Wix create silent uninstall file - wix

Question

my idea is make an uninstall file with .msi install file. I read some information about creating uninstaller shortcut here: http://wixtoolset.org/documentation/manual/v3/howtos/files_and_registry/create_uninstall_shortcut.html , But i cant found information about make uninstall file after msi build , maybe whom know it's possible ? and if possible how i can do it ? or maybe it possible to do with cmd script? Just write script for automatically uninstall my program from mashine. My code is :

In general you are not supposed to put uninstall shortcuts in the start menu, it is in fact a violation of Microsoft's logo requirements for Windows applications I believe. Rather you should let people uninstall your product the normal way via the add/remove programs applet.
UPDATE: I found this answer with some more information on this topic: Shortcuts with name "Uninstall <Program Name>" are not displayed in Windows 8/8.1/10
Also, just so it is clear, uninstall, is a built-in feature of MSI files - it is always automatically available unless actively blocked (such as some applications hiding themselves from display in add/remove programs). There is nothing extra you have to do in your WiX sources to support uninstall properly. Just follow Windows Installer guidelines and it comes "for free".
If what you are asking is for a way to create an uninstall batch file, then you can find a plethora of ways to uninstall your MSI file in this "uninstall reference": Uninstalling an MSI file from the command line without using msiexec.
In short, just run the command line below to uninstall your MSI if you have the MSI's product code (you can find your product code by querying your system as described here: How can I find the product GUID of an installed MSI setup? - you might need to look it up since you auto-generate your product code):
msiexec.exe /x {your-product-guid}
or just uninstall by referring to your original MSI installation file like this:
msiexec.exe /x "c:\filename.msi
See the linked answer above (the uninstall reference) for a lot more information about this.
