Where are the RMB and LMB keys in the registry and what do they look like?

Question

Windows Registry

Good afternoon.
Please tell me where in the registry to look for the keys of the left and right mouse buttons, and how they should look by default.
Retrospective - Advanced SystemCare was installed (everything is clear here, but it already happened) and after that they somehow did not respond the first time with LMB and RMB. ((
Thank you!
