Which OS Mode Should I Use?

WinStress Test PRO is compatible with Windows Pre-Installation Environment (WinPE) as well as standard Windows OS (Windows 7,8.1,10, Server)

For best test accuracy, we recommend utilizing a Windows PE environment when performing a concentrating stress test on core hardware components.

For stability, reliability & performance test sessions, we recommend using a full fresh installed Windows OS with all drivers and windows updates preinstalled.
