How did you encrypted them?
Did you used BitLocker?
Was it local account or Microsoft Account?
Was it under the Domain-Joined account?

If these files are encrypted by EFS and you didn’t save certificate in advance, I am afraid that you couldn’t access to them now. Your best bet is asking for help from data recovery company if these files are important.
