Remove unwanted programs, review installation changes and check supported applications for updates.
## Remove unwanted software and review installation changes
Ashampoo UnInstaller Pro 27 combines program removal, installation monitoring and maintenance tools. Use it to review installed software, remove applications you no longer need and examine files or Registry entries that may remain after a standard uninstall.
Start with the program you intend to remove and check whether it contains settings or personal data you want to keep. A removal tool helps organize the process, but the result still depends on the application and the changes it made.
## Record new installations for later removal
Installation monitoring records changes made while software is installed. These logs provide information for a later uninstall, while the five-stage removal workflow combines removal methods with additional cleaning.
Keep the monitoring session focused on the intended installation. Review the application identity and the proposed cleanup before confirming removal, especially if the computer contains shared components or software used by other people.
## Analyze applications installed without a log
Forensic analysis can create retrospective uninstall logs for supported existing programs. This provides another route when an application was installed before monitoring was enabled.
A retrospective analysis is different from a record captured during installation. Review the findings rather than assuming that every suggested item belongs exclusively to the application being removed. Keep an independent backup before making broad changes.
## What is new in version 27
Software Updater checks installed applications for available updates and can process multiple updates together. Direct installation depends on the software vendor; filters exclude sensitive components and programs with their own update mechanisms, and you can exclude selected programs or versions.
Version 27 also improves program and app detection, post-installation analysis and log creation. A size comparison identifies differences between recorded and actual program sizes, while expanded categorization helps organize the software list.
## Inspect snapshots and cleaning results
System snapshots compare changes between two points in time. Cleaning history records maintenance actions, and uninstall logs can be exported as HTML, CSV or TXT for further review.
A snapshot comparison is an analysis tool rather than a complete recovery image. Use it to investigate changes, and keep your backup plan separate. When sharing an exported log, check whether its file paths or other entries reveal information you want to keep private.
## Use maintenance tools for a specific purpose
Additional modules include Registry Optimizer 2, its cautious Super Safe Mode, Crash Analyzer and Privacy Traces Cleaner. These support maintenance and investigation alongside software removal.
Choose the module around an observed problem instead of applying every cleanup at once. A crash report can help identify a recurring issue, but it does not establish its cause. Clearing local browser traces also does not remove records held by websites or services.
## Build a repeatable software-management routine
Review installed applications periodically, preserve important data before removal and confirm the remaining software still works afterward. For updates, check the completed results rather than assuming every detected program was updated successfully.

## Ashampoo UnInstaller Pro 27 FAQ
### What is Ashampoo UnInstaller Pro 27 used for?
It removes unwanted programs, monitors installations and helps review remaining files and Registry entries. Maintenance and analysis modules support related software-management tasks.
### What does version 27 add?
Software Updater checks for application updates and supports batch processing. Other changes include improved software detection, retrospective analysis, log creation, size comparison and program categorization.
### Can it analyze a program installed before monitoring was enabled?
Yes. Forensic analysis can generate retrospective logs for supported existing installations. Review the findings because an inferred log differs from changes recorded during the original installation.
### Does Software Updater update every application automatically?
No. Coverage and direct installation depend on the application vendor. Some components and programs with their own updaters are filtered out, and you can exclude programs or individual versions.
### Does a system snapshot replace a backup?
No. Snapshot comparison helps inspect differences between two states. It is not a complete recovery image; keep independent backups of important files and your working environment.
### Can I export uninstall logs?
Yes. Export formats include HTML, CSV and TXT. Review the contents before sharing a log, particularly file paths and other potentially personal information.
### Does deep cleaning guarantee every leftover is removed?
No. Results depend on the application and the changes it made. Review suggested removals, preserve data you need and check that other applications still work after cleanup.
