Password Protect in Windows 7
First post on here, but looking for some help regarding password protection. We have been asked to send off video evidence of a drama project. And asked to password protect it, due to it containing images of students.
However, I have attempted to password protect it using 7zip/winRar but obviously this would require the external PC having one of these programs installed. I just wondered if there is an easier way that doesn't require them to download a piece of software to open. I'm aware this was made extremely difficult when windows 7 was introduced but thanks for any help in advance. :)
