Is this program a Microsoft Store App? If so, you can try to use PowerShell Commands "Get-AppxPackage" to check the program info and then use "Remove-AppxPackage -Package -AllUsers" to uninstall it. I have tested it on my own Windows 10, after login with another user, command "Remove-AppxPackage -Package ” will report “Package was not found”. But with an additional “-AllUsers”, the command performed successfully to uninstall the app Facebook, it disappeared in the output of "Get-AppxPackage".
Besides, generally can’t find the uninstall program of a software divided into several scenarios:
1.It's green software use without installation. If you want to clean it up, you don't need to uninstall it, just delete the folder where it resides.
2.It's malware, or malicious software. If this is the case, it is necessary to use anti-virus software to scan.
3.A less likely scenario, some software editors may inadvertently forget to write the uninstall program, usually private or amateur programmers will appear in this situation, the solution is the same as the green software.
4.You can also try to check if the program can be opened and working fine, sometimes software that does not have an uninstall program in the source file is corrupt. Simply delete the source file.
- Also some software may be providing a Repair/Uninstall option, you can try to uninstall it by clicking the install software.
