[python-win32] Python Service does not start at Windows boot but at user's logon

I totally agree with you. I have found another dependency to use : 
Themes, which is less heavy than RPCSS.
This works, but it does not make exactly what I want. Indeed, I would 
like to set some values in a HKLM subkey
at windows boot, in order that changes are effective as soon as a user 
logs in after boot sequence. In my case,
registry values are well written, but changes aren't effective yet... So 
user needs to reboot.
I tried to use the FlushKey() method from _winreg module in order to 
immediately write changes to registry.
Changes are written, but not effective. I thought that user's login 
refreshed the registry, and then changes could
have taken effect, but it seems not to be really the case.
Is there any other Python _winreg method that could force registry 
changes to become effective as soon as
changes are written into the registry ?
