Fantastic software. Think of Windows Washer as putting your hard drive in an electronic-washing machine. The software detects and securely deletes any files on your system that is keeping information about you from a session of internet browsing/shopping. The files on their own are pretty useless information about you, but hundreds of them piece together your address, DOB, payment details, everything a hacker needs to either shop online with your Credit Card or sign up for a new credit card leaving you with the bill!!
Windows Washer finds these unimportant files and deletes them with a 'security bleach'. This bleaching places three layers of letters and numbers over the original text so hackers and viruses cannot use the information. It is the same level of security shredding as the U.S's Department of Defense.
My first 'wash' re-couped 700mb of memory space from these files! I was on the internet with over 1000 files of personal information in Cache & Cookie files! I'm so happy with this software I'm happy to give it 5 out of 5.
