    I have 2 normal computers (Windows 7 and Windows 10 so I need this method to work on both OS), by normal I mean they are not inside a domain nor Active Directory, they are just normal computer. I need to install TamperMonkey on them (I know how to do this by going to [login to view URL]) but I want to avoid that anyone can uninstall it, I saw somethings about "ExtensionInstallForcelist" or "Installed by enterprise policy" but there was always issues as this computers are not part of a domain or whatever. Is important that we focus on TamperMonkey, don't explain the method using other extension as example. I also need to know how to update the scripts that I create on TamperMonkey, I saw something like @updateURL but I unknown how to use it, basically I will create a script and install it on Tampermonkey, if this script needs to get updated in the future cause the website where it should work has changed it code, I will create a new version and uploaded to my hosting and the TamperMonkey extension should get the new version of the user script from there.
