This is an older, unsupported version (released around March 2018). Oracle no longer provides free public updates for JDK 8u202 and earlier. For security and bug fixes, you should use a newer JDK version (e.g., JDK 8u211+, JDK 11, 17, 21, or later), or use OpenJDK builds (e.g., from Adoptium/Eclipse Temurin).
Once the download is complete, follow these steps to install JDK 8 Update 161 on your Windows x64 system: jdk-8u161-windows-x64.exe
