Windows: What is jucheck.exe?

"What is jucheck.exe?" - You ask yourself this question at the latest when the Windows user account control asks again whether you want to assign rights to the process. Many users are unsettled by the apparently strange name of the file. However, "jucheck" stands for nothing else than "Java Update Checker".

The Java Update Checker - This is hidden behind the jucheck.exe

Java is a programming language and runtime environment that is usually installed on every Windows PC. But what is jucheck.exe responsible for?

• Security gaps in Java arise again and again. They are regularly fixed by the manufacturer Oracle. Each time an update of the software appears, a revised version.
• The update is automatically downloaded and installed on your Windows computer. The jucheck.exe file ensures that the current (and therefore the safest) Java version is always installed on your Windows PC: It checks whether Java updates are available. Hence the name "Java Update Checker", or "jucheck" for short.
• So if the Windows user account control sounds an alarm because of jucheck.exe, don't worry: you can allow the process. For security reasons, you should.
• However, if you want to deactivate the automatic Java updates, you will find out in the article "Jucheck.exe: Setting up Oracle's Java update" what you have to pay attention to.
