windows 10 downgrade to 8.1 data loss

My client says that the data that was in their user profile is now missing.  I used getdataback to recover deleted data but nothing appears.  I also checked alternate user profiles but the data in documents and desktop seem to have vanished.  Anyone heard of this?

I am not sure why a person would go back to Windows 8 from Windows 10 (10 being the better of the two systems).

Also, proper recover to the prior system should not lose the profile. A number of people have downgraded for whatever reason and their system returned to normal.

I would look in Windows.old for the profile. I think it might be in there. Check Windows,old.

Does your user have a backup?  Of course they do, don't they?

Windows 10 sometimes breaks hardware.   I had to revert back the surface pro because wifi and bluetooth stopped working.   I have seen a successful downgrade.

The end user performed the upgrade/downgrade.  I don't see his data.  Nor do they have a backup.

I don't believe windows.old would retain the user's profile.

If they have no backup and cannot find anything in Windows.old (I was not certain on that one) then they appear to have lost their data (that data which could not be recovered). That is unfortunate.

Windows 10 does not break hardware; rather, manufacturers build one operating system wonders that cannot be upgraded.

If the data has been lost then they have lost their data as noted and that is the answer here.

I posted the question to improve the situation of the data being lost.  Everyone knows it's lost but they are not paying me nor am I paying for assistance to simply confirm our suspicions.  We want the data back.

The data is lost and we said that and you cannot get it back in this situation. Nothing you or they can do and that is the answer for someone else looking at the question.
