Widevine CDM 970 is failing to load on  Windows 7 due to a sandbox violation. Widevine tells me this is because they're calling RtlGenRandom() and our sandbox is blocking that.

Chris, is this fix covered by automated tests? Would manual testing be beneficial here? If it's a yes for the latter, could you please let us know what and how to test it?

Our automated testing cannot cover this, it's hard. I don't think we need manual QA on this.
