Problem with local tex tree after reinstallation of OS and MiKTeX

Hi all!

Today I experienced a strange behaviour after installing MiKTeX due to 
an reinstallation of Windows 10 after the lasted update.

I have all my style file stored in a local TeX tree 
(d:\localtexmf\tex\latex\). This path is also set in MiKTeX Options -> 
Roots as Path. After a Refresh FNDB (user and/or admin) kpsewhich 
returns an empty line.

As a workaround I set a symbolic links to the MiKTeX directorys 
tex-directory. Now kpsewhich is successful.

For years the solution with the local TeX tree worked perfectly for my. 
I did not change the MiKTeX directory (D:\Program Files\MiKTeX) nor the 
location of the local TeX tree.

I tried some alternate locations but was unsuccessful, i.e., pathes 
added, refresh executed, but still no style files.

Any ideas or hints to solve this are welcome. Or is this a bug?

Thanks for your support.

Kind regards,
Marckus
