Right-click, "Run as administrator", and it will tell you whether these mitigations are enabled or not, and it has "disable/enable" buttons.
You can disable the mitigations manually if you want by setting the needed registry keys yourself.
On Sandy Bridge, as of now (28 May 2018), InSpectre should report that the Meltdown mitigation is active, the Spectre ones are not (because the SB microcode is not on Windows Update yet.) You can run your benchmarks and other tests, then disable the mitigation, reboot, and run your benches again. You can then see for yourself whether or not there's a perf hit on the stuff you care about. For gaming, there shouldn't be any noticeable hit. But you can check for yourself.
In my own tests, on an i5 2500K, I have observed a performance difference of exactly ZERO in all my games. Workloads that depend on heavy I/O however (storage or network,) should see a significant perf hit. I do not care about these workloads though, so I didn't run any such benches.
You aren't forced into it. Windows 10 provides a way to disable the mitigations, and Gibson Research has provided a utility that makes it easy to enable/disable meltdown and spectre mitigations in Windows with a click of a button:

In summary, if I understood well:
- you can patch your older CPU if you are still on older Windows 10 versions, which should be, by definition, less secure than the latest one
- you cannot patch your older CPU if you run the latest Windows build, which should be the one Microsoft focus its efforts on ?
Am I the only one who finds this situation non-sense ?

Is Sandy Bridge-E (3xxx series) included in this? I only see regular Sandy Bridge and Xeon counterparts listed by Microsoft.

Patched my install of W10 1803 manually yesterday. Boot up time is a few seconds quicker surprisingly after the update. Odd but at least my 2500k is a little more secure. I only play games so I shouldn't see much of an impact vs other tasks.
