    Application associated with an extension is not "sticking"

    I just recently changed my OS to Win 8.1 (from Win 7) and a java application I have (*.jar) is pointing to Python to open it. THis is obviously wrong. If I download the latest version of Java and install it, the icon changes and the app works great. The "jar" externsion is associated with java. When the PC is rebooted a few days later, the icon is now the Python one and "jar" is now associated with Python.

    How can I get it to "stick" that *.jar is associated with Java?

    Thank you.

    You will need to clear the Value Data for the PersistentHandler subkey.

    This reg file should do it. Make sure you sign out/in to apply the change.

Will there be a means for Metro "Daemons"/servers/GUI-less application
I'm just wondering if there will eventually be a means of running a Metro-compliant background task, such as Notification Area Icons In Win78 and Desktop? Theoretically these could be added to the harms menu somehow.
