用 PowerShell 全自動比對 Windows 驅動版本──DriverCompare 腳本完整分享
想在多台測試機之間快速檢查 BIOS、EC、Windows Build 以及第三方驅動版本差異？這篇文章分享chatGPT製的 DriverCompare 腳本，讓你透過 PowerShell 一鍵產生差異報表，輕鬆掌握版本狀態。
目錄
- 需求與設計目標
- 資料夾結構
- 腳本下載與放置
- 使用流程（Baseline → 比對）
- driversDiff.csv 欄位解析
- 常見錯誤與排除
1 需求與設計目標
- 第一次執行：自動建立 baseline
- 後續執行：比對差異並輸出 driversDiff.csv
- 相容 PowerShell 5.1（移除
?:／??語法）
2 資料夾結構
起始只需要用notepad先建立compare-drivers.ps1 & run.bat,其他檔案會自動建立
compare-drivers
│ compare-drivers.ps1
│ run.bat
│ driversDiff.csv
├─baseline
│ baselineDrivers.csv
│ baselineInfo.txt
└─target
currentDrivers.csv
systemInfo.txt
3 腳本下載與放置
將整個 compare-drivers 資料夾放進 USB 隨身碟或共用資料夾，即可逐台執行。
4 使用流程
4-1 建立 Baseline
- 插上隨身碟 → 執行run.bat
螢幕顯示
Baseline done – move USB to next PC
即完成。
4-2 目標機比對
在其他機器重複執行，完成後會重新產生 driversDiff.csv。
5 driversDiff.csv 欄位解析
| Flag | Item | Baseline | Current | 說明 |
|---|---|---|---|---|
| DIFF | Windows Build | 19045 | 22631 | 系統版本不同 |
| XYZ Audio | 1.0.0.1 | 1.0.0.1 | 相同，Flag 留空 | |
| DIFF | Intel Wi-Fi | 22.230 | 目標機缺少此驅動 |
6 常見錯誤與排除
wmic : … not recognized→ 近版 Win11 移除 WMIC，可忽略 EC 比對或自行安裝 WMIC。Unexpected token '?' …→ 代表載入到舊腳本版本，請更新到本文腳本。- 若畫面顯示
!! Error，請打開 DriverCompare_error.log 追蹤細節。
