1. BleachBit
Another bad computing habit: forgetting to maintain your system.

It can also guard your privacy by "shredding" files so that they can't be recovered after deletion. Operating System: Windows, Linux.
2. AxCrypt
Yet another bad habitstoring personal or sensitive data on your system without encrypting itis especially bad if you use a laptop. AxCrypt makes it fast and easy to encrypt files with Windows. Just right-click files or folders in Windows Explorer, and they'll be encrypted automatically. Operating System: Windows.
3. TrueCrypt

You can also use it to encrypt data on a thumb drive so that you can take sensitive information with you without worrying about losing your drive. Operating System: Windows, Linux, OS X.
4. KeePass
The last bad computing habit on our list is bad password selection, as in picking passwords that are easy to guess or using the same password for all of your accounts. KeePass makes it easy to choose different passwords for every login, because it remembers the passwords for you. All you have to remember is the one master password to unlock the encrypted database. Operating System: Windows.
5. PWGen
Have trouble thinking of strong passwords? PWGen thinks of random strings of letters and numbers for you, so that you don't end up choosing something easy to guess, like "123456." Operating System: Windows.

9. FreeMind
The FreeMind mind-mapping software makes it easy to create free-flowing diagrams like you would in a brainstorming session.

Always forgetting things? PNotes lets you leave yourself electronic "sticky notes" on your desktop. You pick the size and color of the notes. Operating System: Windows
14. DocFetcher
Can't remember where you put a file or what you called it? DocFetcher searches the text of your files to help you find the document you were wanted much faster than you would with the built-in Windows search feature.
