Step 1. Check if your computer is not infected with a virus

As we have already mentioned, the most frequent reason for this error is malware infection, so system check with anti-malware should help you to detect the cause and get rid of it.

Therefore, if you receive a pop-up window that informs about missing Javaw.exe error, you should download a reliable anti-spyware, such as Reimage Reimage, and initiate a full system check.

If the culprit of the error is not a virus, Javaw.exe error most probably is triggered by a corrupted Javaw.exe file. To check that, you should open Windows Task Manager and check your PC's CPU usage. Actually, you should check CPU usage quite frequently. To do that, you have to:

1. Click Ctrl+Alt+Del at once and open Task Manager;
2. Open Processes tab and find the javaw.exe file.
   

The genuine javaw.exe file does not consume huge amount of memory, so if the file that you have found uses an excessive amount of memory, most probably you are encountering a fake one.

In case malware is not the culprit of the javaw.exe error, the problem was probably caused by old version of system files. To check and fix that, please try the following methods.

Step 2. Make sure that location to the Environment variable path is correct

1. Press Win+R keys.
2. Type sysdm.cpl in the Run window and click Enter.
3. Navigate to the Advanced tab.
4. Click on Environment Variable button at the end of the window.
5. In the category System Variables click New… button.
   
6. In the Variable name box enter Path.
7. In the Variable value type the correct path which by default is C:\\Program Files\\Java\\jre7\\bin for java 1.7.x on a 32-bit version of Windows, C:\\Program Files (x86)\\Java\\jre8\\bin for java 1.8.x on a 64-bit version of Windows, etc.

Step 3. Reinstall Java

First of all, you have to uninstall Java:

1. Open Control Panel.
2. Navigate to Uninstall a program (or Add/Remove Programs).
3. Find Java, select it and click Uninstall button.
   

Once you uninstall it, go to java.com website and download the latest version of the program which is compatible with your computer.

Step 4. Fix Windows Registry problems

The following steps require making changes to Windows Registry. We highly recommend creating backups of the Registry in case something goes wrong.

1. Click Win + R.
2. In the Run box, enter regedit and click Enter.
3. Navigate to HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\javaws.exe.
   
4. Right-click javaw.exe folder and delete it from the system.
5. Restart your PC.

In case the methods provided above did not help, we would recommend you to reinstall Internet Explorer because it may be the cause of the javaw.exe error. For this purpose, perform the steps regarding Java removal, except that you have to uninstall Internet Explorer (or another web browser).
