They take up a lot of disk space, maybe 30 GB or more, and they could contain private information, so there is an option to erase them. Windows 10 is updated twice a year with a new version and backups and files from the previous version still on the disk drive. Windows generates thumbnails of all the image files on the disk drive and even after deleting an image, its thumbnail may still be stored by Windows. You are first asked if you are a basic or advanced user and if you choose advanced, you get to configure everything and there are quite a lot of settings you can adjust, so I won’t ist them all, but here are some of them. Unlike some privacy clean-up tools that just present clean-up options with little explanation, this one starts with a series of questions and these are important for setting the default clean-up actions. PrivaZer is intelligent and it will avoid erasing anything that might be useful, unless you override its settings and tell it to. However, the basic free version is good enough for me. There is a ‘Donor’ version and after donating to the author any amount you want from $10 or £10 up, you have access to a few more features. I prefer not to install software if I can help it. Go to the Download page and there is a portable version that can be run from the Downloads folder on the computer with no installation.

PrivaZer is a free Windows utility that does all of this and more, and it cleans more than the average privacy cleaner. Browser cookies in which websites store information, programs you have run in Windows, recent files opened in various programs, program caches, system logs, Windows updates and so on

These include your web browsing history, which is a list of all the websites you have visited over the last month or two. A privacy utility is one that erases your internet tracks and general computer activities.
