Deleted user account, lost everything in My Documents

If it's not in the recycling bin, you can try using a free undelete program.

When you deleting, did you keep your files? Check Recycle Bin. If there in nothing, then no way to recover files.

You've never heard of undelete programs, have you? There are always ways to recover data lost on a hard drive, maybe unless you encrypt/secure delete it.

No, first from you.

Last i tried with recovery soft, didnt work. Years ago.

I've used such software no problem before. If you erase something and you don't recover it before writing a ton of data, Windows might write over it and make it unrecoverable by software. You might have waited too long to use recovery software or done something else such as secure deletion, IDK.

The best data recovery software without a doubt is testdisk open source http://www.cgsecurity.org/wiki/TestDisk there have been times where this software has done a better job of recovering data than from big time hard disk recovery companies that cost mega dollars so give this software a try
a alternative is http://www.oo-software.com/en/products/oodiskrecovery/i... but thats paid for software still very good though
