Microsoft has released five security related updates for Windows 10 builds 10074 and 10122



From SuperSite for Windows:

No doubt that almost four million hearts skipped a beat when the Ring Master, Gabe Aul, tweeted that there were some updates for Windows 10 and Insiders should open up the Windows Insider app on Windows 10 to see what they are about.

I am sure many headed into Windows 10 hoping for an OS update however, that was not the case as the Windows team is just taking care of the security of your preview install.
