I think what Arkhi meant was that you must change your current user account password, log off, then log in again, and then try to decrypt the files.

I'm not too sure whether or not that will work though, as the EFS uses a unique internal SID for encryption together with your password. This SID is first created when a user account is created, and remains constant even though you may change your username or password. In fact, Windows warns you that changing an account password may lead to inability to access encrypted data.

Deleting the user account and recreating it with exactly the same name and password won't work, because a new, differemt, SID will be generated that will be incompatible with the already encrypted files.

As I said, what you should have done is either decrypt those files before reloading Windows, or write them to disk. Unfortunately, there is no easy way to get back to those files without an extreme amount of effort.

You have three choices. Go to a data recovery specialist, download them again if you can, or cut your losses and remember to keep backups next time.

I know it sounds nasty, and I'm trying to say this as nicely as possible, but in most cases I've seen, those files are gone for good.
