Performance :: Previous Versions Does Not Work On System Drive But Second Drive

I have two physical disks in my notebook, one simple partition each, BitLocker encrypted. Drive C:, which is my system drive and drive D:, for some media stuff.Windows Version is Windows 10.0.10586 x64.I have configured VSS to use the "Previous Versions" feature in case I accidentally delete or overwrite a file. I did this on my Win7 install to and it saved my butt at least three times.

VSS is running (Volume Shadow Copy Service set to "Manual"), snapshots are there but when I right-click on a modified file (or on the root of the disk) and click "Previous Versions", my D: drive correctly displays the existing snapshots, on my system drive C: there is always a "There are no previous versions available" message. But, when I click the "System Restore..." button, I get a list with my snapshots, so I guess I could restore my system.

configuration seems to be ok and the two manual snapshots are there on both drives. For the moment there is no system restore point, but it does not work with snaps created by them either.
