I am using https://github.com/mj1856/SimpleImpersonation to impersonate an administrator so I can make changes to windows services from an app that's run by a user who is not an administrator. This works on Windows 7 with no issue. On Windows 10 I have to right click on the app and click run as administrator for it to work. Otherwise I get an error code 5(Permission denied) when my app tries to modify the services. The impersonation appears to be working. UAC is turned off. I don't see what to try next. I'm doing this from a winform app if that matters.
