- Create destination folder where you can RWX (e.g.
- Download jdk exe from Oracle (e.g. jdk-8u72-windows-x64.exe)
- Unzip the tools.zip found inside it into the destination folder
- Open cmd.exe, run:
cd C:\jdk8 for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar"
This solution works for JDK 8 too, without the Admin authority.
