Is EFS feature in Win 7 Pro any good?

post #1 of 3
Thread Starter 
I was hoping to start keeping my bills/records on my PC, but I am scared and I asked Google and all he wanted to talk about was how easy it was to do with just one click. I am not looking to keep the NSA out of my cable bill just my girlfriend/ her friends/ the degenerates I hang out with and the guy that may in the future steal my PC. Thoughts?

EFS and a password would likely keep these people out of your data. Don't lose your password or encryption key though, as standard recovery methods won't decrypt your data.

The big downside with EFS is it's very difficult to use anything but Windows to read your data in case of issues, even if you have the keys, because they lack an ESF component driver. Another potential issue is that many files aren't wiped or overwritten after encryption, they are just copied, so potentially unencrypted sensitive data may still be recovered from the drive, unless you manually overwrite the free space on the drive.

Personally, I prefer just using TrueCrypt to encrypt entire drives. Your CPU has AES-NI so wouldn't suffer too much overhead from such a thing.

I'm sorry I don't fully understand this part. Could you expand on this? Do you mean every time the folder is enc/dec that the unencrypted copies are still floating around the drive?

Appreciate the info.
