I have recently had to install a new copy of Windows XP Pro because my previous installation became corrupt. I went out and bought a new hard drive and installed a fresh copy of Windows XP SP1 oem. I saved my profile from the old installation. I have just recently noticed that a important folder I have on another drive (E:) was encrypted from the previous windows installation. I had been playing with the encryption built into windows XP and forgot to decrypt it or export the keys before the new install. I believe I should have the keys stored in my profile that was saved but I have know idea how to use those keys to get my files back??? I tried using Advanced EFS Data recovery but It says it does not work on dynamic drives. I am able to decrypt with AEFSDR but the files are un-readable when opened?? Not sure if it matters but I have used a newer windows XP Pro SP1 CD on this new installation and the old install was from one of the original Windows XP CD from a couple of years ago. I've heard they use different algorithms?? Does anyone know how to get my folder and files decrypted? Do I need to re-install windows on another drive using my old Windows CD? Does windows need to be activated first?
