i found this program ExperienceIndexOK
it's portable , it has not an installation
do you think it a safe program?A small program and an effective solution to read and show your Windows Experience Index or to start a new calculation of the performance index.
The program is primarily written for Windows 8.1 and the Windows 10, because the performance index is calculated by the operating system, but the performance index is no longer displayed in the System.
Experience Index is optically, inspired by the representation on Windows 7
do you use it?
