System Integration in 2.7

Have got a multiple boot -system: W7 Pro and W10 Pro.
Both of them I updated to S&D V2.7 and on both of them my account is one in type Administrator.
In both systems the Setting option 'System Integration' lets Windows Explorer crash when clicking the right button on a map in the left window.
Explorer then will be restarted automatically.

So I decided to disable this system-integration: in w7 I had no problem disabling it. In W10 however it was greyed out, so I could't do anything. Checked my account: type was Administrator.
I had to login using the Administrator account to get the change done

So after all I managed to disable the integration, but it is kinda peculiar. I'm not sure but I think I had the same problem in previous S&D versions.

Could it be I'm dong something wrong?
