Reading: How to Encrypt Files on Windows
Some Windows operating systems besides come with Encrypting File System ( EFS ), which lets you encrypt any kind of file, angstrom well as whole folders and subfolders. note, however, that EFS is only available for Windows 10 Pro, Windows 8 Pro or Windows 8 enterprise. Users with a Home edition of Windows will need to use either Office Suite encoding or a third-party solution, such as VeraCrypt or 7-Zip. Nor does either of these methods offer full-disk encoding, which encrypts your integral hard drive and its partitions. That can be done with Bitlocker, which again is only available to Pro and Enterprise accounts. To set up your Windows file encoding, you ‘ll want to follow these bit-by-bit instructions .
Before you start
Before you start altering your files, there are some tips you need to keep in thinker .
- Any file can be decrypted if you’re targeted by a savvy enough, or well-financed foe. You might want to find a paid solution if your files are truly valuable.
- Files encrypted using the below methods can still be deleted, so you might want to have a backup on a secondary location.
- If you lose your encryption passwords, you’ve lost your encrypted files forever. So, again, keep an unencrypted backup of the file on a physical drive somewhere safe where it won’t be found.
How to encrypt files using Microsoft Office
This process encrypts individual files compatible with Microsoft Office applications such as Word, PowerPoint or Excel. once you encrypt a file this way, you ‘ll need to reopen it in Microsoft Office.

How to delete temporary files
You ‘re not quite done even, though. One of the flaws with Microsoft Office ‘s encoding is that unencrypted versions of recently opened files might still be stored in your computer ‘s irregular memory. You ‘ll want to go clear that out after you ‘ve encrypted a file .

How to Encrypt Files on Windows using Encrypting File System (EFS)
EFS works by letting you apply encoding to already-existing files or folders in your charge system. You can still edit or modify these files or folders following the encoding process.
once again, this is available entirely to Enterprise and Pro versions of Windows 8.1 and Windows 10. Users of the Home versions of those platforms wo n’t be able to use EFS. With EFS you wo n’t notice any change in the direction you access your files ; all you have to do is log in to your Windows score at startup and the files will be accessible. however, this means that you need to pick a impregnable, difficult-to-guess password for your Windows user report. Note: Step 8 is time-sensitive, so make sure to click the “Back up your file encryption key” prompt after confirming attribute changes in step 7. Missing that prompt means you’ll need to start over again.

How good are Windows’ encryption services?
Windows ‘ built-in encoding is n’t a perfect solution. If you encrypt a one file, the calculator stores an unencrypted version of that file in its irregular memory, so a understanding spy can calm access it.
It ‘s fairly easy for an attacker to break Windows encoding using a brute-force attack, which is when an attacker uses a program that methodically guesses every possible combination of letters and numbers, starting with common passwords. If you ‘re identical dangerous about security and privacy, you might not trust a Microsoft solution. The FBI and NSA can require U.S. companies to hand over data or encoding keys. For those reasons, we suggest using a rid third-party service such as VeraCrypt or WinZip .
