Desktop and Documents Vanished. Recovery only retrieves corrupt files - Microsoft Community

i lost entire harddrive contents on surface pro3 when logging in on work domain. serious problem, least. 

i think everyone's first reaction might "malware" or "virus", not happened. these issues seem inherent windows , surface pro. please read on...

here's happened:

 

i made change in group permissions on local machine (i need able control power options, surface pro locking out though had local admin privilege). worked fine logging in, had inadvertantly created software conflict adding permissions guest users group (adobe did not guest group license). signed in administrator , removed guest users permission had added, leaving else same.

 

logged out , logged in under user account (not admin), , @ login, surface treated login if first time using machine.

 

even more troubling, of documents , icons had vanished desktop. harddrive showed had 400gb available, before there 3gb available (yes, know low space).

i checked user profiles, , empty. and, yes, hidden files set show...

 

we began working pro, ran couple of recovery tools. recuvar , easeus. both showed lot of promise, seemingly finding missing files, ultimately, nothing recovered can opened. jpg, word, pdf, give error corrupt , cannot opened.

the professional felt bitlocker had somehow caused catastrophic failure encrypting files, while windows had somehow built new profile over-wrote previous profile.

i @ complete loss why happened!!!

the professional turned off bitlocker , attempted recovery again.

to no avail, recovers claims in "excellent condition", not open , deemed corrupt software attempts open it.

what steps can take now? hope lost? have files "recovered" saved on separate drive, of no use.

please help!
