How to Disable or Enabled EFS Encryption in Vista

Information

Encrypting folders and files is a way to protect them from unwanted access. Encrypting File System (EFS) is a feature of Windows that allows you to store information on your hard disk in an encrypted format. Encryption is enabled by default in Vista. If you disable encryption, no user account will be able to encrypt a file or folder.

NOTE

The EFS Encrypt feature is only available in the Vista Business, Ultimate, and Enterprise editions. It will remain grayed out in the Vista Home Basic and Home Premium editions.

WARNING

Be sure to decrypt all files and folders before you disable encryption. Once encryption is disabled, all user accounts will lose access to encrypted files and folders until it is enabled again.

You have Home Premium if thats correct then you cant use Encrypting File System as it is only available in the Business, Enterprise, and Ultimate version of Vista.

I encrypted several hundred pictures when I had Windows XP. I upgraded to Vista Home Premium and I found out that I can't decrypt them. Any ideas? I was thinking about taking the HDD to a friends house that has XP on it and trying to decrypt from his OS, since I don't want to downgrade to XP...

Hello Tetsujin210,

Unless you have the EFS certificate from your old XP to add to your friends XP so that you can decrypt them, you will not be able to access them. I'm not sure if this is the exact same method for XP, but this shows you how to add (restore) a EFS cetificate in Vista if you have a copy of it.

Encrypted File System (EFS) Certificate Restore

Hope this helps,
Shawn

Please help: I read in PC Magazine that Vista Ultimate has a nice feature to prevent reading\theft of personal files (i.e. encryption tool) in case a notebook gets stolen.

So, I followed the PC Magazine recommendations and encrypted my personal documents, music, and pictures by right clinking each folder, Advanced, Properties, and Clicking Encrypt. The process took about 2 hrs. I thought all was well but then when I started my computer the next day, and when the desktop loads, there is a message indicating, "Encryption File System needs your Smart Card". When I click this message, a window pops up stating:

Encryption File System
You are encrypting a file or trying to access an encrypted file using a smart card
Enter your Smart Card PIN
Insert Smart Card or
Swipe Finger to Log On

Now, I cannot access my files that I encrypted

My guess is that once I encrypted the files, Vista needs to export the encryption certificate to a Smart Card. Without this, I cannot decrypt my files again. I went to Best Buy, Radio Shack etc and no one sells these cards or card readers. Found a few websites to purchase a Smart Card Reader and Smart Card.

My questions are:

1) Can I decrypt without a Smart Card/Smart Card Reader. I tried going to each folder, right clicking, properties, advanced, and checking decrypt but the above window pops ups.

2) If I do purchase a Smart Card Reader/Smart Card will the certificate be exported and can I then decrypt to make my files as they were prior to the encryption?

3) Is there anything else I can do?

Thank you for your assistance!

Steven

Hello Steven, and welcome to Vista Forums.

Could you post back the link for that article? That does not sound like it was the EFS feature in Vista.

In the mean time, you might be able to use the 30-day trial of the program Advanced EFS Data Recovery to decrypt the files.
