Executable run from zip file by 7zFM has more privileges than when run directly after extraction?

    I was trying to investigate wether/how running an executable fro inside an archive disabled some permissions.
    I looked at the Security tab of Process explorer. For an exe run normally from a folder(admin account), and the same exe run from a zip open by 7zFM.
    To my surprise, the exe run from inside has 2 more privileges : SeRestorePrivilege, and SeSecurityPrivilege.
    I don't really know what those privileges allow, but it doesn't seem to make sense to have more privileges in that case, does it?

    Those privileges sound useful to 7z itself. Since 7z starts the executable, that process might inherite privileges from 7zFM...?

    BTW: read https://msdn.microsoft.com/en-us/library/windows/desktop/bb530716(v=vs.85).aspx if you're comparing privileges but don't know what they mean.
