I have an unfortunate problem: my old Win Xp installation has died, probably due to the hard drive failing. The drive now fails all SMART tests, but I can get files off it OK.

I have now installed Windows 7 on a new drive, and want to transfer files from the old drive. However, some sensitive files were in an encrypted folder (I think EFS?). How can I un-encrypt them, given that I have essentially my entire old XP installation on disk? Thanks!

If you used EFS encryption on these files and had not exported the EFS certificate, and private key and don't have a valid backup of the system from before it failed then I think your files are gone for good.

You'll need to fire up the XP installation and export your EFS private key.
