Javaw.exe is a process that launches Java programs (jar files included). However, a Windows cannot find javaw.exe error message can pop up for some users when they try to launch Java software.

The full error message states: Windows cannot find javaw.exe. Make sure you typed the name correctly, and then try again. These are some of the best fixes for that error message.

What to do if javaw.exe is missing on Windows 10?

1. Scan for malware

If you already use Eset Internet Security, open the main window and follow these simple steps:

1. Select Computer scan from the ribbon on the left.
2.  Click on the Scan your computer button and wait for the process to complete.
3. When the scan is finished, you will get a report showing the number of scanned, infected, and cleaned objects.

Alternatively, if you do not have Eset Internet Security on your computer, you can still do a full computer scan with its free scanner. You can download it for free and it will thoroughly scan your computer just as we showed in the steps below. You can only run this utility once, but it can be a quick fix if you don’t use an antivirus already.
