What I can do as files lost due to Windows 10 upgrade?

Some people lost files after Windows upgrade. This is why we suggest customers to do backup for files in drive C:, you have to do this to avoid any data lost, or you can say even you lost your data, you will still have one way to get the files back.

If you don’t have backup your files, the only way to recover files is to use the 3-rd party data recovery software. Hdata Recovery allows Windows upgrade file recovery, you can find out all your lost files within 5 minutes or less.

The best point to use Hdata Recovery is that it’s a safe file recovery tool. You don’t have to worry about the data overwritten, which will destroy the files system and make files corrupted. You know the overwritten will cause the failure on file recovery.
