Boot Camp's control panel doesn't work after windows 10 upgrade

Hi everybody...I have a strong dilemma!

I am using a Macbook Pro Retina (early 2013) where 2 years ago I installed windows 7 in a 100 Gb partition...everything was working perfectly.

Yesterday I have updated my widows 7 partition to windows 10...a good choice considering that windows 10 works quickly and efficiently.

No problem with the installation, but I have a big problem with the Boot Camp installed (version 4, build 4326)...It doesn't work. I can't use the trackpad, and manage all the Boot Camp setting because the control panel doesn't work. When I try to open it an error appears communicating that "an error occurs during the attempt to access to the configuration of the access disk - perhaps you don't have the permissions to modify the access disk".

I've tried to download and install other version of the Boot Camp, as different release of the version 5, but a message appears saying "this is not the proper version for this computer"...even the last 6 version (build 6133) report an error during the installation 😠.

I have already tried everything and I am quite desperate 😟...could you help me please!!!???
