy in those areas.
