How do I uninstall programs not listed in the control panel on Windows 10?

Here is what you can
1] Check for its uninstaller in the Programs Folder


Most of the programs are installed in C:\Program Files and C:\Program Files(x86), and they come with an uninstaller script. The same script is registered with Windows. When you run the Uninstall from the Control Panel, it calls the same script.
If the program isnot listed, then you can manually go to that folder, and locate that .exe tool, and run it. It will have the uninstall name appended to it.

2] Redownload the Installer & see if you can uninstall
Some programs offer an uninstaller with their installer. They first check if the program is already installed, and instead of giving you the option to install it, they offer you to uninstall it. See it this options works for you.

3] Uninstall programs using the Registry
You can also uninstall programs using the Windows Registry. Check if this option helps.
4]Use third-party Uninstaller Software


There are a lot of free Uninstaller software like Revo Uninstaller, and many more which can uninstall programs which are missing off the list.
