When uninstalling programs on Windows, users may sometimes encounter situations where an application does not appear in the installed programs list, its uninstaller is missing, or leftover files remain after removal. In these cases, the Custom Uninstall feature in Wise Program Uninstaller provides a way to manually locate and completely remove unwanted software.
What Is Custom Uninstall?
Custom Uninstall is an advanced uninstall method that allows users to select a program’s installation folder manually. Wise Program Uninstaller then searches for files, folders, and registry entries related to that program and removes them, which is useful when:
- The program is not listed
- The uninstaller is missing
- Leftovers remain after removal
- You only have the program folder
How to Remove Unwanted Software Completely Using Custom Uninstall
Follow these steps to remove a program using Custom Uninstall.
Step 1. Open Wise Program Uninstaller
Run Wise Program Uninstaller as administrator on your Windows PC. Then, click the Custom Uninstall tab from the main interface.

Step 2. Select the Program Folder
Click the Browse button and locate the installation folder of the program you want to remove. Common installation locations include:
C:\Program Files\
C:\Program Files (x86)\
C:\Users\YourName\AppData\Local\
C:\Users\YourName\AppData\Roaming\
Select the folder that belongs to the application and click Next.

Step 3. Scan for Leftovers
Wise Program Uninstaller will use the folder name as a search keyword and look for related uninstall information, files, folders, and registry entries.

Step 4. Remove the Program
After scanning, review and check the detected results carefully. Make sure the listed items belong only to the program you want to remove. Removing unrelated registry entries or system files may cause other applications to malfunction.
If the results are all correct, Select all and click Remove.

Wise Program Uninstaller will create a backup of selected items and then delete the detected files and registry entries.
If necessary, repeat the steps several times to completely remove all the leftovers.
Please Note: Custom Uninstall is designed for special situations. For normal applications, Safe Uninstall is usually the recommended option because it uses the program’s official uninstaller and then removes leftovers.
Conclusion
The Custom Uninstall feature in Wise Program Uninstaller is a powerful solution for removing hidden, broken, or unlisted applications. By allowing users to manually select a program folder and scan for associated files and registry entries, it helps clean software more thoroughly than traditional uninstall methods.
