You can save a copy of a VM, then erase the VM's virtual hard disk after use, replacing it with a fresh copy next time you want to run it, but particularly if you use a SSD drive, at least theoretically you could leave some small bit of data behind. You can create a boot CD/DVD that loads a modified copy of Windows to a RAM disk - a USB stick will work, but you cannot write to a closed CD/DVD so there's no possibility of anything being left over - or in Windows you could copy the virtual hard disk storing a VM to a Ram disk & run it from there. Most use a RAM disk to accomplish that - think virtual hard disk created entirely in RAM. Nothing against Privacy Eraser Pro, CCleaner etc., *from a more purist standpoint*, AFAIK the only way to not leave tracks on your device is to run the OS in volatile RAM, so everything's gone when it's turned off. I mean I am just buying a program to erase some data not MS Office that I can use hundreds of different ways. Sorry developers that price is just a little to steep for me. I do know that I would not pay $80 for this program. I do not know if I will keep this program or not. Then click on that and you can add everything. For anyone else who is looking for this click on Help and you will see Upgrade to Pro. One of my problems after starting this program was where to put the registration code. I don't know but just beware that you will lose everything when you Erase everything.

Maybe there is something different in how browsers are changed. So I opened the program back up and yes sessions & site preferences were unchecked. Maybe I did not actually uncheck the box. I am wondering why these two things were changed that were suppose to be left alone. I did go in and unchecked the boxes for sessions & site preference. Upon opening Firefox (my preferred and favorite browser) I noticed that all my pinned tabs were gone. I restarted my computer and started my regular running programs again. it found less than 20 kb of data that needed removing. Well I let Privacy Eraser do its thing and when finished I ran CCleaner again. Not being a techie person I was amazed that Privacy Eraser found so much more. CCleaner found a little over 500 MB, Privacy Eraser found over 800 MB. I ran both cleaners side by side to see what each found. I do not honestly believe they will erase/remove everything so hackers will not still some tidbit of information. For any of these cleaners/erasers I only use them to help save time clearing stuff. With the Pro version of Privacy Eraser being featured I thought I would try it.
