用于电脑硬件性能参考的Win8.1系统体验评分找回方法【百科全说】

从微软Vista系统开始，微软为系统引入了一项性能信息和工具功能，用来检测系统体验评分，这项功能可以用于简单的电脑硬件性能的参考，一直延续Windows7，Windows8系统，但是到了Win8.1预览版以及Win8.1正式版后，这项功能直接默认隐藏，不再直观向用户显示。

为什么说是隐藏呢?

因为系统体验评分功能，就是WinSAT，用于Vista，Win7，Win8的性能信息和工具功能。而升级到Win8.1后，系统属性里面不再显示系统体验评分，但是WinSAT功能依旧存在于系统，支持将当前的系统评分分值直接以XML文本记录。

如何找回当前的系统体验评分信息?

方法一：适合高级用户

一、win+X，选择(以管理员身份)命令符，输入winsat -help，可查看到和Windows系统评估工具相关的命令行用法：

二、继续输入winsat formal，启动Windows系统评估工具

三：参考C:/Windows/Performance/WinSAT/DataStore路径，直接查找XML文本记录，默认有七个评分记录，分别为CPU，Disk，DWA，Graphics3D，GraphicsMedia，Mem，Formal。其中Formal.xml是对系统体验评分的汇总。

MemoryScore5.2对应内存RAM

CpuScore5.2对应处理器

GraphicsScore4对应图形性能

Dx9SubScore4.2对应DX9性能

GamingScore4.2对应游戏图形性能

DiskScore5.9对应主磁盘性能

方法二：适合普通用户

原理：添加PerfCenterCPL.dll应用程序扩展到Win8.1系统Windows目录下，并手动加载。即可在系统中添加一项性能信息和工具功能，直观显示Win8.1的系统各项指标的性能评分。

步骤：

1、下载PerfCenterCPL.dll应用程序扩展合集：

并复制system32和sysWOW64所有文件到Win8.1系统Windows目录下，支持32位系统和64位系统。

2、复制以下内容，另存为PerfCenter.reg，导入注册表，添加性能信息和工具功能

3、复制以下内容，另存为WinSAT.Bat，批量运行，开始系统体验评分测试。

@echo off

regedit /s PerfCenter.reg

regsvr32 /s "%SystemRoot%/System32/PerfCenterCPL.dll"

regsvr32 /s "%SystemRoot%/System32/WinSATAPI.dll"

regsvr32 /s "%SystemRoot%/System32/diagperf.dll"

regsvr32 /s "%SystemRoot%/System32/perftrack.dll"

regsvr32 /s "%SystemRoot%/SysWow64/PerfCenterCPL.dll"

regsvr32 /s "%SystemRoot%/SysWow64/WinSATAPI.dll"

4、运行后，打开控制面板，选择小类别，即可找到“性能信息和工具功能”，打开即可显示系统当前的系统评分内容。
