Windows 10: .jar files only execute through CMD

Every once in a while, my pc no longer recognizes a default app for jar files and I have to manually run them. I can open them with the command 'javaw.exe -jar' but they will not open otherwise. I have gone to Task Manager to check the path of the javaw.exe that runs when I successfully execute files using the command, however, when opening a .jar in File Explorer using the same javaw.exe, it does not execute. So, what I want to know is: What's going on, and how can I use File Explorer to run .jar files?

I have a problem i upgraded to windows 10 and i suddenly was unable to open .jar (java) files.

I used to be able to just double click the .jar file or , open with java(TM) platform SE binary ,.

I found a solution to that problem , by win+r (run) running :CMD and navigating to the file map, and typing this command: java -jar [FileName] than it finally worked/opened. this method is very time consuming
and i have to run all those codes .

now is the question: how can i get java to work fully?

what i want is that i can simply click the .jar file and just open it. because the method in the console is hard an time consuming

this worked on windows 7/8 how can i fix this?

is i now click the file set to open with java a window pops up for a split second it seems empty(a CMD like window).

* I have the latest version of java.

* I have tried removing and reinstalling java.

* I am an gamer and i have a relay good/fast PC so that can not be the issue.

I followed your instructions

and java:"Java(TM) Platform SE binary"was already selected

and i like to know how to fix this cause is is quite annoying.

 

jar files

Fixing .jar file opening on Windows requires two steps:

• Open the Control Panel, and chose "Default Programs - Associate a File type or protocol with a program". Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as "Java Platform(SE)".
  A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the "Change..." button.
• Now open the regedit, and open the HKEY_CLASSES_ROOT\jarfile\shell\open\command key. Luckilly for us, we may specify parameters there for the (Default) value. This is normally: C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

I Hope this Answers your Question!
