IMO, it would be better to reset the computer to factory or remove the hard drive. you can still donate the computer without a hard drive. They can add one as needed.
the problem with just deleting files is they could anywhere on the computer and it would be too easy to miss one. finally you might be able to access the computer by going through safemode if you have the user name and password.
I'm giving my husband's computer to Goodwill. He passed on in 2017 and it's just been sitting there. Now that it's going to be re-homed I want to make sure there are no important files in it to compromise my security. However I can't gain access to any files. The usual Windows screen comes up with the date and time, which are bouncing up and down, and there is no prompt to log in at all. Obviously I don't want to pay someone to get into it since I'm giving it away. What do you think I should do?
