Share applications between users in Windows 10
On this Windows 10 PC I am A, I would like to set it up so that another user B can easily use "my" Picasa and Spotify from her Windows account.
Ideally with my settings and their file-permissions.
Doesn't have to be very secure, but B should not get access to my password or admin rights.
(Having the apps under a 3d account C would be OK).

I don't think that can be achieved in the way you would like to have it.
As you probably noticed yourself, it's easy to install the application in such a way that it is accessible from all Windows user accounts. But the logon information is bound to each specific account. This makes it possible for multiple users to each have their own Spotifiy, for example.
So, if you wish to share your Spotify account (which I doubt is covered by the Spotify license), you have to provide your logon data to the other user.
Of course, you could just be with the other user when he is logged on and then enter the password yourself, thus not revealing it. User B would now be given full access to your Spotify account, including the possibility to change the password. And like I said, you could run into license issues and risk blocking your account.
Just use Spotify the way the company intended: Create a separate login for each user, then share your music with them from within Spotify. Unless User B wants to listen to lots of ads, this won't come for free, but you might be eligible for a Spotify Family Plan.
I don't know Picasa well enough but I'm pretty sure it's similar.
