PC startup timeįor “boot time” tests, we used Microsoft’s “Windows ® Performance Toolkit”: These tools are used by software and hardware makers to test the impact of battery life and performance of their products on typical machines. So let’s have a look at the tests we performed before and after the upgrade to Windows 10 Build 10240 (final, including the latest updates as of July 27th, 2015): 1. Repeated all benchmark tests three times and then averaged the results Left all Windows optimization features enabled Ran all scheduled tasks and automated tasks using the “Rundll32.exe advapi32.dll,ProcessIdleTasks” command Put devices in a controlled room with 23° celcius and 250 (+/- 50) lux Then we prepared both installs as follows: To get reproducible and comparable results for Windows 8.1 versus Windows 10, we clean-installed both versions and installed only the latest drivers as well as our speed testing software, PCMark 8. It’s one of the hotter devices of 2015, and should definitely show if and how much Windows 10 is able to speed things up compared to the pre-installed Windows 8.1. It’s equipped with a Core i7 (which clocks up to 3.6 GHz), 16 GB of RAM, a rather powerful GeForce 960M GTX and a blazing-fast 128 GB SSD.

In our lab, we started our tests with a rather high-end multimedia notebook – the Asus UX-501.
