There are four working mode in Revo Uninstaller:
- Built-in: uses the application's own uninstaller without scanning.
- Safe: Built-in mode + registry scans and hard drive for leftover items. (Recommended because it's fastest)
- Moderate : Safe + advanced file scanning
- Advanced: Moderate + deep scan for registry and files. (Slow, but very effective)
