As far as the earlier comments on the "other" testing methodologies.
Indexing is a setting in the Control Panel and not something you really benchmark. Technically, following the authors SSD recommendation will improve indexing.
Paging performance is really up to how the application uses memory and how the OS responds to that application request. Again, since paging uses disk, an SSD would provide the requisite levels of performance or use a small SSD for caching.
With regards to screen paging performance, (rarely tested anymore) is still done using the Passmark Performance Test tool.

Those of you who are avoiding Win10 (like me) for other non-technical reasons, be warned that MSFT is pushing up several KB's via Windows Update that provides the same level of "use monitoring" in Windows 7 that Windows 10 has out of the box. You can uninstall 2 of the KB's yourself and it breaks the activity and stops them from uploading further. The EULA with MSFT and Windows is pretty much like your smartphone now. They now have the right to collect data on how you use your PC all the time. If you are uncomfortable with it, be a nutter and stay on XP/Vista or move to Linux. I still know people running Windows 2000, for how much longer, who knows?
My surprise in this testing report is the lack of variance in encoding. The i5 used has some advanced vector and floating point features that reportedly Win10 exposes. Which probably means the test software wasn't looking for it.
As far as its use for desktop software, there used to be some Office automation test tools that could test the OS ability to handle OLE and DDE and certain .NET functions, but they have fallen by the wayside pretty much as the demand has waned to understand these. Mostly because the tests simply showed how well the hardware was able to overcome the limitations of Office coding.
Clearly benchmarking is about 3 areas today:
- Gaming (3D & Encoding)
- Browser performance (Cloud)
- Responsiveness (disk)
