It's the file.  I have only a restricted understanding of file
permissions, but here's what I get out of explorer:

Directory c:\texlive\2015\texmf-var\web2c\tex has the following
permissions set for group 'Benutzer' (Users):

  Read, Execute             +
  List directory contents   +
  Read                      +

Those permissions look quite ok to me and the group name sounds very
familiar.

After installation format c:\texlive\2015\texmf-var\web2c\tex\tex.fmt
has no such permissions for group 'Users'.  I think this is the culprit.

After running icacls the following permissions are set on the file for
group 'Jeder' (Everyone).

  Read                      +

But those permissions are lost as soon as 'fmtutil-sys --all' is run.

I tend to think permissions for group 'Users' instead of 'Everyone'
should be preserved on format files.

Screenshots attached.

Best regards,
