This is more of a public service announcement than a need for tech help.

About a week ago, I started to see a nag icon to upgrade to Windows 10. This is apparently because I installed Windows update KB3035583.

I have no intention of upgrading to Windows 10, at least not until I know what kind of performance hit/benefit I will see. I'm currently running Windows 7.

But along those lines, if someone is using the Windows 10 preview and has any comments about performance, I'd be curious to hear what you think.
