Instructions
Download and install a program such as the examples provided in the Resources section. They will either be free or will include a free limited-time trial period.
Using 7-zip, a free RAR extractor for Windows: Right-click your RAR file and click "7-Zip." A new menu will appear. Click "Extract files." Select a location for the extracted ISO file, and click "OK" to place the ISO in this location.
Using WinRAR: Right-click the RAR file and click "Extract files to." WinRAR is not free, but many consider it to be the best archive manager available. Select a location for the extracted ISO and click "OK." Your ISO will be extracted to the location specified.
Using RarZilla: Right-click the rar file and click "RarZilla" to extract the file to the same directory where it is located. RarZilla is free and works very well.
