Ashampoo UnInstaller 11 deletes programs without leftovers and allows you to install, test and remove software without worries. Four deletion methods ensure a more thorough removal than is possible with Windows' default means. This includes unwanted programs, e.g snuck into your system through nested installers or internet-based sideloading. Ashampoo UnInstaller 11 is the ultimate solution against this type of spyware/malware programs and eliminates them all! Getting rid of no longer or never wanted browser extensions is equally easy, even for those little "helpers" that browsers themselves can't or won't list. The installation monitoring technology built into UnInstaller logs all file and system modifications and completely reverses them during software removal. Installations that weren't logged by UnInstaller are still fully removable thanks to the built-in database with hundreds of software profiles and our own Deep Cleaning technology. The program also features snapshot technology to compare different system states and instantly spot modifications. Batch or drag & drop removal of software is also possible. Version 11 features significantly improved installation auto-detection and full Windows 11 compatibility. The new Boot Center analyzes and improves Windows' autorun behavior and tasks while the new category view neatly lists installed applications by category. All cleaners have also been fully updated.
