Windows 10 problem

[Gussy]

Many thanks Simon,

Getting a bit lost here, my laptop is all in German...

But I´ve located a list of file extensions in the system settings - .jar is there, the description is JAR-Datai and then in the next column the heading is something like: Current Standard and it lists "Provisioning package runtime processing tool"

Is that right????

Once again, many thanks for your advice!
