I use a sat tracking program that as written, is installed in the
/program files/ folder, and apparently with the increased OS security ,
unable to download TLE files directly into the proper folder UNLESS there
is an older file by the same name is already copied there. its a minor
issue and easy to get around., however .INI files ( config file) have
security levels raised to prevent users from editing it, again by OS
level changes. this too is a minor issue, I just modify the permissions
to allow it.

The odd thing, apparently after Win7 and now Win10TP , running the
program creates a hidden folder and a series of sub folders titled

C:\Users\USERNAME\AppData\Local\VirtualStore\Progr am Files

not a problem , however IF you need to modify the program or upgrade
the system created folder prevents the new version from running and
errors out. deleting the hidden folder and rebooting the the computer
allows a new set of the virtualstore folders to be created and all is
fine again.
Did not see this issue with earlier version of Windows..


NOT a compliant just observations of the differences. isn,t that what
running the tech preveiw is all about ?
