Can I disable Mixed content "Help" components of Sharepoint? Sharepoint 2010

My question is about mixed content in SharePoint websites, i want everything in SharePoint to be over HTTPS.

For the scenario, let's say i have a SharePoint 2010 portal with everything running on HTTPS.

I've noticed that when a user clicks some link about SharePoint help, it get's a lot of mixed content.

Navigating in a portal, and clicking in help, will open:

 - https://my.site/EN/content/_layouts/help.aspx?Lcid=1033&Key=WSSEndUser_ListOLists&ShowNav=True

this page will have lot's off content in HTTP, like the following:

- http://officeimg.vo.msecnd.net/_layouts/MicrosoftAjax.js?b=5692....

- http://officeimg.vo.msecnd.net/_layouts/jquery.js?b=5692...

- http://office.microsoft.com/en-us/jsonstrings.aspx?b=5692....

How can i turn off mixed content in the webportal?

Is this possible? If this is by design, and it poses a security issue, how can i mitigate?

Thanks
