I have win 7 ultimate 64bit and a while ago i tampered with file encryption and was dumb enough not to back up my encryption key. However, i remember my password that i used to encrypt those files. I formatted C: and re-installed Windows 7, just to notice i can't access some of my important files on another drive.
So, i thought several possibilities of recovery, and i appreciate if you guys could express if any of the options below are viable.
1) Since i didn't back up my encryption key, where is the original one located? (if i use some recovery program to restore it)
2) Can i use recovery programs to restore pre-format a) user account, or b) encryption key, or c) windows (which actually then works)?
3) I remember the password i used to encrypt the files, so can i just make a new encryption key and kind of import it to my present windows to decrypt those files?
4) Does "Advanced EFS Data Recovery" or some other encryption key recovery tool work for my problem?
Sorry for being a total noob and asking for help, but i really, really would appreciate any help i can get on this matter.
