Previous releases have separate uninstallation instructions for Java Web Start. Uninstalling the JDK or JRE will not, however, remove the cache for previous versions of Java Web Start. The only way to uninstall Java Web Start is to uninstall the JDK or JRE. The is a registry string in the "JRE" or "Java Runtime Environment" key. "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime = 1.8 "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.8.0" "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.8" "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\JRE\ = 10
The is a registry string in the "JDK" or "Java Development Kit" key.įor the same example, if the JRE is installed, then the registry layout is: "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development = 1.8 "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.8.0" "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.8" "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\JDK\ = 10 "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit" for JDK 1.8.0 and "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\JDK" for JDK 10. For example, if JDK 1.8.0 and JDK 10 are installed, then the following registry keys are created: If there are two versions of JDK or JRE installed on a system, one with the new version-string format introduced in JDK 10, and the other with the older version format, then there will be two different CurrentVersion registry key values. HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Web Start\ RuntimeLib: the full path name of the Java runtime DLL
JavaHome: the full path name of the directory in which the JRE is installed
This key contains the following string values:
