The past couple of days whenever I booted up I was getting a notification telling me I needed to backup my file encryption key. It turned out that this was being caused by a file I had downloaded.
If you are getting this notification, its fairly simple to fix, if not immediately obvious. You need to find the files or folders which are encrypted. You can do this by using the following procedure:
1) Type “Command Prompt” in the search box and right click to run as Administrator.
2) Type the following command:
It will then list any encrypted folders and files that are on your system.
3) You can then move to the encrypted folders that are listed.
These files should be showing up as green in your explorer window.
You can then right click on the object and choose properties. You may find that there is a button telling you that the file is blocked. Click on this button, then apply and then on advanced. You then need to untick the “encrypt contents to secure data” box and OK out. You should now stop getting the prompt.
