Wise Disk Cleaner Pro is a quick and safe junk file cleaner. With the advanced scan engine, it safely and quickly locates junk files in your system. By deleting temporary and junk files, it increases available disk space and improves system performance. You can specify the content to include or exclude in the scan and select drives to scan. Its Disk Scrubber enables you to permanently wipe deleted files and secure your privacy from prying eyes. And its Deleted file Recovery tool can effectively recover deleted files.
The older your PC is, the more junked-up its Registry becomes. Badly written programs (and there are plenty of those around) don’t bother to clean the Registry when you uninstall them, and some programs add unnecessary junk to the Registry. The more junked-up your Registry, the more likely it is to crash or to slow down your PC. Do you need a Reliable Registry Cleaner? Then Wise Registry Cleaner is all you need! It is one of the safest Registry cleaning tools available in the market today. Its scanning engine is thorough, safe and fast. Wise Registry Cleaner Professional was designed to improve your PC performance by system optimization.
