If you have the issue that JNLP files don’t open correctly anymore with Java simply copy the code below in a .reg file and import it to your registry.

Pay attention that this example here is for the Java 8 Update 201 (last free version) version and you may need to update the path to your jp2launcher.exe file.

Windows Registry Editor Version 5.00

@="JNLP File"



@="\"C:\\Program Files (x86)\\Java\\jre1.8.0_201\\bin\\jp2launcher.exe\" -securejws \"%1\""

@="URL:jnlp Protocol"
"URL Protocol"=""



@="\"C:\\Program Files (x86)\\Java\\jre1.8.0_201\\bin\\jp2launcher.exe\" -securejws \"%1\""

"Content Type"="application/x-java-jnlp-file"
